Judgement

What it is

Building block

What it does

A time-series database for metrics, events and sensor data, rewritten in Rust for version 3 with SQL queries and Parquet storage.

Adopt it when

You collect large volumes of time-stamped data such as IoT or monitoring metrics.

Watch out

Version 3 broke compatibility with earlier query languages, and the open-source Core edition limits features sold in Enterprise.

Ready for

Production-ready

Runs as

Self-hosted server and cloud service

Built with

Rust, Apache Arrow and Parquet

How established
