Given a SELECT SINGLE statement from a large SAP HANA database table, which settings should you configure for the data source?

The most suitable choice for configuring the data source in a SELECT SINGLE statement from a large SAP HANA database table is to set the Load Unit to Page Loadable. This setting optimizes performance by allowing the system to handle data in a more efficient manner when accessing rows.

In SAP HANA, when utilizing SELECT statements, especially for scenarios where single row retrieval is needed, page loading can significantly reduce the response time since it minimizes the amount of data that needs to be accessed and moved in memory. Page Loadable means that data is arranged in memory that can be fetched in larger chunks rather than pulling data row by row. This is beneficial for performance, particularly in large datasets.

In contrast, while column stores are highly efficient for analytical queries due to their ability to compress data and allow for faster read access of specific columns, the focus here is on the retrieval of specific rows. Therefore, for the task at hand — running a SELECT SINGLE — the emphasis on page loadable is more aligned with the operational needs of retrieving specific data efficiently.

The choices related to storage type—whether to use Row Store or Column Store—do have implications on performance but are context-dependent based on the type of queries typically executed against the table. Hence, while they are
