Subject [jira] [Created] (IGNITE-11667) OPTIMISTIC REPEATEBLE_READ transactions does not guarantee transactional consistency in blinking node scenario

Dmitry Sherstobitov created IGNITE-11667:
--------------------------------------------

             Summary: OPTIMISTIC REPEATEBLE_READ transactions does not guarantee transactional
consistency in blinking node scenario
                 Key: IGNITE-11667
                 URL: https://issues.apache.org/jira/browse/IGNITE-11667
             Project: Ignite
          Issue Type: Bug
            Reporter: Dmitry Sherstobitov


Following scenario

Start cluster, load data
Start transactional loading (simple transfer task with PESSIMISTIC + OPTIMISTIC, REPEATABLE_READ
transactions)
repeat 10 times:
  Stop one node, sleep 10 seconds, start again
  Wait for finish rebalance (LocalNodeMovingPartitionsCount == 0 for each cache/cache_group)

Validate that there is no conflicts in sum of fields (verify action for transfer task)

In case of OPTIMISTIC/REPEATABLE_READ transactions there is no guarantee that transactional
consistence will be supported. (last validate step will be failed)
