Jaeger is an open-source solution for troubleshooting cloud-native applications using distributed tracing. It's a Cloud Native Computing Foundation project that's widely adopted alongside Prometheus to monitor applications running in Kubernetes. Jaeger supports various storage backends, including Elasticsearch and Cassandra, but also offers PostgreSQL as a certified durable, reliable, and scalable storage option. Promscale is a unified metric and trace storage for Prometheus, Jaeger, and OpenTelemetry built on PostgreSQL and TimescaleDB. The integration allows Jaeger to use PostgreSQL as a storage backend with full support for Jaeger's features, including Service Performance Management. This enables engineers to analyze traces using SQL query capabilities and build dashboards in Grafana. With Promscale, the Jaeger community can now confidently use a well-known database to store their traces, unlocking new capabilities and improving the overall observability of cloud-native applications.
