Choose the database operation that preserves a proven change history and a usable recovery point. A running process or completed job is only one piece of evidence.
Review these lessons
- Replication slots: bound retained WAL before a consumer outage fills the disk
- CDC snapshot handoff: prove that initial rows and later changes form one history
- Transactional outbox: commit business state and event intent together
- Concurrent index builds: verify validity after the command exits
- DDL lock budget: fail a migration before it stalls production traffic
- Vacuum horizon: find transactions holding old row versions alive
- Partition retention: detach, prove the archive, then delete
- Point-in-time recovery: accept a restored timeline only after business reconciliation

Common Mistakes
- Do not equate connector activity with sink correctness.
- Do not call a restored server accepted before business reconciliation.
