IIRC Sanjeewa was working on this. > Azeez, sumedha senaka and me had discussion on same topic sometimes back. Our problem was replicating cache in domains and sub domains separately. We came up with idea of having one active master and slave slave nodes per each sub domain and sub domain. Once cache is modified all nodes will inform to master node then master will take care of informing that to all nodes. AFAIK no body was working on this and we decided to suggest this for next kernel level release. @Azeez, sumedha please add if i missed anything.
