> Components: mvcc
> Reporter: Vladimir Ozerov
> Assignee: Ivan Pavlukhin

>
> Deadlocks are not uncommon during SQL execution.
> We need to implement distributed deadlock detection protocol for MVCC.
> Essentially, nodes should exchange some map of tx wait lists, and try to find
> a loop. If loop is found, then one of problematic transactions should be
> rolled back.
