[JBoss JIRA] (ISPN-5021) Nodes that finish the rebalance later can see outdated values

We might need to do the same for our rebalance: start a rebalance with read_ch=old, write_ch=old+new, when the new owners have all the data install read_ch=new, write_ch=old+new, and finally read_ch=new, write_ch=new. Old cache entries are removed during the 2nd topology update, and further writes should be ignored, in order for this to work. -- This message was sent by Atlassian JIRA (v6.3.11#6341)

[JBoss JIRA] (ISPN-5019) After coordinator change, cache topologies should be installed in parallel

by Adrian Nistor (JIRA)

This is done on a single thread, and it can take a long time when there are a lot of caches. > We should be accelerate this by doing the topology installation on separate threads. However, we have to be careful with the async transport pool, because {{executeOnClusterAsync}} actually needs to spawn a new thread in the same pool. -- This message was sent by Atlassian JIRA (v6.3.11#6341)

[JBoss JIRA] (ISPN-5042) Remote gets caused by writes could be replicated only to the primary owner

Even though the latency of some write operations will be higher, the average latency should be better. -- This message was sent by Atlassian JIRA (v6.3.11#6341)

[JBoss JIRA] (ISPN-5046) PartitionHandling: split during commit can leave the cache inconsistent after merge

by Adrian Nistor (JIRA)

[ https://issues.jboss.org/browse/ISPN-5046?page=com.atlassian.jira.plugin.... ] Adrian Nistor updated ISPN-5046: -------------------------------- Fix Version/s: 7.2.0.Beta1 (was: 7.2.0.Alpha1) > PartitionHandling: split during commit can leave the cache inconsistent after merge > ----------------------------------------------------------------------------------- > > Key: ISPN-5046 > URL: https://issues.jboss.org/browse/ISPN-5046 > Project: Infinispan > Issue Type: Bug > Components: Core, State Transfer > Affects Versions: 7.0.2.Final, 7.1.0.Alpha1 > Reporter: Dan Berindei > Assignee: Dan Berindei > Priority: Critical > Fix For: 7.2.0.Beta1 > > > Say we have a cluster ABCD; a transaction T was started on A, with B as the primary owner and C the backup owner. B and C both acknowledge the prepare, and the network splits into AB and CD right before A sends the commit command. Eventually A suspects C and D, but the commit still succeeds on B before C and D are suspected. And SuspectExceptions are ignored for commit commands, so the user won't see any error. > However, C will eventually suspect A and B. When the CD cache topology is installed, it will roll back transaction T. After the merge, both partitions are in degraded mode, so we assume that they both have the latest data and the key is never updated on C. > From C's point of view, this is very similar to ISPN-3421. The fix should also be similar, we could delay the transaction rollback on C until we get a confirmation from B that T was not committed there. Since B is inaccessible, it will eventually get a SuspectException and the CD cache topology, at which point the cache is in degraded mode and it can wait for a merge. On merge, it should check the status of the transaction on B again, and either commit or rollback based on what B did. > We also need to suspend the cleanup of completed transactions while the cache is in degraded mode, otherwise C might not find T on B after the merge. -- This message was sent by Atlassian JIRA (v6.3.11#6341)
