The short version

  • Each has a real cost: PostgreSQL requires manual scaling across multiple machines for very large deployments; Zipkin less active development and smaller community momentum than Jaeger
  • They diverge on capability: PostgreSQL covers ACID Compliance, Zipkin covers Trace collection and search.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

PostgreSQL

  • Requires manual scaling across multiple machines for very large deployments
  • Performance tuning requires deep knowledge of database internals
  • No built-in graphical admin interface; command-line tools are primary method

Zipkin

  • Less active development and smaller community momentum than Jaeger
  • Fewer features: sampling, storage options and UI are all more limited
  • The interface is dated and slower to work with on large trace volumes
  • Tracing alone still leaves metrics and logs in separate tools during an incident
