Description
The AsyncBatchDestroyJob has been refactored to utilise Rails's
find_in_batches
method as opposed to a custom SQL query. This proves to make the process of record
deletion both more efficient and more resilient to database inconsistencies.
Previously, records that could not be deleted due to dependencies would raise an
exception, breaking the whole transaction. Now, these records are logged and
skipped over instead. Updates to associated tests have been made to verify and
reflect these changes.
