Scaling & retention

avuru obs stores every signal in ClickHouse, so capacity planning is mostly ClickHouse planning — one engine to size instead of four.

  • Sizing — driven by ingest rate (spans/s, metric points/s) and retention.
  • Retention — TTL per signal table.
  • Sharding — for high-volume clusters.

:::note This page is expanding Concrete sizing tables and TTL examples are being added. :::
