Avoid large sql "in" clauses by operating on smaller batches of stacks at a time. To avoid transaction overhead and contention on the resource table, the first deletions occur outside of a transaction (are autocommitted). This is OK because the purge is re-rentrant -- we won't lose any stack_id's to delete if something goes wrong before the conn.begin() block. That is, we will not orphan any rows if the purge is run multiple times where an error occurs. Change-Id: I9edf0558ed54820842193560e323df6501411d1d |
