> 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
