Previously, performance of stream.Parse could be limited by mutex.Lock on callback function. It used shared writeContext. With complicated relabeling rules and any slowness at pushData function, it could significantly decrease parsed rows processing performance.
This commit removes locks and makes parsed rows processing lock-free in the same manner as `stream.Parse` processing implemented at push ingestion processing.
Implementation details:
- Removing global lock around stream.Parse callback.
- Using atomic operations for counters
- Creating write contexts per callback instead of sharing
- Improving series limit checking with sync.Once
- Optimizing labels hash calculation with buffer pooling
- Adding comprehensive tests for concurrency correctness

Previously, `getBackupsList` was appending `latest` backup in all cases without checking if it actually exists.
This lead to `vm_backup_last_run_failed` metric being set to `1` since folder did not contain successful completion marker.
This commit adds a check to handle a case when remote storage does not contain any backups yet.

These errors could be caused by intermittent network issues, especially
in case of using proxies when accessing S3 storage. Previously, such
error would abort backup/restore process and require manual intervention
to ensure backups consistency.
This commit adds automatic retries to handle this to improve backups
reliability and resilience to network issues.
1. remove "vmalert" word from vmgateway doc and exposed metrics;
2. remove unrelated flags like -datasource.roundDigits, remoteRead.disablePathAppend, -datasource.disableStepParam
vmbackupmanager uses `runC` channel for inter-goroutine communication between `scheduler` and `execute` goroutines.
Previously, `runC` wasn't closed during graceful shutdown. And vmbackupmanager process couldn't gracefully stop. It could only be killed with-in configured timeout.
This commit properly closes `runC` by `scheduler` when stopping vmbackupmanager in order to avoid shutdown delay.

Previously, backup was first scheduled at 00:00:00 and `getSleepDuration` was immediately executed to get the sleep duration for the next backup. Since it was returning `1 * time.Second` the next backup was attempted and failed to be scheduled.
Update logic to wait for full backup interval in this case so that there will be no attempt to schedule an unneeded backup.
It also adds the following changes:
* fix error log entry reference to type of policy
* add a message about retention completion similar to existing message for backups to make it more consistent

Commit 9ca74d1fff introduced an issue with metrics registration. Due to metrics.Summary type always registered at the global state of metrics package, vmalert had increased memory and CPU usage after multiple configuration reloads.
This commit addresses this issue and properly registers metrics.Summary metric. Now metrics for group and rules must be explicitly registered before group.Start with group.Init method. It simplifies metrics usage an ensures that all needed metrics were registered and group is ready to start.
Related issue:
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/8532
1. fix possible data race on group checksum when reload is called
concurrently. Before, it didn't affect much but might update the group
one more time.
2. remove the unnecessary g.mu.RLock() and compute group.id at newGroup creation. Changes to group.ID()
indicate that type and interval have changed, and the group is new.

Previous commit 9ca74d1fff added a regression for notifier's metrics exposed by vmalert. vmalert returned new notifier instances for the blackhole notifier type. And it registered new metrics each get notifiers function was called. It registered duplicate metrics and lead to OOM crash.
This commit properly init blachole notifier instances and add metrics for it only once, during application start.

Previously, vmagent may incorrectly store partial scrape response
in case of scrapping error. It may happen if `sw.ReadData` call fetched
some chunked response and store it at buffer. And later context deadline
exceed error happened.
As a result, at the next scrape iteration this partial response could
be forwarded to the `sw.sendStaleSeries(lastScrape...)` function call
and lead to `Prometheus line` parsing error.
This commit properly set response body to the empty value in case of
scrapping error. It prevents storing partial scrape response body. And
it no longer sends partial staleness markers to the remote storage.

This commit adds lib/chunkedbuffer.Buffer - an in-memory chunked buffer
optimized for random access via MustReadAt() function.
It is better than bytesutil.ByteBuffer for storing large volumes of data,
since it stores the data in chunks of a fixed size (4KiB at the moment)
instead of using a contiguous memory region. This has the following benefits over bytesutil.ByteBuffer:
- reduced memory fragmentation
- reduced memory re-allocations when new data is written to the buffer
- reduced memory usage, since the allocated chunks can be re-used
by other Buffer instances after Buffer.Reset() call
Performance tests show up to 2x memory reduction for VictoriaLogs
when ingesting logs with big number of fields (aka wide events) under high speed.
Pre-allocate the needed slice of strings and then assign items to it by index
instead of appending them. This reduces the number of memory allocations
and improves performance a bit.
…an 64KB at Reset
This commit reverts
b58e2ab214
as it has negative impacts when ByteBuffer is used for workloads that
always exceed 64KiB size. This significantly slows down affected
components because:
* buffers aren't beign reused;
* growing new buffers to >64KiB is very slow.

- Properly decode protobuf-encoded Loki request if it has no Content-Encoding header.
Protobuf Loki message is snappy-encoded by default, so snappy decoding must be used
when Content-Encoding header is missing.
- Return back the previous signatures of parseJSONRequest and parseProtobufRequest functions.
This eliminates the churn in tests for these functions. This also fixes broken
benchmarks BenchmarkParseJSONRequest and BenchmarkParseProtobufRequest, which consume
the whole request body on the first iteration and do nothing on subsequent iterations.
- Put the CHANGELOG entries into correct places, since they were incorrectly put into already released
versions of VictoriaMetrics and VictoriaLogs.
- Add support for reading zstd-compressed data ingestion requests into the remaining protocols
at VictoriaLogs and VictoriaMetrics.
- Remove the `encoding` arg from PutUncompressedReader() - it has enough information about
the passed reader arg in order to properly deal with it.
- Add ReadUncompressedData to lib/protoparser/common for reading uncompressed data from the reader until EOF.
This allows removing repeated code across request-based protocol parsers without streaming mode.
- Consistently limit data ingestion request sizes, which can be read by ReadUncompressedData function.
Previously this wasn't the case for all the supported protocols.

