gollark: The in-memory database is, however, really fast, it's fearlessly concurrent™, and it uses relatively high performance libraries.
gollark: For ease of implementation it uses an in-memory database which isn't hugely space-efficient. But I don't anticipate this using more than something like 10MB on Minoteaur-sized databases, and PHP/MW database backends (except SQLite) have more overhead than that anyway, as far as I know.
gollark: Plus, Minoteaur is much more resource-efficient, ish.
