Disk storage in HANA


Hi All,

How does Delta Merge affect the disk space occupied by a table. I have observed that upon Delta Merge the disk space occupied by a table comes down but am not quite sure about the reasons for the same.

Besides, does HANA perform any compression/ encoding while storing data on the disk as well or are these only for the in-memory section.

Pl advise. Thanks.
