Ivan Pavlukhin commented on IGNITE-10183:
-----------------------------------------
[~rkondakov] I have on comment for the patch. Is it important that only one key
is used in tests? Can we use different keys in order to avoid possible write
conflicts? It will allow us to keep test without code needed for MVCC only.
> [Test Failed] IgniteClientReconnectCacheTest.testReconnectOperationInProgress
> flaky fails on TC.

> Test invokes cache put/get from client node and at the same time forces
> client to disconnect.
> With {{ATOMIC}} and {{TRANSACTIONAL}} atomicity mode when client disconnects
> it cancels all futures with exception
> {{IgniteClientDisconnectedCheckedException}} (for example, see
> {{GridCacheMvccManager#onDisconnected}}).
> It seems that for the TRANSACTIONAL_SNAPSHOT mode, similar logic should be
> implemented.
