Mike Percy commented on KUDU-484:
---------------------------------
I think we have the opposite problem where we are fsyncing too often during
remote bootstrap, but I need to look into this more closely w.r.t. directory
fsync.

> Key: KUDU-484
> URL: https://issues.apache.org/jira/browse/KUDU-484
> Project: Kudu
> Issue Type: Bug
> Components: tablet
> Affects Versions: M4.5
> Reporter: Mike Percy
>
> We need to ensure that all points at which we persist data are protected by
> (optional) fsync.
> At the time of this writing, we do not fsync on directory creation for
> blocks. We also do not fsync consistently when doing a remote bootstrap.
> Doing this in an optimal fashion requires an API that allows for control over
> fsync on blocks and block directories in batch fashion for remote bootstrap
> and in small batches or single files / directories for regular flushes.
