HANA tables size on disk is reducing

Hi Lars,

Came across your statement "The primary storage is memory for SAP HANA, so whatever ends up on disk is equivalent to a database backup." here and i got one question:

Any clue what cause db bakup size (sum(allocatd_page_size) is much greater than disk size (sum(disk_size) for M_TABLE_PERSISTENC_STATISTICS)? The size diff is around 50GB~~~ Delta merge is running correctly.

this is quite abnormal with such a large gap. Checked on others systems, where the gap is around 5-10GB.

Hope to hear from you soon,

Thanks in advance,

Nicholas Chang
