This is follow-up for c5713a09d3
Originally, dateMetricID cache was fully rotate every 20 minutes. It
made daily-index pre-creation less efficient and caused CPU usage spikes
for index records lookup at midnight.
storage pre-fills index records for the next day in 1 hour before night.
But this rotation made only last 20 minutes before midnight visible in
the cache.
This commit changes rotation period from 20 minutes to 2 hours ( 1 hour
tick interval). While
it could slighlty increase cache memory usage ( in practice it shouldn't
be noticeable). It prevents from CPU usage spikes.

VictoriaMetrics
VictoriaMetrics is a fast, cost-saving, and scalable solution for monitoring and managing time series data. It delivers high performance and reliability, making it an ideal choice for businesses of all sizes.
Here are some resources and information about VictoriaMetrics:
- Documentation: docs.victoriametrics.com
- Case studies: Grammarly, Roblox, Wix,....
- Available: Binary releases, docker images Docker Hub and Quay, Source code
- Deployment types: Single-node version, Cluster version, and Enterprise version
- Changelog: CHANGELOG, and How to upgrade
- Community: Slack, X (Twitter), LinkedIn, YouTube
Yes, we open-source both the single-node VictoriaMetrics and the cluster version.
Prominent features
VictoriaMetrics is optimized for timeseries data, even when old time series are constantly replaced by new ones at a high rate, it offers a lot of features:
- Long-term storage for Prometheus or as a drop-in replacement for Prometheus and Graphite in Grafana.
- Powerful stream aggregation: Can be used as a StatsD alternative.
- Ideal for big data: Works well with large amounts of time series data from APM, Kubernetes, IoT sensors, connected cars, industrial telemetry, financial data and various Enterprise workloads.
- Query language: Supports both PromQL and the more performant MetricsQL.
- Easy to setup: No dependencies, single small binary, configuration through command-line flags, but the default is also fine-tuned; backup and restore with instant snapshots.
- Global query view: Multiple Prometheus instances or any other data sources may ingest data into VictoriaMetrics and queried via a single query.
- Various Protocols: Support metric scraping, ingestion and backfilling in various protocol.
- Prometheus exporters, Prometheus remote write API, Prometheus exposition format.
- InfluxDB line protocol over HTTP, TCP and UDP.
- Graphite plaintext protocol with tags.
- OpenTSDB put message.
- HTTP OpenTSDB /api/put requests.
- JSON line format.
- Arbitrary CSV data.
- Native binary format.
- DataDog agent or DogStatsD.
- NewRelic infrastructure agent.
- OpenTelemetry metrics format.
- NFS-based storages: Supports storing data on NFS-based storages such as Amazon EFS, Google Filestore.
- And many other features such as metrics relabeling, cardinality limiter, etc.
Enterprise version
In addition, the Enterprise version includes extra features:
- Anomaly detection: Automation and simplification of your alerting rules, covering complex anomalies found in metrics data.
- Backup automation: Automates regular backup procedures.
- Multiple retentions: Reducing storage costs by specifying different retentions for different datasets.
- Downsampling: Reducing storage costs and increasing performance for queries over historical data.
- Stable releases with long-term support lines (LTS).
- Comprehensive support: First-class consulting, feature requests and technical support provided by the core VictoriaMetrics dev team.
- Many other features, which you can read about on the Enterprise page.
Contact us if you need enterprise support for VictoriaMetrics. Or you can request a free trial license here, downloaded Enterprise binaries are available at Github Releases.
We strictly apply security measures in everything we do. VictoriaMetrics has achieved security certifications for Database Software Development and Software-Based Monitoring Services. See Security page for more details.
Benchmarks
Some good benchmarks VictoriaMetrics achieved:
- Minimal memory footprint: handling millions of unique timeseries with 10x less RAM than InfluxDB, up to 7x less RAM than Prometheus, Thanos or Cortex.
- Highly scalable and performance for data ingestion and querying, 20x outperforms InfluxDB and TimescaleDB.
- High data compression: 70x more data points may be stored into limited storage than TimescaleDB, 7x less storage space is required than Prometheus, Thanos or Cortex.
- Reducing storage costs: 10x more effective than Graphite according to the Grammarly case study.
- A single-node VictoriaMetrics can replace medium-sized clusters built with competing solutions such as Thanos, M3DB, Cortex, InfluxDB or TimescaleDB. See VictoriaMetrics vs Thanos, Measuring vertical scalability, Remote write storage wars - PromCon 2019.
- Optimized for storage: Works well with high-latency IO and low IOPS (HDD and network storage in AWS, Google Cloud, Microsoft Azure, etc.).