The `ignore_fields` HTTTP query args can contain prefixes ending with '*'.
For example, `ignore_fields=foo.*,bar` skips all the fields starting with `foo.`
during data ingestion.
The optimization touches 2 things:
1. Reduces amount of allocations when comparing canonical metric names
between left and right parts of expressions.
2. Adds fast path for cases when right part of expression returns
scalar: `series_selector or on() vector(1)`, which is a typical
expression.

Long constant fields cannot be stored in columnsHeader as a const column,
because their size exceeds maxConstColumnValueSize, so they are stored as regular values.
This commit optimizes storing such fields by storing only a single value
across the field values in a block instead of storing multiple values.
This should improve data ingestion performance a bit. This also should improve query
performance when the query accesses such fields because of better cache locality.
Also improve persisting of constant string lengths by storing them only once.
Previously, vmselect didn't stop multitenant query execution if it
receives error from vmstorage. Such as limit error or any other. It
continued to execute queries until it did it for all tenants. It leads
to the potential waste of resources.
In addition, callback error was incorrectly reference and can be updated by
subsequent callback call.
This commit returns error earlier, cancels sub-sequent requests for
tenants and properly return storageNode request error.

Previously, if the command-line flag value `-remoteWrite.showURL` changed, vmagent dropped content of persistent queues. It's not expected behavior and may lead to data-loss at queue.
Further more if command-line flag value `-remoteWrite.showURL` is set to `true`, any changes to url query arguments will lead to persistent queue drop. The most common uses is kafka and gcp pub-sub integration. It uses url query arguments for client configuration.
Also, it complicates copy content of persistent queue between vmagents. Since it requires to properly change name inside metainfo.json.
This commit removes persistent queue name equality check from `lib/persistentqueue`. This check was added as an additional protection from on-disk data corruption.
It's safe to skip this check for vmagent, because vmagent encodes remoteWrite.url as part of path to the queue. It guarantees that there will be no collision.

Almost all storage API operations, both ingestion and retrieval, involve
writing and/or reading the indexdb. However, during these operations,
the indexdb refcount is not incremented. This may lead to panics if
indexdb is rotated more than once during these operations.
This commit increments the refcount before using indexdb and decrements it
after use.
Note that rotating indexdb more than once during some operation is an
impossible case under normal circumstances as the min retention period
is 1 day (i.e. the indexdb will be rotated once per day). However, we
want the storage to behave correctly in all cases.

Loki doesn't support well high-cardinality log fields (e.g. fields with big number of unique values).
That's why Promtail, Grafana Agent and Grafana Alloy encode such fields into a JSON and push them
as a plaintext log message to the remote storage. This isn't an efficient way to store high-cardinality
log fields in VictoriaLogs, since it is optimized for storing and querying such fields when they are stored
distinctly as a regular log fields according to VictoriaLogs data model ( https://docs.victoriametrics.com/victorialogs/keyconcepts/#data-model ).
This commit enables automatic parsing of JSON-encoded log fields at plaintext log message received over Loki protocol
and storing them as a separate log fields. This should improve data compression ratio and reduce disk space usage.
This should also improve query performance when the parsed log fields are used in queries for filtering and aggregation.
The old behaviour can be restored by passing -loki.disableMessageParsing command-line flag to VictoriaLogs.

Fix metric that shows number of active time series when per-day index is disabled. Previously, once per-day index was disabled, the active time series metric would stop being populated and the `Active time series` chart would show 0.
See: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/8411.
- Properly handle negative timestamps (e.g. timestamps before 1970-01-01)
- Optimize parsing floating-point timestamps by eliminating the memory allocation
needed for returning an error from strconv.ParseInt. Instead, check whether the string contains a dot,
and then parse it as a floating-point number.
- Add tests for ParseUnixTimestamp function.
- Make the code easier to understand and maintain by removing unneeded generic function toNano().

### Fix scrapePool name
If in the scrape file, I do some magic and manipulate the job name then
Prometheus will show scrapePool as the original job name in the targets

...
- source_labels: [ __meta_consul_service ]
regex: (\w+)[_-]exporter
target_label: job
replacement: $1

