Hehe, yes, I took the shotgun approach. The MySQL lists don't seem to be quite as active, and the MySQL forum moderators seem to take about 1-2 days before they approve my posts. Hmm... thanks for pointing that out about system metadata caching. I'll have the solve the problem of MariaDB thinking

I see... so the MariaDB top-half (by "top-half" I mean everything that sits above the storage engine) doesn't do nasty things like caching? If it did, then writes at other MariaDB sites wouldn't show up in reads performed at the site caching the data. If the MariaDB top-half does nothing more than
