Darrel Schneider updated GEODE-9757:
------------------------------------
    Description: 
If you do a non-tx put directly on a member of a geode cluster (for example 
using a geode function), then the value is stored in the pr locally in a 
CachedDeserializable. But if you do the same op in a transaction it will store 
the object directly in the pr with no CachedDeserializable.

I think the reason for this is that the original tx implementation did not 
support partitioned regions and on a non-pr region the local region stored the 
value directly. So when support was added for transactions on partitioned 
regions this part of the code was not customized for partitions and just used 
the old code.

This can cause extra work to be done when fetching a value from the pr to send 
it back to a client. It can also cause bucket size exceptions if you directly 
change the value stored. 

A workaround to the bucket size exceptions is to make a copy of the value 
before changing it.
