Overview

InfluxDB 3 Core is a time series database written in Rust on Apache Arrow and DataFusion. It ingests line protocol, persists data as Parquet on object storage (S3, Azure, GCP) or local disk, and answers SQL, InfluxQL or Flight SQL queries over HTTP on port 8181. It also embeds a Python VM for plugins and triggers.

Who it is for: Engineers storing metrics, sensor or event data who want SQL over Parquet

Strengths

  • Runs on local disk with no dependencies, or on S3, Azure or GCP object storage
  • Accepts InfluxDB 1.x and 2.x write APIs and the 1.x InfluxQL query API
  • Embedded Python VM for plugins and triggers
  • Data persisted as open Parquet files, queryable via SQL, InfluxQL and Flight SQL

Weaknesses

  • Flux is not supported on this branch; it exists only in the v2.x and v1.x branches
  • A separate InfluxDB 3 Enterprise edition exists; README does not list the feature differences
  • Not an AI project; fits this list only as a general-purpose backend
  • Other InfluxDB versions live on separate branches, so the main branch covers v3 only

What it needs

  • no GPU
  • Docker
  • port 8181
