Is data compression all automatic? Or does manual steps occur in HANA Studio

Hi all,

I'm new to HANA and have been leveraging SCN in a BIG way to answer my questions (thanks everyone for your contributions). This is my first post as I was unable to find an answer to my current question .

I've been reading up on data compression in HANA and I learned that there are different techniques, such as Dictionary, Cluster, and Run-length encoding.
