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)
