We are using Export collections to bigquery firebase extension to export collections from Firestore to BigQuery. Everything is working fine except some documents are missing from the raw_changelog table. We could not find anything related to the missing documents in the logs either.
How can we identify using the logs that a particular document has not been exported to BigQuery? How to backfill the missing documents in the raw_changelog table once they are identified?
Note : This extension needs to be used for exporting data related to financial transactions. So, it needs to be reliable. Even a single missing document is problematic.
