Thank you for releasing this fix in v4.2.2. I was able to deploy this change in PTF's kcp1 env https://pre-kiwi-cap1.int.aws.folio.org/
Following are the result for v4.2.2 after running a few tests against the export of 100K instances:
On average, Data export takes 51 minutes for 100K for items and holdings job profile which is around 15 minutes faster than previous release
Consumes around 50% less CPU than previous release
Before:
After:
Memory is stable around 120%
mod-data-export logged 322K log messages vs 42 Million log messages for 100K export
Before
After
Total memory used by unreferenced JVM Garbage Collector reduced by 11%. Complete JXRay Report for reference:

After
Overall, this is a good performance improvement compared to the previous release.

I've updated it to Awaiting deployment as it was included into Kiwi Bugfix Release.
We should reopen in case verification fails.

Currently we don't have a spare Kiwi env to verify this ticket. Once we are freed up with DI testing in Kiwi we can get back to this.
