- this code suffers from two problems:
- when we don't have any new settings to insert, we still end up
fetching the columnInfo and owner info, even though we only need
them if we're inserting data. This results in 3 extra queries upon
boot
- secondly, we insert every setting with a separate query - MySQL and
SQLite both support batch inserts and knex has a utility to help us
that I've [used
before](38821c5242).
With 95 settings at the time of writing, this adds 94 extra queries
during the DB init
- this commit refactors the code so that we only fetch the columnInfo and
owner data if we've got new settings to insert, and batches the
inserts using knex's batchInsert util
- this query results in ~95 less queries during DB init and saves a
couple of queries during boot
