> Configurable rollback for long running transactions before partition exchange
> -----------------------------------------------------------------------------
>
> Key: IGNITE-6827
> URL: https://issues.apache.org/jira/browse/IGNITE-6827
> Project: Ignite
> Issue Type: Improvement
> Affects Versions: 2.0
> Reporter: Alexei Scherbakov
> Assignee: Alexei Scherbakov
> Priority: Major
> Fix For: 2.5
>
>
> Currently long running / buggy user transactions force partition exchange
> block on waiting for
> org.apache.ignite.internal.processors.cache.GridCacheSharedContext#partitionReleaseFuture,
> preventing all grid progress.
> I suggest introducing new global flag in TransactionConfiguration, like
> {{txRollbackTimeoutOnTopologyChange}}
> which will rollback exchange blocking transaction after the timeout.
> Still need to think what to do with other topology locking activities.
