Dear HANA grus,
I've just finished table partitioning jobs for CDPOS(change document item) with 4 partitions by hash with 3 columns.
Total data volumn is around 340GB and the table size was 32GB !!!!!
(migration job was done without disabling CD, so currently deleting data on the table with RSCDOK99)
Before partitioning, the data volumn of the table was around 32GB.
After partitioning, the size has changed to 25GB.
It took around One and half hour with exclusive lock as mentioned in the HANA adminitration guide.
(It is QA DB, so less complaints)
I thought that I might not can do this in the production DB.
Does anyone hava any idea for accelerating this task?? (This is the fastest DBMS HANA!!!!)
Or Do you have any plan for online table partitioning functionality??(To HANA Development team)
Any comments would be appreciate.
Cheers,
- Jason
