Do all the delete in batch of 1k all in the DB.
Rather than fetch a list of IDs and generate a big
IN
delete query, we can just do it with a sub query and a LIMIT.On MySQL specifically directly do a
DELETE ... LIMIT
, but SQLite and PG don't support that syntax so we use aDELETE FROM (SELECT id .. LIMIT)
instead.
