InfluxDB 3 Core documentation

Comparing InfluxDB 3 products or planning a migration from InfluxDB 1 or 2? See Which InfluxDB 3 should I use? for a full decision guide.

InfluxDB 3 Core is a database built to collect, process, transform, and store event and time series data, and is ideal for use cases that require real-time ingest and fast query response times to build user interfaces, monitoring, and automation solutions.

Common use cases include:

  • Monitoring sensor data
  • Server monitoring
  • Application performance monitoring
  • Network monitoring
  • Financial market and trading analytics
  • Behavioral analytics

InfluxDB is optimized for scenarios where near real-time data monitoring is essential and queries need to return quickly to support user experiences such as dashboards and interactive user interfaces.

InfluxDB 3 Core is the InfluxDB 3 open source release.

Core’s feature highlights include:

  • Diskless architecture with object storage support (or local disk with no dependencies)
  • Fast query response times (under 10ms for last-value queries, or 30ms for distinct metadata)
  • Embedded Python VM for plugins and triggers
  • Parquet file persistence
  • Compatibility with InfluxDB 1.x and 2.x write APIs

Get started with InfluxDB 3 Core

The Enterprise version adds the following features to Core:

  • Historical query capability and single series indexing
  • High availability
  • Read replicas
  • Enhanced security (coming soon)
  • Row-level delete support (coming soon)
  • Integrated admin UI (coming soon)

InfluxDB OSS 2.9.0: API tokens are hashed by default

Stronger token security in InfluxDB OSS 2.9.0 — tokens are hashed on disk by default. Existing tokens are hashed on first startup and can’t be recovered afterward. Capture any plaintext tokens you still need before you upgrade.

View InfluxDB OSS 2.9.0 release notes

Hashed tokens authenticate exactly like unhashed tokens — clients and integrations keep working.

Also new in 2.9.0:

  • Configurable backup compression
  • Restore support for backups containing hashed tokens
  • Tighter Edge Data Replication queue validation
  • Flux upgrade
  • Compaction reliability improvements

  • --max-concurrent-queries: limit concurrent queries (adjustable at runtime).
  • GET /ready endpoint for readiness probes.
  • Processing engine: cross-database queries and trigger lockdown flags.

For more information, see the InfluxDB 3 Core release notes.

InfluxDB 3.10 is now available
