Retention policy

TSDB

-retentionPeriod=30d by default. Changed on the TSDB, not in the Unimoni cabinet (via docker-compose / a systemd unit).

Postgres

• audit_log — append-only, we recommend archiving to S3 after 1 year
• alert_incidents — state='resolved' older than 90 days can be archived periodically
• sessions — auto-cleanup of expired ones via cron

Cleanup cron

DELETE FROM sessions WHERE expires_at < now() - INTERVAL '7 days';
DELETE FROM passkey_sessions WHERE expires_at < now() - INTERVAL '1 day';
DELETE FROM email_verification_tokens WHERE expires_at < now() - INTERVAL '7 days';

We run it nightly.
