---------------------------------------
Summary: WalStateNodeLeaveExchangeTask prevents merge exchanges on
leaving many nodes
Key: IGNITE-8474
URL: https://issues.apache.org/jira/browse/IGNITE-8474
Project: Ignite
Issue Type: Bug
Affects Versions: 2.5
Reporter: Sergey Chugunov
Assignee: Sergey Chugunov
Fix For: 2.6
Exchange merge mechanism provides huge optimization when a lot of nodes join or
leave cluster simultaneously.
In IGNITE-7003 WalStateNodeLeaveExchangeTask custom exchange task was added
which is generated for each NODE_LEFT/NODE_FAILED event.
Because of property skipForExchangeMerge set to false on this task it prohibits
exchange merge optimization.
The property needs to be reconsidered and changed if it is not crucial for this
functionality.
