Backfill and Sync Reliability Issues with Estuary → Tinybird Pipeline

[ronak-89]

We are facing intermittent syncing issues between Supabase → Estuary Collections → Tinybird.

For some tables, Estuary does not automatically backfill historical data, so we have to trigger manual backfills. However, manual backfills also frequently fail or get stuck.

The strange part is:

• Updates from Supabase are successfully reaching the Estuary collection.
• But data is not syncing from the collection to Tinybird.
• We have tried deleting/recreating the datasource, re-running source and destination backfills, and multiple manual retries, but the issue keeps recurring.
• Sometimes syncing randomly starts working again after retries, but later stops again unexpectedly.

This is causing unreliable syncing and repeated manual intervention. Could you please help investigate why collection → Tinybird syncing and backfills are intermittently failing?