curl to prom API will show
`"scrapePool": "consul-targets",`
vmagent:
`""scrapePool": "node",`

```
curl -s 'http://localhost:8429/api/v1/targets' | jq -r '.data.activeTargets[].scrapePool'| sort|uniq

This feature allows to track query requests by metric names. Tracker
state is stored in-memory, capped by 1/100 of allocated memory to the
storage. If cap exceeds, tracker rejects any new items add and instead
registers query requests for already observed metric names.
This feature is disable by default and new flag:
`-storage.trackMetricNamesStats` enables it.
New API added to the select component:
* /api/v1/status/metric_names_stats - which returns a JSON
object
with usage statistics.
* /admin/api/v1/status/metric_names_stats/reset - which resets internal
state of the tracker and reset tsid/cache.
New metrics were added for this feature:
* vm_cache_size_bytes{type="storage/metricNamesUsageTracker"}
* vm_cache_size{type="storage/metricNamesUsageTracker"}
* vm_cache_size_max_bytes{type="storage/metricNamesUsageTracker"}

### Describe Your Changes
Previously, "selector @ another_selector" assumed that
"another_selector" metric is supposed to exist since "start" used in the
query.
If the query was evaluated in the following case (timestamps):
- start - 2, end - 10
- "another_selector" 5,6,7,8,9,10
- "selector" The resulting "at" timestamp would be taken from NaN (as
`int64(NaN * 1000)`), causing a panic or invalid behavior later.
Note that type cast of `NaN` to int64 is also platform-dependent, so
value of `int64(math.NaN() * 1000)` can produce `0` or max int64 on
different platforms and versions of Go.
This commit changes this and checks for the first non-NaN value. This
makes it easier to use for users as series are not always aligned and
returning an error in this case would disallow using this for some time
ranges.

Since funcs `ParseDuration` and `ParseTimeMsec` are used in vlogs,
vmalert, victoriametrics and other components, importing promutils only
for this reason makes them to export irrelevant
`vm_rows_invalid_total{type="prometheus"}` metric.
This change removes `vm_rows_invalid_total{type="prometheus"}` metric
from /metrics page for these components.

`MustParsePromMetrics` imports `lib/protoparser/prometheus`, and this
package exposes the following metrics:
```
vm_protoparser_rows_read_total{type="promscrape"}
vm_rows_invalid_total{type="prometheus"}
```
It means every package that uses `lib/prompbmarshal` will start exposing
these metrics. For example, vlogs imports `lib/protoparser/common` which
uses `lib/prompbmarshal.Label`. And only because of this vlogs starts
exposing unrelated prometheus metrics on /metrics page.
Moving `MustParsePromMetrics` to `lib/protoparser/prometheus` seems like
the leas intrusive change.

Updated `publish-via-docker` task to push images to multiple registries
as defined by `DOCKER_REGISTRIES`. By default, publish pushes images to
both docker.io and quay.io. It is possible to choose a single repo by
overriding `DOCKER_REGISTRIES`, for example: `DOCKER_REGISTRIES=quay.io
make publish-victoria-logs`
Note that `package-via-docker` task is not using multiple registries as
there is usually little sense in building same image with different tags
for local use.

This allows using different intervals for flushing in-memory data among different mergeset.Table instances.
The initial user of this feature is lib/logstorage.Storage, which explicitly passes Storage.flushInterval
to every created mereset.Table instance. Previously mergeset.Table instances were using 5 seconds
flush interval, which didn't depend on the Storage.flushInterval.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4775
The new version of github.com/VictoriaMetrics/metricsql handles $__interval and $__rate_interval
inside rollup functions in more correct way - it drops square brakets, so VictoriaMetrics
could automatically detect the needed lookbehind window depending on the time distance between real samples.
For example, rate(m[$__rate_interval]) is parsed and processed as rate(m) now.
Make sure that the maximum log field name, which can be generated by JSONParser.ParseLogMessage,
doesn't exceed the hardcoded limit maxFieldNameSize. Stop flattening of nested JSON objects
when the resulting field name becomes longer than maxFieldNameSize, and return the nested JSON object
as a string instead.
This should prevent from parse errors when ingesting deeply nested JSON logs with long field names.

> (currently in DRAFT) This dashboard and the docs may look differently
after recent review and the feedback received.
As requested by our customers, this PR introduces `anomaly score`-based
dashboard for `vmanomaly` to improve the visual experience and ease the
drill down debugging process for respective anomaly detection setups.
Accompanying guide (under `default` preset mode) is provided as well.
- [For additional
benefits](https://docs.victoriametrics.com/victoriametrics-datasource/#motivation),
the dashboard is based on [VictoriaMetrics
datasource](https://docs.victoriametrics.com/victoriametrics-datasource/)
rather than on `Prometheus` datasource
- Tested locally and on our https://play.victoriametrics.com/

- To check the guide, build the docs locally (`vmdocs`, `make run
local`) and follow to the

Previously if rule group parameters were changed, alerting rules related metrics could be deleted due to bug at `utils/metrics` package.
This commit introduces `metrics.Set` per rule group. It holds group and alerting rules metrics. It properly unregister alerting rules metrics and addresses issue.
In addition:
- expose group metrics only once group is started - this helps to avoid
exposing metrics for groups which are created during YAML unmarshaling
and only used to update existing group.
- properly close rules which are discarded after updating existing rules
so that metrics are also correctly closed.
- detect file renames and properly recreate groups "moved" between files.

Examples:
- `top 5 x, y` is equivalent to `top 5 by (x, y)`
- `uniq foo, bar` is equivalent to `uniq by (foo, bar)`
- `unroll foo, bar` is equivalent to `unroll (foo, bar)`
_time:<=max_time filter must include logs with timestamps matching max_time.
For example, _time:<=2025-02-24Z must include logs with timestamps until the end of February 24, 2025.
Examples:
_time:>=2025-02-24Z selects logs with timestamps bigger or equal to 2025-02-24 UTC
_time:>1d selects logs with timestamps older than one day comparing to the current time
This simplifies writing queries with _time filters.

### Describe Your Changes
By default, stream aggregation and deduplication stores a single state
per each aggregation output result.
The data for each aggregator is flushed independently once per
aggregation interval. But there's no guarantee that
