"R" Integration in Hana

JK

Hi

is it possible to process 'r' calculations in-memory in hana?

if i look at the diagram of the sap hana r integration, it seems that all data is passed from hana to the rserve / r runtime and results back to hana

so i thinks this is slower than the PAL functions.

I don't think so. Currently it's impossible.

My colleague has made a comparison between R and PAL using k-means and the result is PAL is about 5 times faster than R. But R has more libraries than PAL...

Here is a blog post about the comparison, but in Chinese, sorry. http://scn.sap.com/community/chinese/hana/blog/2014/09/03/sap-hana%E6%95%B4%E5%90%88r%E7%9A%84%E6%80...

Best regards,
