Sowmya Ramesh commented on FALCON-325:
--------------------------------------
On the source cluster there already exists a relationship between Feed entity,
Source cluster and Feed Instance as shown below
FeedEntity <-(instance-of) FeedInstance (stored-in) -> Srccluster
When replication policy is run; edge with relationship label replicated-to has
to be added between FeedInstance and TargetCluster.
Also FeedInstance vertex property has to be updated with timestamp of
replication.
To improve the performance for the retrieval query : say get me all the
replicated instances for past 3 months
Add new REPLICATED property to FeedInstance vertex which was replicated. This
would avoid going and looking for out edge with label replicated-to to get the
replicated instances.
Please comment if you have any concerns about this approach. Thanks!
