IS THERE A WAY TO RECOVER CDC RESTAURING SOMEFILE FROM BACKUP? DONT WANT TO FULL LOAD AGAIN

Based on the knowledge sources available, there is no documented method in Airbyte for recovering CDC by restoring a backup file to avoid a full reload. Here's what the knowledge sources do say about your situation: Options When CDC Position Is Lost When a CDC position becomes invalid (e.g., due to WAL recycling or log expiration), Airbyte offers two behaviors via the Invalid CDC Position Behavior setting: 1. Re-sync Data (Automatic Recovery): Automatically triggers a full refresh/re-snapshot of the entire database. 2. Fail Sync (Manual Intervention): Stops the sync and marks it as failed, allowing you to investigate before taking action. [CDC best practices] Neither option involves restoring from a backup file. Editing Connection State (Limited Workaround) You can manually edit the connection state in the Airbyte UI (Settings → Advanced → Connection State) to adjust the cursor position for incremental syncs. This could theoretically help you resume from a specific point in time. However: • This is only for cursor-based incremental syncs, not necessarily CDC WAL/LSN positions. • The docs warn: "Updates to connection state should be handled with extreme care. Updates may break your syncs, requiring a full historical sync of your data to fix. Make changes only as directed by the Airbyte team." [manage connection state] Skipping the Initial Snapshot (Feature Request, Not Yet Available) There is an open GitHub issue requesting the ability to skip the initial snapshot and start CDC from a current WAL LSN (after preloading data externally). This feature does not currently exist in Airbyte — it has been escalated internally but is not yet implemented. [Postgres CDC issue] Summary Unfortunately, the knowledge sources do not describe a supported way to recover CDC from a backup file to avoid a full reload. Your best options are: • Manually edit the connection state (with caution and ideally with Airbyte team guidance). • Contact Airbyte support if you are on Cloud, as they may be able to assist with state manipulation. • Accept the full re-snapshot if the CDC position is truly lost. 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.
