[JBoss JIRA] (ISPN-4903) ServerFailureRetrySingleOwnerTest doesn't actually test client retry

[JBoss JIRA] (ISPN-5083) Hot Rod decoder should use async Cache operations

Instead, Hot Rod decoder should call up async operations, convert the Notifying Futures to Scala Futures, and write up the reply when it's received.

[JBoss JIRA] (ISPN-5093) Granularity of remote event listener implementations doing the same job

by Gustavo Fernandes (JIRA)

[ https://issues.jboss.org/browse/ISPN-5093?page=com.atlassian.jira.plugin.... ] Gustavo Fernandes updated ISPN-5093: ------------------------------------ Fix Version/s: 8.2.0.Final (was: 8.2.0.CR1) > Granularity of remote event listener implementations doing the same job > ----------------------------------------------------------------------- > > Key: ISPN-5093 > URL: https://issues.jboss.org/browse/ISPN-5093 > Project: Infinispan > Issue Type: Enhancement > Components: Remote Protocols > Reporter: Galder Zamarreño > Assignee: Galder Zamarreño > Fix For: 8.2.0.Final > > > Currently, if N clients add the same listener to a cache that does the same job, e.g. keeping a near cache consistent, this results in N server-side cluster listeners created, each potentially installed in different nodes. If one of those nodes fails, all clients that had a listener registered to that node will have to find a different node for this listener. > The downsides of this approach is that there are as many cluster listeners installed as clients have added listeners (or have near cache enabled), which might not very efficient. If a node goes down, all clients that have cluster listeners there need to failover to some other node. > The advantage of this approach is simplicity of the approach to decide where to add the listener and where to failover to. > For this type of scenarios, an alternative set up might be worth exploring: > If all these client side listeners are interested in exactly the same events, and the client ID would be exposed via the RemoteCache API, a server side cluster listener multi-plexing between all these clients could be potentially built. In other words, instead of having N clients register N cluster listeners, the first client would register the cluster listener with a client listener ID, and if more registrations were added with the same client listener ID, the connections would be added to the existing cluster listener implementation. > The maximise the efficiency of this solution, all clients (even running in different JMVs), given the same client listener ID, should agree upon the node to add the listener in. For a distributed cache, hashing on the cache name would work. For replicated caches, since there's no hashing available, the first node of the view could be used. > Since the logic to be executed server-side varies between being the first node adding the client listener vs the others, synchronization would be added to make sure that the first invocation only creates the cluster listener, and the others simply add the channel to the listener. > Failover is a bit more tricky too, because if the node with the cluster listener goes down, all the clients have to failover, which again exposes a 1st vs the others type of logic. > Advantages of this approach is the reduction in number of cluster listeners and potentially efficiency coming from a single cluster listener implementation server side. > The disadvantages come from the server side logic to add/failover a cluster listener, which need to take into account if the listener is present or not. Other disadvantages come from needing the clients to use some specific routing for adding listeners for same node. -- This message was sent by Atlassian JIRA (v6.4.11#64026)

[JBoss JIRA] (ISPN-5077) Custom remote events can be slightly inefficient
