Dear All,

I would like to ask whether Lustre file system has implemented the
function to optimize for large sparse data files ?

For example, a 3GB data file but with more than 80% bytes zero, can
Lustre file system optimize the storage not actually taking the whole
3GB of disk space ?

I know that some file systems (e.g., ZFS) has this function. If Lustre
does not have it, is there a roadmap to implement it in the future ?

Thanks for your reply in advance.

Best Regards,
