> 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)
