HTTP 409 · Do not retry unchanged — fix the request first
The snapshot or change cursor has expired.
What happened
Snapshots expire after one hour. Changes older than seven days are no longer available through the bounded change feed.
How to fix it
- Open a new snapshot with a new request_id, apply all pages to a separate local view, then continue using its delta_cursor.
- Keep your existing local view until the complete replacement is ready.
Retrying
Repeating the request unchanged will fail again. Correct the request first — the response tells you which part is wrong.
