[infinispan-issues] [JBoss JIRA] (ISPN-1556) Ability to test and acquire lock if available, without aborting the txn if not available

Ability to test and acquire lock if available, without aborting the txn if not available ---------------------------------------------------------------------------------------- Key: ISPN-1556 URL: https://issues.jboss.org/browse/ISPN-1556 Project: Infinispan Issue Type: Feature Request Affects Versions: 5.1.0.BETA2 Environment: AS7.1.0.alpha2 Reporter: Gary Brown Assignee: Galder Zamarreño Attachments: CacheTxStackTrace.log, Sample2Test.java, SampleTest.java, serverISPNTrace.log.zip I have a system that performs a large number of tasks in a single transaction for efficiency. Some of those tasks access infinispan caches. I found that occasionally I have been getting lock timeouts for the default 15 second period. Lock contention is not a problem - but the impact of failing to obtain the lock results in the whole transaction being aborted, which aborts the work also carried out for potentially a large number of other tasks, resulting in all of the work being retried. I was wondering if it would be possible to provide an alternative lock implementation the AdvancedCache that allowed a client app to test whether the lock was available and acquire it - returning 'true', but if the lock was not available, simply returning false, allowing the client code to make a decision about how to proceed. In my case, I could then add the specific task to a retry queue, and move onto the next task, committing all of the work that had been successfully completed for the other tasks.
