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. :::
