This adds a set of magical environment variables that can be used to tweak the database parameters. It's totally undocumented and not intended to be a long term or supported thing. It's ugly, but there is a backstory. I have a couple of large installations where the database options are inefficient or otherwise suboptimal (24/7 compaction going on and stuff like that). I don't *know* the correct database parameters, nor yet the formula or method to derive them by, so this requires experimentation. Experimentation needs to happen partly in production, and rolling out new builds for every tweak isn't practical. This provides override points for all reasonable values, while not changing anything by default. Ideally, at the end of such experimentation, we'll know which values are relevant to change and in what manner, and can provide a more user friendly knob to do so - or do it automatically based on the database size. |
