Which of the following SAP recommendations should be followed for optimal table partitioning in SAP Business Suite powered by SAP HANA?

For optimal table partitioning in SAP Business Suite powered by SAP HANA, having a low number of keys is indeed the recommended approach. This strategy is based on the principle that fewer partition keys can lead to better performance by simplifying the data access paths and reducing the overhead associated with managing multiple partitions.

When tables are partitioned with a lower number of keys, it allows for a more efficient distribution of data within those partitions, leading to faster query execution times. The HANA database can leverage its in-memory capabilities better when dealing with simpler partitioning strategies, as the system can more effectively optimize data retrieval and processing operations.

A high number of keys or complex partitioning strategies can introduce additional complexity, potentially leading to slower performance as the HANA system may have to work harder to manage, access, and process the data spread across multiple partitions. Similarly, partitioning tables across multiple hosts might not provide benefits in all scenarios, particularly if the overhead of managing distributed data outweighs the performance gains.

Thus, adopting a strategy with a low number of keys aligns with HANA's design philosophy of maximizing performance through simplicity and efficiency.
