> Avoid fsync-per-block in tablet copy
> ------------------------------------
>
> Key: KUDU-1726
> URL: https://issues.apache.org/jira/browse/KUDU-1726
> Project: Kudu
> Issue Type: Bug
> Components: tablet
> Reporter: Mike Percy
> Assignee: Hao Hao
> Fix For: 1.5.0
>
>
> We should be able to do a full tablet copy, keeping in mind which blocks and
> WAL segments have changed, and then do a bulk sync-to-disk once the full
> operation is complete. This would allow the kernel to schedule the IO at its
> leisure until durability is actually required.
> This will likely require changes from the BlockManger API and LogBlockManager
> implementation to support.
