How are savepoints triggered in an SAP HANA environment?

In an SAP HANA environment, savepoints are critical for ensuring data durability and consistency. They represent a specific point in time where the state of the database is saved to disk, allowing for recovery in case of a failure.

A savepoint is triggered by a database soft shutdown, which is a process that safely terminates all open transactions and writes the current state of the database to disk. This ensures that any changes made before the shutdown are not lost and can be recovered upon restarting the database. The mechanism of creating a savepoint in this manner helps maintain data integrity and consistency across the database.

In contrast, while some actions like running a query execution, performing a database backup, or manual invocation of commands might seem relevant to overall database operations, they do not directly trigger a savepoint. A query execution typically reads data without affecting the overall state unless it updates data, and while a database backup may involve savepoints, it is not the direct action that initiates one. Manual commands may lead to various operations but do not specifically relate to triggering savepoints in accordance with the soft shutdown process.