incoming samples with timestamps close to the aggregation interval's end
will get into it. For example, when aggregating
with `interval: 1m` a data sample with timestamp 1739473078 (18:57:59)
can fall into aggregation round `18:58:00` or `18:59:00`.
It depends on network lag, load, clock synchronization, etc. In most
scenarios it doesn't impact aggregation or
deduplication results, which are consistent within margin of error. But
for metrics represented as a collection of series,
like
[histograms](https://docs.victoriametrics.com/keyconcepts/#histogram),
such inaccuracy leads to invalid aggregation results.
For this case, streaming aggregation and deduplication support mode with
aggregation windows for current and previous state. With this mode,
flush doesn't happen immediately but is shifted by a calculated samples
lag that improves correctness for delayed data.
Enabling of this mode has increased resource usage: memory usage is
expected to double as aggregation will store two states
instead of one. However, this significantly improves accuracy of
calculations. Aggregation windows can be enabled via
the following settings:
- `-streamAggr.enableWindows` at [single-node
VictoriaMetrics](https://docs.victoriametrics.com/single-server-victoriametrics/)
and [vmagent](https://docs.victoriametrics.com/vmagent/). At
[vmagent](https://docs.victoriametrics.com/vmagent/)
`-remoteWrite.streamAggr.enableWindows` flag can be specified
individually per each `-remoteWrite.url`.
If one of these flags is set, then all aggregators will be using fixed
windows. In conjunction with `-remoteWrite.streamAggr.dedupInterval` or
`-streamAggr.dedupInterval` fixed aggregation windows are enabled on
deduplicator as well.
- `enable_windows` option in [aggregation
config](https://docs.victoriametrics.com/stream-aggregation/#stream-aggregation-config).
It allows enabling aggregation windows for a specific aggregator.

### Describe Your Changes
This PR introduces several enhancements and optimizations for the Group
view:
1. **Disable hover effect:**
Add the option to disable the hover effect. This can help reduce CPU
load when viewing a large number of logs.
2. **Limit entries per Group:**
Add the ability to limit the number of records displayed per group. When
a limit is set, groups are rendered sequentially – the next group starts
only after the current group has finished. By default, there is no
limit.
3. **Display group info:**
Include the group number in the title along with the total count of
groups to improve clarity and navigation.
4. **Performance improvement:**
In addition to the features above, separate optimizations reduce CPU
load during hover interactions by approximately 5-10%.

It has been appeared these optimizatios do not give measurable performance improvements,
while they complicate the code too much and may result in slowdown when the ingested logs have
different sets of fields.
This is a follow-up for 630601488e
It has been appeared that 256 files increase RAM usage too much comparing to 128 files
when ingesting logs with hundreds of fields (aka wide events). So let's return back 128 files
limit for now.
This is a follow-up for 9bb5ba5d2f
There is little sense in keeping too big buffers - they just waste RAM and do not reduce
the load on GC too much. So it is better dropping such buffers at Reset instead of keeping them around.
The number of filestream readers is proportional to the number of parts to be merged,
while the number of filestream writers is proportional to the number of concurrent merges.
Usually around 4-16 parts are merged at once, so the number of active filestream readers is ~8x
bigger than the number of active filestream writers.
So it is a good idea to use smaller size of read buffers comparing to the size of write buffers.
Limit read buffer size by 64Kb, while write buffer size is limited by 128Kb.
This should reduce the overall memory usage when merging parts with big number of files.
This is the case for VictoriaLogs, which works with logs containing hundreds of fields (aka wide events).

This should improve query performance for logs with hundreds of fields (aka wide events).
Previously there was a high chance that the data for multiple log fields is stored in the same file.
This could result in query performance slowdown and/or increased disk read IO,
since the operating system could read unnecessary data for the fields, which aren't used in the query.
Now log fields are guaranteed to be stored in separate files until the number of fields exceeds 256.
After that multiple log fields start sharing files.
This reduces memory usage when many filestreams are processed simultaneously.
This is the case for VictoriaLogs when it processes logs with hundreds of fields.
- Re-use column names and values from the previously added rows if possible.
This increases locality of reference for field names and values, while improving
access speed for the field names and values.
- Postpone sorting fields in the added rows until creating inmemory part from them.
This allows optimizing the sorting for log fields with the same set of fields.
This is usually the case for logs, which belong to the same logs stream.
In this first step, content is moved from cloud docs root to a new
folder: get started. This one will allocate: overview, key features and

Some of the test cases were failing because of the changes in data sharding
caused by changes in vmstorage ports caused by cluster restarts required by the
test.
This commit configures the cluster under test to use static ports for vmstorage
replicas. This required to make vmcluster type to become visible to tests.
We normally prefer ports assigned dynamically to avoid any conflicts with other
apps running locally. Should the conflict happen, please re-run the tests.
In CI/CD environment, no conflicts should happen because the tests are run
within a container and the components of the vmcluster will be the only servers

There are many subtle issues while ingesting logs from popular log shippers into VictoriaLogs via Loki JSON protocol.
For example, the common issue is that structured logs are ingested as a JSON string at _msg field.
This is not what most users expect - they expect that fields in structured logs are ingested as separate log fields.
It is better removing examples with configs for Loki JSON protocol, since other supported protocols work much better
without any issues. This should reduce the confusion level for new users, who try Loki protocol and hit its issues.

- JSON stream ( https://docs.victoriametrics.com/victorialogs/data-ingestion/#json-stream-api )

1. Use distinct code paths for blockResult.getValues() and blockResult.getValuesBucketed().
This should simplify debugging and maintenance of the resulting code.
