Story #3474
Maintain consistency across CN hazelcast backing datastores
0%
Description
Story to capture work needed ensure data consistency across CN datastores.
Due to partition tolerance of the distributed cache (hazelcast), it is possible for the storage datastore to become inconsistent across CN when create/update/deletes are performed in one cluster partition and not synchronized across the cluster when the partitions in the cluster are resolved/joined.

- Status changed from New to Rejected
Due to the larger architectural scope of the consistency issues with Hazelcast over WAN, a custom merge policy within hazelcast won't provide a complete fix. I'm rejecting this in favor of an architectural refactor that will be described in other tickets.
