This works brilliantly, and the feature is built right in! This is more than what I was looking for. Thanks clueless newbie :)
I'm finally writing the tests for my app, and this works perfectly for testing, instead of copying a db file then removing it in each test file.
I keep all configuration inside of the db as well as the data (generated every five seconds), so I think what I'm going to do is have the config aspect in a separate db on disk, and the streaming data in memory which I back up with a timed event.
For those wondering, this is an application that gathers grow room environment information (temp, humidity so far, to also include water level, pH, EC/PPM etc for hydroponics, and soil moisture content data for soil) and writes it to what could be a volatile database. However, the configuration aspect of the system turns on/off electrical systems (lights, fans, humidifiers), so that part of the db must be reliably on disk, in case of a system crash/reboot, it needs to remember everything (timing, on/off configuration etc).
