We use the Firestore to BigQuery export extension to export analytics data (that our clients write to Firestore) to BigQuery. After that we no longer need the data in Firestore, so we'd like to add a ttl to the collection. But if we delete a document, the extension will write an additional row to BigQuery, which increases our query cost (or complexity).

For that reason it'd be great if the extension had an option to not process document deletions.
