             Summary: Need to implement deadlock detection
                 Key: IGNITE-2854
                 URL: https://issues.apache.org/jira/browse/IGNITE-2854
             Project: Ignite
          Issue Type: New Feature
          Components: cache
    Affects Versions: 1.5.0.final
            Reporter: Valentin Kulichenko
            Assignee: Valentin Kulichenko
             Fix For: 1.6


Currently, if transactional deadlock occurred, there is no easy way to find out 
which locks were reordered.

We need to add a mechanism that will collect information about awating 
candidates, analyze it and show guilty keys. Most likely this should be 
implemented with the help of custom discovery message.

In addition we should automatically execute this mechanism if transaction times 
out and add information to timeout exception.
