    Description

      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.
