The short version

  • Only TimescaleDB has a free tier, so it costs nothing to try first.
  • Each has a real cost: Datadog Logs complex, multi-tiered pricing model based on ingestion, indexing, and storage; can become expensive at scale; TimescaleDB inherits PostgreSQL write path limitations, creating a ceiling on ingestion throughput
  • They diverge on capability: Datadog Logs covers Log ingestion, TimescaleDB covers Time-series Optimization.
