             Summary: Do not checkpoint pages from MOVING partitions
                 Key: IGNITE-7934
                 URL: https://issues.apache.org/jira/browse/IGNITE-7934
             Project: Ignite
          Issue Type: Improvement
    Affects Versions: 2.4
            Reporter: Ilya Lantukh
            Assignee: Ilya Lantukh


To remove necessity to acquire checkpoint lock and write records to WAL while processing supply messages, it might be beneficial to skip pages from MOVING partitions during checkpointing. 

The only problem that it might cause is index consistency, which can be avoided by splitting rebalancing in 2 steps:
1. data preloading;
2. index rebuild.
