What performance techniques should you implement to improve the performance of SAP HANA information views?

Implementing the technique of pushing down aggregations to SAP HANA significantly enhances performance because it allows the database to handle computing at the storage level where the data resides. By executing aggregations directly within the HANA database rather than transferring raw data to another system for processing, the amount of data that needs to be transferred and processed externally is dramatically reduced. This is especially beneficial in a high-performance environment like HANA, where its in-memory capabilities can quickly execute these operations.

This approach leverages HANA's architecture, designed for real-time data processing, and ultimately reduces latency and increases responsiveness in query performance. By utilizing this technique, organizations can achieve faster data retrieval times and optimize resource utilization, making it a vital practice for maintaining efficient information views.

The other techniques presented can support performance improvements but don’t primarily focus on leveraging HANA’s strengths in the same way pushing down aggregations does. For instance, minimizing data transfer and investigating partitioning can help optimize performance as well, but pushing down processing tasks to the database engine itself is often the most effective strategy. This method harnesses the capabilities of HANA more effectively by allowing it to do what it does best—performing calculations rapidly on in-memory data.
