SPS03 introduces a couple of interesting new capabilities to R Integration for SAP HANA…

Firstly, it’s now possible to create your remote sources interactively via the Database Explorer (in addition to using SQLScript of course!):

Watch this video tutorial to see the this in action: Getting Started with SPS03

Secondly, the SQLScript Plan Profiler has been introduced and makes detailed performance statistics available for stored procedures and functions. This can help you identify performance bottlenecks in your applications.

What’s really nice is that R integration (RLANG) is fully supported – so you can use this capability with your R procedures:

You can use a hint on the procedure call to see results immediately:

CALL "R_CLUSTER" ("DATA", "PARAMS", "RESULTS") WITH OVERVIEW WITH HINT(SQLSCRIPT_PLAN_PROFILER);

Results look something like this:

Or you can turn profiling on/off for a given procedure and results are stored and available via a system view:

ALTER SYSTEM START SQLSCRIPT PLAN PROFILER FOR PROCEDURE "RUSER"."R_CLUSTER";

SELECT * FROM "M_SQLSCRIPT_PLAN_PROFILERS";

-- call the procedure directly in your application

SELECT * FROM "M_SQLSCRIPT_PLAN_PROFILER_RESULTS";

ALTER SYSTEM STOP SQLSCRIPT PLAN PROFILER FOR PROCEDURE "RUSER"."R_CLUSTER";

ALTER SYSTEM CLEAR SQLSCRIPT PLAN PROFILER FOR PROCEDURE "RUSER"."R_CLUSTER";
