Hi All, I am currently working on the issue Redmine-3207[1]. *Issue:* With the current notification impl, each node cache needs to sync with every others. So when the particular resource updated, it gets the all subscription keys from its cache and send notifications.
With the distributed cache, each node does not have all records(subscriptions) synced in its cache. records are distributed among the nodes. So our above implementation fails, because we cannot retrieve all record from the working node. *Proposed Solution: * As offline chat with Azeez, We came up with the solution of sending a cluster message with the instruction and the node which actually having the record, perform the instruction on behalf of the working node. *Problem with the solution:* One particular record can exists in multiple nodes. So when the working node send a cluster message, every other node having that record gets triggered and perform the instruction. In this case, all these nodes send notification and we get multiple notifications for the resource update. This is happen because each time when server get restart, it loads all subscriptions from the subscription manager(db). Is there way of distribute records among nodes when loading subscriptions from the manager?
