-----------------------------------------

             Summary: 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
      Security Level: Public (Viewable by anyone)
    Affects Versions: 2.0
            Reporter: Alexei Scherbakov
            Priority: Major
             Fix For: 2.4


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.
