Hi All,
We are working on HANA Studio Rev 68.
Have few Stored Procedures with medium complex logic to fetch data from underlying tables with approx 50 - 100 million rows.
What we noticed is that - if i trigger one Stored procedure; i see about 15 to 17 threads scheduled in background to complete the job.
Here, the stored procedure might be as simple as reading from a source table and updating few fields in target table (1:1 mapping).
Catch is the volume of source table is say about 200 million.
The source or target table is not partitioned.
If i try to co-relate with the BW world then we have a setting on DSO's to limit the number of parallel threads utilized.
Similarly is there any setting that can define maximum number of threads to be used for a job processing in HANA?
Also - got to know that certain sql statements like "if then" causes a performance issue. If someone could help clarify that as well, it would be great.
Regards
