Pull request overview
Adds database indexes on BulkOperationTask timestamp/status columns to improve performance for bulk operation history queries (notably ORDER BY created DESC, and WHERE status=... ORDER BY created DESC) and reduce DB sort memory pressure.
Changes:
- Added an index on
created(descending) for faster default ordering by newest tasks. - Added a composite index on
(status, created DESC)to accelerate status-filtered history queries ordered by newest first. - Introduced a Django migration to apply these indexes at the database level.
