[JBoss JIRA] (ISPN-5600) Optimize transactions on multiple caches

by Radim Vansa (JIRA)

[ https://issues.jboss.org/browse/ISPN-5600?page=com.atlassian.jira.plugin.... ] Radim Vansa commented on ISPN-5600: ----------------------------------- I was looking to this for a while and started prototyping, but I've found that I would break interceptors that handle Prepare/Commit/Rollback commands since I would have to send them through the stack twice, and the code would get quite messy, too. I think that this cannot be implemented until we get explicit interceptor stack, that means 9.0 at best :-( > Optimize transactions on multiple caches > ---------------------------------------- > > Key: ISPN-5600 > URL: https://issues.jboss.org/browse/ISPN-5600 > Project: Infinispan > Issue Type: Enhancement > Components: Transactions > Affects Versions: 8.0.0.Alpha2 > Reporter: Radim Vansa > > NON_XA transactions that span multiple caches are registered as multiple synchronizations, and these synchronizations are often processed sequentially ^1^; therefore, we send synchronous PrepareCommand for each cache and then CommitCommand for each cache as well, delaying the commit by these round-trips. > Since the targets for different caches may differ, we still need to send the RPCs separately, but in parallel. Therefore, there should be one uber-synchronization for all caches that use NON_XA mode (and maybe something similar with XA). I believe that using single synchronization could save some allocations, too. > ^1^ Not sure if full-fledged JTA implementations do that; JTA spec does not say anything about the order of synchronizations and whether these should be processed in parallel. -- This message was sent by Atlassian JIRA (v6.3.15#6346)

[JBoss JIRA] (ISPN-3532) AsyncStore has only one live AsyncStoreProcessor (thread) in one time

[JBoss JIRA] (ISPN-5564) AsyncCacheWriter stop() and clear() should not wait for space in the modifications queue

[JBoss JIRA] (ISPN-5559) "AsyncCacheWriter is dead!" errors cause deadlock or unbounded use of memory

[JBoss JIRA] (ISPN-5563) AsyncCacheLoader.load() may still return stale data

[JBoss JIRA] (ISPN-5562) AsyncCacheWriter should write all data to the back-end store before shutting down

by RH Bugzilla Integration (JIRA)

This can primarily happen when writing the same keys in rapid succession. The coordinator thread will move these modifications to the head state (because of conflicts with tail), which is not checked before shutdown. > There are two other minor race conditions if stop() is called concurrently to write() or clear() - these cannot happen in practice because PassivationManager is stopped before PersistenceManager: > 1. AsyncStoreCoordinator checks State.stopped and State.modifications.isEmpty() without holding the readLock(). This is not reliable because a concurrent write() or remove() may still add to the modifications map. > 2. clear() just replaces the head state, without copying the stopped flag that may have been set by a concurrent stop(). -- This message was sent by Atlassian JIRA (v6.3.15#6346)
