> Host replacement is possible to produce orphaned hints files that the original associated host ID no longer exist in the cluster (i.e., being replaced). Those orphaned hints files will not be dispatched and only consumes up the disk space. 
> We can have a background schedule that infrequently checks and deletes the files if they are orphaned and have exceeded the TTL.
