Ivan Pavlukhin commented on IGNITE-12482:
-----------------------------------------
Merged to master. No release nodes as it fixed a bug introduced in 2.8. So, no
visible changes comparing to previous versions.
> SQL: sql returns incorrect results for replicated caches if started on node
> where rebalance is in progress
> ----------------------------------------------------------------------------------------------------------

> Key: IGNITE-12482
> URL: https://issues.apache.org/jira/browse/IGNITE-12482
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Reporter: Ivan Pavlukhin
> Assignee: Ivan Pavlukhin
> Priority: Blocker
> Fix For: 2.8
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> To reproduce you should do next:
> 1)Start 3 data nodes with persistence
> 2)Load 100_000 entries to SQL cache
> 3)Stop one node
> 4)Load another100_000 entries to SQL cache
> 5)Stop second node
> 6)Load another100_000 entries to SQL cache
> 7)Start node one and node2 -> rebalance will be started
> 8)In parallel start select count query from every data node
> Results will be like next.
> SqlSize is 300000, Ignite is
> sqltests.IncorrectSizeDuringRebalanceOfReplicatedCachesTest2
> SqlSize is 122684, Ignite is
> sqltests.IncorrectSizeDuringRebalanceOfReplicatedCachesTest1
> SqlSize is 26898, Ignite is
> sqltests.IncorrectSizeDuringRebalanceOfReplicatedCachesTest0
> Cache sizes will be correct in this case:
> CacheSize is 300000, Ignite is
> sqltests.IncorrectSizeDuringRebalanceOfReplicatedCachesTest2
> CacheSize is 300000, Ignite is
> sqltests.IncorrectSizeDuringRebalanceOfReplicatedCachesTest1
> CacheSize is 300000, Ignite is
> sqltests.IncorrectSizeDuringRebalanceOfReplicatedCachesTest0
> It means that during rebalance customers will be able to get incorrect
> results for SQL queries during the rebalance process if it will be started
> from "bad" node.
