Yes, that's exactly what we do: use the in-memory db until it comes time to save, and then we open a file db, attach, and copy it to disk. At that time, the journal files are created.
If there is a nice way to serialize an in-memory db to disk without having to open/attach to a file db, I'm all ears. Anyone know if this is possible?

I wonder if this might work: keep the database on disk, but when using it, always use it from an in-memory version. You could open an in-memory database, attach the on-disk version, and then copy all the data from the on-disk version to the in-memory version. Hmm. Unfortunately, I'm not sure how to copy the data back out to the on-disk version without the -journal file getting created, so maybe this isn't such a great idea after all. If it were possible to serialize the in-memory database as save it as a raw binary stream, then it might work. But I don't think there is a way to do that. ----------------------------------------------------------------------------- To unsubscribe, send email to [EMAIL PROTECTED] ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- To unsubscribe, send email to [EMAIL PROTECTED] -----------------------------------------------------------------------------
