(was: 1.4.0)
> Snapshot Create requires Double Buffer Flush thread to split the commit batch
> -----------------------------------------------------------------------------
>
> Key: HDDS-7279
> URL: https://issues.apache.org/jira/browse/HDDS-7279
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: George Jahad
> Assignee: Hemant Kumar
> Priority: Major
> Labels: pull-request-available
> Fix For: HDDS-6517-Snapshot
>
>
> The OmRequest double buffer flush thread flushes the entire buffer as a
> batch. Since follower OM's will flush batches with different contents,
> snapshots can't stay consistent between the leader and the followers.
> This means the flush thread needs to be "snapshot aware" and split the batch
> so that all operations before the snapshot create are commited to rocksdb
> before the checkpoint is created.
> Details here:
