Thanks, Larry. I can only imagine the unspeakable things developers attempt to do to SQLite and what you hear about on the forum. I should have prefaced my question by saying that it was for an experiment. I'd love some feedback on the replication tool. I'm open-sourcing it in the next few days. It's still beta software but it seems to be running well so far. Since it's doing physical replication, I'm able to periodically validate the replication by checksumming the primary database & restoring and checksumming the replica. It seems to be a good check for correctness. It's certainly not hardened enough to be production-ready but it's probably ok for a personal project—so long as you're not building nuclear-armed missile launch software in your spare time. Ben
