> This will give File Channel performance a big boost, at the cost of possible
> data loss if a crash happens between checkpoints.
> Also we should make it configurable, with default to false. If the user does
> not mind slight inconsistencies, this feature can be explicitly enabled
> through configuration. So if it is not configured, then the behavior will be
> exactly as it is now.
