Migration Notice
We're migrating documentation from the old portal into this one. Some things may look a little different or out of place in the meantime — we know, and we're working to get it right. If something's unclear or doesn't look right, let us know.

Advanced Settings

The Advanced Settings tab controls ClickHouse retention, the time-to-live (TTL) windows for the highest-volume analytics data.

ClickHouse Retention​

ClickHouse drops rows older than the configured window on its next merge pass, so there is no cleanup job to run. A saved value applies immediately without a console restart.

Lower a value if you are short on disk space. Raise it to meet legal, compliance, or eDiscovery retention requirements.

SettingData coveredDefaultRange

Guidance​

  • Storage audit events — the Apply Retention button on the Database tab uses this same value.
  • Pipeline logs — the flyout shows at most 7 days. A longer window wastes disk space on lines the interface cannot display. A shorter window limits the time range you can select.
  • K8s audit events — small clusters can reduce the window to 90 days. Large multi-cluster fleets that keep a two-year audit trail can extend it to 730 days.
  • Analyzer results — this single setting governs all three analyzer outputs. These records feed the data risk score and the file-level audit trail, and are the evidence behind compliance findings. Shorten the window with caution.
