Andrew Mashenkov updated IGNITE-10187:
--------------------------------------
Ignite Flags: (was: Docs Required)
> Partition data can be lost after recover from WAL and no data were ever
> checkpointed.
> -------------------------------------------------------------------------------------
>
> Key: IGNITE-10187
> URL: https://issues.apache.org/jira/browse/IGNITE-10187
> Project: Ignite
> Issue Type: Bug
> Components: persistence
> Reporter: Andrew Mashenkov
> Priority: Major
>
> Steps to reproduce:
> 1. Start a node.
> 2. Disable checkpoints.
> 3. Put some data.
> 4. Flush WAL.
> 5. Restart node.
> 6. Next put hangs sporadically forever awaiting for next topology that will
> never happens.
> The issue caused by ClusterTopologyException thrown due to partition MOVING
> state, however it is expected partition to be in OWNING state.
> The root cause is partition doesn't restore OWNING state after recover from
> WAL as it was not checkpointed or contains no data when checkpoint occurs
> (partition was in initial state).
>
> Seems, forcing checkpoint before disabling it resolves the issue. See
> CacheMvccTxFailoverTest.testSingleNodeTxMissedCommitNoCheckpoint().
