Re: HANA Merge and Optimize Compression process

Hello Lars,

Can you explain this? We are using BW 7.31 with HANA 97.02 and have an un-partitioned DSO table with 1.4 billion rows. Memory/Disk 110GB/120GB.

We deleted 400 Million rows and ran

MERGE DELTA OF TABLE-NAME WITH PARAMETERS ('FORCED_MERGE' = 'ON');

This ran successfully, and used about 300GB of memory to perform the merge.

Now it is 168GB im memory and 320GB on disk!

Thanks

PS I have your book.

Tom
