摘要: Techniques and solutions are provided for performing transactions within a database system that stores database data using a row store and a column store. For example, a transaction that performs operations to update data in both the row store and the column store can use the same transaction object. The state of the transaction can be atomically changed. For example, the state of the transaction object can be atomically changed from uncommitted to committed (e.g., set to a commit identifier to represent the committed state).

摘要: Technologies are described for restarting an application while maintaining data in memory (e.g., using shared memory). For example, shared memory can be associated with an application. The shared memory can also be associated with a holder process to maintain the shared memory from the time the application stops to the time the application starts again. When the application starts, the shared memory can be associated with the started application. In addition, restart of in-memory databases can be provided using shared memory. For example, in-memory data can be maintained when a database process or database management system stops and starts (e.g., during a restart).