2. Do not load column values if all the values in the block fit the same bucket.
Use blockResultColumn.minValue and blockResultColumn.maxValue for determining whether
column values must be loaded via blockResultColumn.getValuesEncoded().
This signiciantly improves performance for big buckets, which cover all the column
values in a block.
3. Properly calculate buckets for negative values.
4. Properly adjust weekly buckets by Monday.

Adding Accept-Encoding response header to support content negotiation,
which was introduced in [this
PR](https://github.com/systemd/systemd/pull/34822) and enables
compression on journald
Previously the `callbackErr` is silently ignored in clusternative parser, which is used at vminsert for parsing clusterNative requests and at vmstorage for parsing vminsert requests.
This commit fixes that by properly return callbackError after reading all block metrics. This aligns
with other parsers in `lib/protoparser`.
### Describe Your Changes
Updated default `step` calculation for `Table` and `JSON` views.
- When switching to the `Table` or `JSON` view, the default step is now
automatically set to `end - start`, where `end` and `start` correspond
to the selected time range.
- If the user has manually set a step value, it will remain unchanged
when switching views or changing the time range.
- The UI now explicitly indicates when the step is automatically
calculated.

This improves performance for queries, which use `sort by (...) limit N` without mentioning _time field.
For example, the following query must work faster now
_time:1d | rm _time | sort by (request_duration desc) limit 10
- Add a fast path for timestamps ending with 'Z'
- Use strings.LastIndexAny instead of strings.IndexAny for searching
for timezone offset at the end of the string. This works faster
for timestamps with sub-second precision.
The 2025 changelog was in the parent directory - a default page

But it seems like it was confusing for users, so add 2025 that mirrors

Update the pipe state only once per each series of repeated strings, uint8 values and tuples.
This improves performance a bit for the following `top` pipes:
- top (string_field)
- top (uint8_field)
- top (field1, ..., fieldN)
Do not apply the optimization for uint16, uint32, uint64 and int64 fields, since they
usually contain big number of unique values, which do not repeat most of the time.
### Describe Your Changes
There is an issue described in #8040 this should fix it
- The alerts slice is shared across multiple goroutines (since send() is
called concurrently).
- `alerts[:0]` creates a new slice header, but it still references the
same underlying array.
- Appending (append(alertsToSend, a)) modifies the underlying array,
which may also be used by another goroutine.
Solution: Use a separate slice copy for each goroutine.

Previously RFC3339 timestamps with sub-second precision could be incorrectly compared by lessString().
For example, 2025-01-20T10:20:30.1Z was incorrectly treated as smaller than 2025-01-20T10:20:30.09Z,
because the first timestamp has smaller decimal number after the last dot than the second timestamp.
Previosly the parsing of the input stream was stopped after the first parse error.
This isn't what most users expect when ingesting JSON lines in a stream where some JSON lines may be invalid.
### Describe Your Changes
- Migrated build process from Webpack (CRA) to Vite
Reason for migration: `create-react-app` has been
[deprecated](b532a58792)
and contains outdated dependencies that haven’t been updated for over
two years, leading to security vulnerabilities. Additionally, build
speed improved by more than 2x.
- Updated dependencies and fixed TypeScript typings in accordance with

Split unique values (groups) into shards according to the configured concurrency
during processing of the matching rows if the number of unique values exceeds the hardcoded threshold.
Previously this splitting was performed unconditionally at the merge stage when merging independently
calculated per-CPU states into a single state. It is faster to perform the split during rows processing
if the number of unique values is big.
This gives up to 30% perfromance improvements when these pipes are applied to big number of unique values (groups).
The number of worker shards per each pipe processor is created during query initialization.
This number equals to the `options(concurrency=N)` if this option is set or to the number of available CPU cores.
This means that all the pipes must adhere the given concurrency when passing data blocks
to the next pipe.
See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/8201
The bug has been introduced in 0214aa328e
vmauth uses 'lib/httpserver' for serving HTTP requests. This server
unconditionally defines built-in routes (such as '/metrics',
'/health', etc). It makes impossible to proxy `HTTP` requests to backends with the same routes.
Since vmauth's httpserver matches built-in route and return local
response.
This commit adds new flag `httpInternalListenAddr` with
default empty value. Which removes internal API routes from public
router and exposes it at separate http server.
For example given configuration disables private routes at `0.0.0.0:8427` address and serves it at `0.0.0.0:8426`:
`./bin/vmauth --auth.config=config.yaml --httpListenAddr=:8427 --httpInternalListenAddr=127.0.0.1:8426`

This commit improves integration with third-party solutions who rely on non-root
endpoints (i.e. MinIO) when the vmselect path has been specified in the
configured Prometheus URL like:
`http://vmselect.:8481/select/0/prometheus`
Comparable change has been done before
(b885a3b6e9), however only takes care of
the root path. This means endpoints `-/healthy` and `-/ready` are still
not available on full vmselect Prometheus paths, resulting in
unsupported path requests.
This change makes these endpoints available on the full paths like:
`/select/0/prometheus/-/healthy` and `/select/0/prometheus/-/ready`,
thus achieving full Prometheus compatibility for external dependencies.

### Describe Your Changes
The cardinality limiter in this case does not receive the actual
metricID but some other value found in r.TSID.MetricID and is not
initialized. Depending on the system and/or go runtime implementation,
this value can be 0 or some garbage value (which shouldn't have too wide
a range). Thus, there basically no limit for inserted metricIDs.

At this time `bufferedwriter` [silently ignores connection close
errors](78eaa056c0/lib/bufferedwriter/bufferedwriter.go (L67)).
It may be very convenient in some situations (to not log such
unimportant errors), but it's too implicit and unsafe for the others.
For example, if you close [export
API](https://docs.victoriametrics.com/#how-to-export-time-series) client
