>                 URL: https://issues.apache.org/jira/browse/IGNITE-7934
>             Project: Ignite
>          Issue Type: Improvement
>    Affects Versions: 2.4
>            Reporter: Ilya Lantukh
>            Priority: Major
>
> 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.
