Abstract
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).
