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
> Return value for cache operation can be lost with onePhaseCommit

> Key: IGNITE-1525
> URL: https://issues.apache.org/jira/browse/IGNITE-1525
> Project: Ignite
> Issue Type: Sub-task
> Components: cache
> Affects Versions: ignite-1.4
> Reporter: Semen Boikov
> Assignee: Anton Vinogradov
> Priority: Critical
> Fix For: 1.8
>
>
> 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.
