</div>

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)
