[infinispan-issues] [JBoss JIRA] (ISPN-3793) L1 tracks requestors for nodes that don't retrieve a value

L1 tracks requestors for nodes that don't retrieve a value ---------------------------------------------------------- Key: ISPN-3793 URL: https://issues.jboss.org/browse/ISPN-3793 Project: Infinispan Issue Type: Bug Components: Distributed Cache Affects Versions: 6.0.0.Final Reporter: William Burns Assignee: William Burns Currently we always register any non local requestor in the L1 requestors map. This can be a performance issue with values that aren't present in the cache, since a new value put in for that value will require invalidating those nodes in addition to storing the key in memory while waiting for that. The easiest fix would have been to check the command invocation to see if it returns a value, however ISPN-3737 moved the registering to before the command is ran to prevent a different issue. Also thinking about it we could remove the requestor after the command returns, however this also has a race condition if you had data committed and the node retrieved the value concurrently.
