Subject [jira] [Commented] (JENA-241) Add support for SAP database
Date Thu, 03 May 2012 07:44:05 GMT


Paolo Castagna commented on JENA-241:

Hi Fergal, interesting...

I have a few questions for you (just curious):

 - Is HAVA available somewhere?
 - What happens when your data do not fit into memory?
 - Have you run any benchmark (such as BSBM [1] or SP2Bench [2]) to compare performances with
one of the other SDB stores or TDB?

> I would like to contribute my complete and tested patch to make SDB compatible with SAP's
new in-memory, column-store (-possible) database codenamed HANA. I followed the instructions
here [1] to the letter, created the patch and tested by applying it cleanly. Now I can run
SPARQL endpoints on top of SAP's DB, and I'd like everyone else to be able to do this too.
I just need to check with SAP legal before I attach the patch to this issue as described at
[1]. Keep up the good work guys!
