[jira] [Updated] (GOSSIP-88) Data Replication Control

     [ https://issues.apache.org/jira/browse/GOSSIP-88?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mirage Abeysekara updated GOSSIP-88:
------------------------------------
    Description: 
Currently shared data and per node data get replicated on all nodes. It is better to have data replication control with following requirements

* Data should never get replicated
* Data should only get replicated on given set of nodes
* Data should only replicated on its Datacenter

In implementation the AbstractActiveGossiper is currently sending its shared data and per node data to a randomly selected live member. To control this replication we add a new property to the message (eg: SharedDataMessage  has a property which says whether this datum need to be replicated or not with a given member.) and use that property in the AbstractActiveGossiper when sending data to a member.
