no issue
- When bulk insert fails there is no transactional logic to revert
related records form being inserted. Also, previously there were no
attempts to "retry" the insert.
- To avoid complex retry logic, an iterative one-by-one insert retry
approach was taken. If this becomes a bottleneck in the future, the
retry algorithm could be improved.
- To avoid a lot of code duplication refactored model's `bulkAdd` & `bulkDestroy`
methods to use 'bulk-operations' module.
- Updated error handling and logging for bulk delete operations. It's very
unlikely for error to happen here, but still need to make sure there is
a proper logging in place to trace back the failure.
- Added debug logs. This should improve debugging experience and
performance measurements.
- Added handling for unrecognized errors. Handling inspired by current unrecognized
error handling by ghost importer -10e5d5f3d4/core/server/data/importer/importers/data/base.js (L148-L154)