connection in the middle of communication, VictoriaMetrics won't notice
it and will start to hog CPU by exporting all the data into nowhere
until it process all of them. If you'll make a few retries, it will be
effectively a DoS on the server.
This commit replaces this implicit error suppressing with explicit error
handling which fixes the issue with export API.

This should reduce the time needed for opening the storage with retentions exceeding a few months.
While at at, limit the concurrency of opening partitions in parallel to the number of available CPU cores,
since higher concurrency may increase RAM usage and CPU usage without performance improvements

### Describe Your Changes
- Added the `fields_limit` parameter for the `hits` query to limit the
number of returned fields. This reduces the response size and decreases
memory usage.
#### Legend Menu:
A context menu has been added for legend items, which includes:
1. Metric name
2. **Copy _stream name** - copies the full stream name in the format
`{field1="value1", ..., fieldN="valueN"}`.
3. **Add _stream to filter** - adds the full stream value to the current
filter:
`_stream: {field1="value1", ..., fieldN="valueN"} AND (old_expr)`.
4. **Exclude _stream from filter** - excludes the stream from the
current filter:
`(NOT _stream: {field1="value1", ..., fieldN="valueN"}) AND (old_expr)`.
5. List of fields with options:
- Copy as `field: "value"`.
- Add to filter: `field: "value" AND (old_expr)`.
- Exclude from filter: `-field: "value" AND (old_expr)`.
6. Total number of hits for the stream.

The purpose of extra filters ( https://docs.victoriametrics.com/victorialogs/querying/#extra-filters )
is to limit the subset of logs, which can be queried. For example, it is expected that all the queries
with `extra_filters={tenant=123}` can access only logs, which contain `123` value for the `tenant` field.
Previously this wasn't the case, since the provided extra filters weren't applied to subqueries.
For example, the following query could be used to select all the logs outside `tenant=123`, for any `extra_filters` arg:
* | union({tenant!=123})
This commit fixes this by propagating extra filters to all the subqueries.
While at it, this commit also properly propagates [start, end] time range filter from HTTP querying APIs
into all the subqueries, since this is what most users expect. This behaviour can be overriden on per-subquery
basis with the `options(ignore_global_time_filter=true)` option - see https://docs.victoriametrics.com/victorialogs/logsql/#query-options
Also properly apply apply optimizations across all the subqueries. Previously the optimizations at Query.optimize()
function were applied only to the top-level query.
logger.Fatalf("BUG: ...") complicates investigating the bug, since it doesn't show the call stack,
which led to the bug. So it is better to consistently use logger.Panicf("BUG: ...") for logging programming bugs.
Previously, NewChild elements of querytracer could be referenced by concurrent
storageNode goroutines. After earlier return ( if search.skipSlowReplicas is set), it is
possible, that tracer objects could be still in-use by concurrent workers.
It may cause panics and data races. Most probable case is when parent tracer is finished, but children
still could write data to itself via Donef() method. It triggers read-write data race at trace
formatting.
This commit adds a new methods to the querytracer package, that allows to
create children not referenced by parent and add it to the parent later.
Orphaned child must be registered at the parent, when goroutine returns. It's done synchronously by the single caller via finishQueryTracer call.
If child didn't finished work and reference for it is used by concurrent goroutine, new child must be created instead with
context message.
It prevents panics and possible data races.

This is done via 'options(concurrency=N)' prefix for the query.
For example, the following query is executed on at most 4 CPU cores:
options(concurrency=4) _time:1d | count_uniq(user_id)
This allows reducing RAM and CPU usage at the cost of longer query execution times,
since by default every query is executed in parallel on all the available CPU cores.
See https://docs.victoriametrics.com/victorialogs/logsql/#query-options
Also always initialize Query.timestamp with the timestamp from the lexer.
This should avoid potential problems with relative timestamps inside inner queries.
For example, the `_time:1h` filter in the following query is correctly executed
relative to the current timestamp:
foo:in(_time:1h | keep foo)

`doInternal` has adaptive staleness detection mechanism. It is
calculated using timestamp distance between samples in selected list of
samples. It is dynamic because VM can store signals from many sources
with different samples resolution. And while it works for most of cases,
there are edge cases for rollup functions that are comparing values
between windows: increase, increase_pure, delta.
The edge case 1.
There was a gap between series because of the missed scrape or two. In
this case staleness will trigger and increase-like functions will assume
the value they need to compare with is 0. In result, this could produce
spikes for a flappy data - see
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/894 This
problem was solved by introducing a `realPrevValue` field -
1f19c167a4.
It stores the closest real sample value on selected interval and is used
for comparison when samples start after the gap.
The edge case 2.
`realPrevValue` doesn't respect staleness interval. In result, even if
gap between samples is huge (hours), the increase-like functions will
not consider it as a new series that started from 0. See
https://github.com/VictoriaMetrics/VictoriaMetrics/pull/8002.
Covering both edge cases is tricky, because `realPrevValue` has to
respect and not respect the staleness interval in the same time. In
other words, it should be able to ignore periodic missing gaps, but
reset if the gap is too big. While "too big gap" can't be figured out
empirically, I suggest using `-search.maxStalenessInterval` for this
purpose. If `-search.maxStalenessInterval` is set to 0 (default), then
`realPrevValue` ignores staleness interval. If
`-search.maxStalenessInterval` is > 0, then `realPrevValue` respects it
as a staleness interval.

Commit eef6943084 added new test
functions. Which checks various cases for metricName registration at
data ingestion.
Initial dataset size had 4 batches with 100 rows each. It works fine at
machines with 5GB+ memory.
But i386 architecture supports only 4GB of memory per process.
Due to given limitations, batch size should be reduced to 3 batches and
30 rows. It keeps the same
test funtionality, but reduces overall memory usage to ~3GB.

