Data partitioning in SAP hana is done in the 3 ways when it comes to single level partitioning: Hash, Round-robin and Range.
If I am using Hana as a data mart, have some queries on this concept.
1.Hash and Range require primary key to be part of partitioning columns and Round-robin do not. Can anyone tell exactly when to go for Hash, when to for round-robin and when to go for range.
2. In has partitioning, H(x) where x is the integer in the primary key field, is used to determine the partition in which the integer goes. Can anyone please provide more information on this. How hash function is used exactly for partitioning and how can we query to know the partitions?
