--------------------------------
Summary: 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
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.
