Summary: MVCC: implement deadlock detector
Key: IGNITE-9322
URL: https://issues.apache.org/jira/browse/IGNITE-9322
Project: Ignite
Issue Type: Task
Components: mvcc
Reporter: Vladimir Ozerov
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.
