Alexey Goncharuk commented on IGNITE-2854:
------------------------------------------
The approach sounds good. However, I would leave the option to automatically
rollback the oldest transaction in a deadlock to be configured - in some cases
it makes sense to only rollback such transactions from a management tool.

> 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: Andrey Gura
> 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.