This allows reducing the state of every statsProcessor by removing pointer to the corresponding statsFunc.
For example, this reduces statsCountProcessor size by 2x.
Previoysly finalizeStats() for some functions such as count_uniq() could run for long periods
of time after the query is canceled, since stopCh wan't propagated to finalizeStats().
Prevsiously integer values were converted to strings before being passed to `updateState()` function at `count_uniq`
and `count_uniq_hash`. Later such values are converted back to integers in order to track them via integer map of unique values.
This commit avoids the int -> string -> int conversion. Instead, it passes integers directly to the integer map of unique values.
This improves performance of `count_uniq` and `count_uniq_hash` functions even further.
This filter can be used when debugging and exploring logs in order to understand better
which value types are used for storing the particular log fields.
The `value_type` filter complements `block_stats` pipe.
Add exclude google.golang.org/grpc/stats/opentelemetry v0.0.0-20240907200651-3ffb98b2c93a to go.mod
according to https://github.com/googleapis/google-cloud-go/issues/11283#issuecomment-2558515586 .
This fixes the following strange issue on `make vendor-update`:
cloud.google.com/go/storage imports
google.golang.org/grpc/stats/opentelemetry: ambiguous import: found package google.golang.org/grpc/stats/opentelemetry in multiple modules:

- Pass the calculated results to the next pipe in float64 columns.
Previously the results were converted to string columns. This could slow down further calculations.
- Use custom optimized logic for processing numeric columns, which are passed to math pipe.
Previously all the input columns were converted to string and then converted to float64
before math pipe calculations.
- Initialize the newly added columns at blockResult as soon as they are added.
This improves performance when big number of columns are calculated by math pipe.
Previously integer values were tracked in string maps. Now every input value is parsed as integer.
On success the parsed integer is tracked via specialized maps, which hold only integers.
This reduces CPU usage and memory usage in general case.
Use the column name attached to the corresponding part. The lifetime of this column name exceed the blockSearch lifetime,
so it is safe using it here.
This is a follow-up for 8d968acd0a
Previously columns with negative int64 values were stored either as float64 or string
depending on whether the negative int64 values are bigger or smaller than -2^53.
If the integer values are smaller than -2^53, then they are stored as string, since float64 cannot
hold such values without precision loss. Now such values are stored as int64.
This should improve compression ratio and query performance over columns with negative int64 values.
Previously field values could be automatically converted to float64 with precision loss.
This could lead to unexpected results when querying such field values.
For example, "10007199254740992" was incorrectly represented as 10007199254740993.
This commit prevents from such lossy conversions when storing field values.
While at it, prevent from int64 overflow at tryParseBytes and tryParseDuration functions,
which are used for parsing constants in queries for byte sizes and durations.
Now these functions return 1<<63-1 (the maximum int64 value) for constants exceeding
this value. Previously they could return arbitrary garbage for such constants.
1. Do not copy every line from LineReader.buf to LineReader.Line - just refer the line at LineReader.buf.
2. Do not copy the next found line to the beginning of LineReader.buf - just track the next line start index with LineReader.bufOffset.
This reduces memory copying when many lines are read into LineReader.buf by a single read() syscall.
When vmselect process a rollup function it fetches all the raw samples
on requested `start-end` interval of the query. It then loops through
the raw samples, picks the range of the samples based on provided `step`
interval and invokes a rollup function for each of the picked ranges of
samples.
During this processing, vmselect always populates the `realPrevValue`
field with the closest previous raw sample value before the picked range
of samples. This `realPrevValue` is used by rollup functions like
increase_pure or delta to decide whether the counter change happened or
not. For example, we get the counter value == 1. If we've seen this
counter before and its value was also 1 - then no change happened. If we
didn't see it before, then this counter should have started with value=0
and we need to account for `1-0=1` change. All this is required to deal
with situations when scrapes are missing or `step` is too small.
However, vmselect doesn't check how "old" is the `realPrevValue`. In
other words, it doesn't respect the staleness interval when picking it.
In result, depending on the `start` and `end` params, vmselect can use
`realPrevValue` which is a couple of hours old and is unlikely to be a
temporary scrape fail. In result, some increases can be incorrectly
ingnored by vmselect.
This change makes sure that vmselect doesn't populate `realPrevValue`
with samples that are older than staleness interval.

-------------------
To reproduce, create a dataset with one metric `foo` which has samples
with value=1 on interval of couple of hours and resolution 15s, and a
gap for an hour in the middle:
<img width="769" alt="image"
src="https://github.com/user-attachments/assets/a39b2740-b741-45f8-ad18-093b7c57c3b3"
/>
Then run `increase(foo[1m])` expression on this time range (disable
cache):
<img width="1472" alt="image"
src="https://github.com/user-attachments/assets/463cece1-f359-4c75-a96c-60092a31cab2"
/>
In result, there will be one increase on the beginning of the series.
And no increase after the gap. Then change the time range so it starts
in the middle of the gap:
<img width="1505" alt="image"
src="https://github.com/user-attachments/assets/f4a460c3-9fd1-4ec7-ab47-15e716ec1019"
/>
Now, there is an increase>0 because the `realPrevValue` wasn't
populated. This is wrong, because it hides the increase of the series.
With the fix, the original increase query on full time range should show
2 increases:
<img width="1492" alt="image"

`evalNumber` function no longer updating MetricName tenancy information.
This leads to mismatch in metric names between the query result and
evaluated number for all tenants other than 0:0.
For example, query `count(up) or 0` will return different results for
tenants 0:0 and 1:1 (assuming up is present for both tenants):
- tenant 0:0 - will only contain result of `count(up)`
- tenant 1:1 - will return both `count(up)` and `0` since metric names
will not be matched
