> This would mean we could move back to fetching Ids in the same transaction as the main writes (so the id claim would also be rolled back on failure). > But as long as we are okay having some skipped IDs I would propose not touching it more now, they are after all, only numbers! I am strongly against doing so in one transaction. Previously this results in database lock timeout, and this may be exploited by anyone without being detected (i.e. a strong DoS potential).
