## What it is
Apache HoraeDB (incubating) was a high-performance, distributed, cloud-native time-series database written in Rust, supporting workloads like IoT metrics and Prometheus remote storage. The Apache Incubator podling was retired on 2026-03-03, and the main branch was in unstable rapid development toward a new metric engine.

## Use cases
- store and query time-series metrics at scale
- use as Prometheus remote storage backend
- run a cloud-native distributed TSDB for IoT sensor data
- self-host a Rust-based time-series database
- horizontally scale time-series ingestion and analytics

## When to choose
- you need a stable legacy release from the analytic-engine branch and accept an inactive project
- you want to study or fork a Rust distributed TSDB design

## When to avoid
- you need a maintained, supported time-series database - the Apache podling retired in March 2026
- you want production stability from the main branch, which was explicitly unstable
- you need long-term community support or guaranteed releases

## Facets
- artifact type: service
- maturity: abandoned
- function: database, monitoring
- domain: databases, iot, monitoring, cloud-computing
- platform: rust, cloud, self-hosted