This restores setting of tenancy information for metric name for
single-tenant queries.

Hint allows to choose type of cache to be used for index search:
- in-memory parts are storing recently ingested samples and should use
main cache. This improves ingestion speed and cache hit ration for
queries accessing recently ingested samples.
- merges of file parts is performed in background, using a separate
cache allows avoiding pollution of the main cache with irrelevant
entries.

### Describe Your Changes
Binary operations like `exprFirst op exprSecond` in VictoriaMetrics are
performed in the following way:
1. Execute exprFirst.
2. Extract **common label filters** from the result of step 1.
3. Apply these common label filters to `exprSecond` and execute it, in
order to retrieve less time series from vmstorage nodes.
In step 2, only labels with less than `100` (hard-coded) value could be
used as **common label filter** (e.g. `{common_lb=~"v1|v2|...|v100"}`.
In our scenarios, a label, take `instance` label as an example, could
has thousands of candidate values. Regarding bring more pressure to
vmstorage node, it's still beneficial if labels with more than 100
values could be used as filter in `exprSecond`, with enough vmstorage
resources. After adjusting the value from `100` to `10000`, our query
round-trip time drops significantly from 5s to 2s.
This pull request change the hard-coded value into a configurable flag.
storageNode sorting should be BUGFIX, since previously vminsert performed sort and this behaviour was changed.
Also this change only affects OSS version
### Describe Your Changes
Parse cache is a pretty simple implementation of cache. It's just a
standard map with mutex.
Map with mutex overall has poor performance, plus when the cache
overflow occurs, the whole cache locks until 1k elements have been
deleted (now it's 10% of 10000 max elements in the cache). To avoid this
bottleneck and improve performance of cache on systems with many CPU
cores but keep it rather simple, we can implement cache with per bucket
locks like it's done in fastcache. The logic and API remain the same. So
now each bucket will have a map with approximately 78 elements (with 128
buckets), and overflow will occur now for each bucket, and only 7
elements need to be deleted.
Because exec_test.go has about 10k lines of code, it's better to move
the cache into a separate file to add tests and benchmarks for it,
because now it does not have them.

### Checklist
The following checks are **mandatory**:
- [x] My change adheres [VictoriaMetrics contributing
guidelines](https://docs.victoriametrics.com/contributing/).
consistently use `vmagent_remotewrite_pending_data_bytes` on vmagent dashboard to represent persistent queue size.
`vmagent_remotewrite_pending_data_bytes =
vm_persistentqueue_bytes_pending + pendingInmemoryBytes`
According to panel description, `vmagent_remotewrite_pending_data_bytes`
is more accurate.
>Persistent queue size shows size of pending samples in bytes which
hasn't been flushed to remote storage yet.
And we already use `vmagent_remotewrite_pending_data_bytes` in other two
panels.
44d2205136/dashboards/vmagent.json (L7132)
- removed absolute paths to run without docker
- set cspell to default entrypoint value
- set cspell config path instead of cspell.json copying and removal
Previously, since labels slice is reused for both `ALERTS` and
`ALERTS_FOR_STATE`, metrics might have incorrect labels and affect the
restore process. Tested the fix under `TestAlertingRule_Exec:
"for-pending=>empty"`.
The bug is introduced in
282f13cf11.
Affected versions: v1.106.1, v1.107...v1.108.x
related issue:
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7796
At Enterprise version of the vmalert, `group` supports `tenant` field.
`tenant` field value must be added to the `datasource` as a part of the URL path prefix.
But VictoriaLogs can obtain tenant information only from `headers` and defined `tenant` breaks requests to the `VictoriaLogs` datasource.
This commit properly checks `datasourceType` and skips adding path prefix if `datasourceType` is `vlogs`.

previously vmstorage ignored limit values from vmselect component.
This behavior is prohibited starting from v1.105.0, with
85f60237e2.
This breaks the original intent of the -search.maxUniqueTimeseries command-line flag, which has been added at vmselect nodes in the commit b843f0e : to be able to override the default limit at vmstorage on the number of unique time series, at different subsets of vmselect nodes.
The behavior should be the following:
* If -search.maxUniqueTimeseries command-line flag isn't set at both vmselect and vmstorage nodes, then the limit on the number of unique time series must be automatically detected at vmstorage nodes according to
* vmstorage: automatically adjust -search.maxUniqueTimeseries max value . This simplifies configuration of VictoriaMetrics cluster for the typical case.
* If -search.maxUniqueTimeseries command-line flag is explicitly set at vmstorage node, then it must be used as the limit on the number of unique time series, without automatic detection of the limit. Explicitly set limit at vmstorage node cannot be exceeded by the limit from vmselect nodes.
* If the -search.maxUniqueTimeseries command-line flag is explicitly set at vmselect node, then it must override the automatically detected limit at vmstorage node. For example, if vmselect node provides the limit, which exceeds the automatically detected limit at vmstorage node, then the limit from the vmselect node must be applied during query execution at vmstorage node. This will allow properly executing queries from the subset of vmselect nodes for reporting queries described above.

### Describe Your Changes
Previously, vmctl expect that tag must exist for each measurement, but
it's actually not necessary.
f16a58f14c/app/vmctl/influx/influx.go (L183-L186)
This pull request fix it by removing the check. For influx series
`measurement1_value1{}`, it will be represented as:
```go
Series{
Measurement: "measurement1",
Field: "value1",
LabelPairs: []LabelPair{},
EmptyTags: []string{},
}
```
and searched by the following query:
```sql
select "value1" from "measurement1"
```

https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7921
Commit 71bb9fc0d0 introduced a regression.
If labels are empty and relabeling is not configured, influx ingestion hanlder
performed an earlier exit due to TryPrepareLabels call.
Due micro-optimisations for this procotol, this check was not valid.
Since it didn't take in account metircName, which added later and skip metrics line.
This commit removes `TryPrepareLabel` function call from this path and inline it instead.
It properly track empty labels path.
Adds initial tests implementation for data ingestion protocols.
