[infinispan-issues] [JBoss JIRA] (ISPN-7672) NonTotalOrderTxPerCacheInboundInvocationHandler throws warning when adding cache entry using Spring Session

[Galder Zamarreño (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-7672?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13384798#comment-13384798 ] 

Galder Zamarreño commented on ISPN-7672:
----------------------------------------

Hmmmm, why would the server be configured with optimistic transactional caches? The client has no method to start a transaction or batch and then commit it, so taking in account each possible (implicit) transaction right now would contain just one operation within it, what would be the sense of using optimistic transactions?

Optimistic transactions are normally used to avoid locking a key for the duration of the tx and instead relying on version checks at the end of the transaction. With HR, since only a single operation can be part of the tx, I hardly see much benefit to using optimistic locking since the lock duration would be the minimal it can be.

Am I missing something?

> This didn't happen in {{CR2}} release, so there must be something that changed since then. I also noticed that this sometimes leads to exceptions in the Hot Rod client.
