[jira] [Created] (IGNITE-9949) MVCC TX: Scan query can return wrong
result on unstable topology
Roman Kondakov created IGNITE-9949:
--------------------------------------
Summary: MVCC TX: Scan query can return wrong result on unstable topology
Key: IGNITE-9949
URL: https://issues.apache.org/jira/browse/IGNITE-9949
Project: Ignite
Issue Type: Bug
Components: mvcc
Reporter: Roman Kondakov
Fix For: 2.8
Scan query map nodes do not take into account topology version when filtering primary partitions. See method {{GridCacheQueryManager#scanIterator}} - each node takes it's current topology version. This causes wrong partition filtering results.
To fix this problem the single topology version should be taken on reduce node propagated to map nodes.
