Description

During the persistence of backing map entries into the backing map file, we create a new BackingMapEntry.Builder for each entry in the backing map. This can be optimised by using a single BackingMapEntry.Builder object and using it to build each entry during serialisation.

This Jira tracks the optimisation by avoiding multiple builder objects.

Thanks,
Janardhan
