> Need to support the new checkpoint feature not wait for the previous

> Key: IGNITE-10508
> URL: https://issues.apache.org/jira/browse/IGNITE-10508
> Project: Ignite
> Issue Type: Improvement
> Reporter: Dmitriy Govorukhin
> Assignee: Dmitriy Govorukhin
> Priority: Major
> Fix For: 2.8
>
>
> There are cases we should trigger the checkpoint, some operations will be
> sure that all operation finished before the checkpoint. It is necessary to
> support the possibility of run checkpoint without waiting for the completion
> of the previous checkpoint.
> Solution:
> Merge checkpoint pages and append write new dirty pages to a current
> checkpoint.
> Restrictions:
> Trigger new checkpoint should not wait for the previous checkpoint operation
> completed.
> - It should not break crash recovery mechanisms
> - Only one merged is allow in the first implementation (potentially OOM, if
> we will try to merge many checkpoint operations)
