Promscale is a unified metrics and traces observability backend for Prometheus, Jaeger, and OpenTelemetry, built on PostgreSQL and TimescaleDB. It acts as a PromQL-compliant Prometheus remote storage and a certified Jaeger trace storage backend, but has been officially discontinued and is no longer maintained.

Use cases

• store prometheus metrics long-term in postgresql
• use postgres as a jaeger trace storage backend
• query metrics and traces together with promql
• self-host a unified observability backend for metrics and traces
• run prometheus remote read/write against timescaledb
• correlate traces and metrics in grafana

When to choose

• you are already invested in promscale and need reference material for an existing deployment
• you need a postgres/timescaledb-based observability backend and are willing to maintain a fork yourself

When to avoid

• starting any new observability project - the project is officially deprecated and unmaintained
• you need supported prometheus long-term storage - use alternatives like Mimir, Thanos, or Cortex
• you need a supported jaeger storage backend - use the officially supported options
• you expect upstream fixes, security patches, or community support
