InfluxDB 3 Core

InfluxDB 3 Core

Open source time series database for real-time events, analytics, and monitoring--powered by Apache Arrow, DataFusion, and Parquet.

License: MIT/Apache-2.0 Discord

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:

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:

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)

Other InfluxDB Versions

This repository contains multiple InfluxDB versions on separate branches:

Version Branch Query Languages Documentation
v3 Core (this branch) main SQL, InfluxQL docs.influxdata.com/influxdb3/core/
v2.x main-2.x Flux, InfluxQL docs.influxdata.com/influxdb/v2/
v1.x master-1.x InfluxQL, Flux docs.influxdata.com/influxdb/v1/

这是什么东西?InfluxDB 3 Core 是一个开源的时序数据库(time series database),用于采集、处理、转换和存储事件数据与时序数据。它用 Rust 编写,构建在 Apache Arrow、DataFusion 和 Parquet 之上。
它是我要部署的数据库服务器,还是嵌入到我应用里的库?它是一个独立的服务器,需要你自己部署,而不是一个库——你把它当作服务来运行,然后通过 8181 端口上的 HTTP API 与它通信。
它需要其他服务在运行吗,比如对象存储?不需要——它把 Parquet 文件直接保存到本地磁盘,零依赖;不过它也可以把数据写入 S3、Azure 或 GCP 上的对象存储。
大家通常用它来做什么?常见的使用场景包括传感器数据监控、服务器监控、应用性能监控、网络监控、金融市场和交易分析,以及行为分析。
v3 和我可能已经在用的 InfluxDB 2.x 有什么不同?查询引擎变了:v3 Core 支持 SQL(外加 FlightSQL 和 InfluxQL),而 2.x 分支用的是 Flux。v3 还是用 Rust 重写的版本,构建在 Apache Arrow、DataFusion 和 Parquet 之上。
它可以用于生产环境,还是仍处于实验阶段?它已经正式发布:InfluxDB 3 Core 于 2025 年 4 月达到 GA(正式可用),v3 标签下可以看到最新的发布说明。
