["Anton Vinogradov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-1525?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15424305#comment-15424305 ] 

Anton Vinogradov commented on IGNITE-1525:
------------------------------------------

According to face-to-face review with Semen decided to add more benchmarks checks speed of OPC.
And, in case some problems will be found, need to refactor final solution
Possible refactoring ways:
1) Send ack not at each OPC.
2) Fix failover to make fullscan at failure instead of usage aditional map

> Looks like with {{onePhaseCommit}} return value for cache operation can be lost if primary node fails, {{GridNearTxPrepareResponse}} with return value is not received, but transaction executes 'check backup' step and finishes without error.
> Reproduces in {{IgniteCachePutRetryTransactionalSelfTest.testInvoke}}, also added one more test to check return value {{IgniteCachePutRetryTransactionalSelfTest.testGetAndPut}}.
> Please unmute tests on TC when fixed.
