Mircea Markus resolved ISPN-842.
--------------------------------
Resolution: Rejected
FirstAvailable functionality is already built in: all commands* extend
RetryOnFailureOperation, so if a command fails because the server goes down then the
command will be retried up to the moment again with the next available server. This
happens "clusterSize" times, so all the backend servers are tried before going
to the user.
Also none of the commands extending AbstractKeyOperation overrides the getTransport
method: and this method makes use of the configured load balancer.

---------------------------------------
Hmmm Mircea, I don't think you're understanding the meaning of first available.
This is about choosing a node and sticking to that one rather than doing round robin
around the cluster. I can't remember though the use case for this and forgot to add
the forum thread at the time, so let's leave it as it is. If I remember I'll
reopen.

Galder Zamarreño commented on ISPN-842:
---------------------------------------
Oh right, I remember the use case. It's the same as with HTTP sessions. The
FirstAvailable, or sticky load balance policy, would for a particular key chose a node,
and then all further requests for that key direct to the same node unless there's a
failure. This allows for replicated caches to be configured with async comms cos the
possibilities of landing on a different node to work on a key are reduced. I haven't
seen demand in the user forums, but something worth keeping in mind.

------------------------------------
Galder - thanks for updating this!
Two situations:
For distributed caches, after ISPN-530 a random node from the owners is chosen. One way to
do it is by always go to the main owner.
For replicated caches: we can implement the policy based on a CH function to consistently
choose the same node owner for the same key.
