Scalable datastore for metrics, events, and real-time analytics
cargo add influxdbInfluxDB 3 Core
Open source time series database for real-time events, analytics, and monitoring--powered by Apache Arrow, DataFusion, and Parquet.
InfluxDB 3 Core is a database built to collect, process, transform, and store event and time series data. It 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’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
- Compatibility with InfluxDB 1.x query API (InfluxQL)
- SQL query engine with support for FlightSQL and HTTP query API
Storage format: Apache Parquet on object storage (S3, Azure, GCP) or local disk
Query languages: SQL, InfluxQL, Flight SQL
Write format: Line protocol
API: HTTP on port 8181
Built with: Rust, Apache Arrow, DataFusion
Compatible with: InfluxDB 1.x and 2.x write APIs, InfluxDB 1.x query API (InfluxQL)
