How does SAP HANA create a save point?

SAP HANA creates a save point every few minutes to ensure data consistency and durability in the system. This process occurs as part of its data management strategy, which enables the system to maintain a consistent state and allows for the recovery of data in case of a failure. The save point mechanism captures the current state of the in-memory data and writes it to persistent storage. This helps prevent data loss by enabling the system to roll back to the last save point in the event of a crash or unexpected shutdown.

This frequent save point generation minimizes the risk of losing large amounts of data while balancing performance and system resource utilization, making it a critical part of maintaining the health and stability of the HANA database environment.
