[infinispan-issues] [JBoss JIRA] (ISPN-2392) Optimize locking behaviour in non-transactional caches

[Mircea Markus (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-2392?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12742250#comment-12742250 ] 

Mircea Markus commented on ISPN-2392:
-------------------------------------

ISPN-2552 solved this problem for distributed caches. For replicated caches you can use a degenerated cache of distributed caches by setting numOwners to a very high value(e.g. 10000 given that your cluster doesn't have that many nodes).

> Situation: REPL_SYNC cache, non transactional, locking isolation level NONE
> Problem: when multiple threads trying to write same key on multiple nodes, the operation ends up mostly in locking timeouts
> Mircea mentioned that the locking behaviour for non-tx caches could be optimized as well as for tx-caches or use the same mechanisms.
> (One single lock, independed number of owners)
