 Another way of controlling the size of the long-term database is setting a maximum age for log queries to keep using the config parameter [`MAXDBDAYS`](configfile.md#maxdbdays). It defaults to 365 days, i.e. queries that are older than one year get periodically removed to limit the growth of the long-term database file.
