A method includes partitioning a database table into a first plurality of partitions. A plurality of changes are executed on the database table in response to a transaction. The changes occur at a corresponding plurality of timestamps and result in a second plurality of partitions. The database table is updated to include a log with the plurality of changes. For each change of the plurality of changes, the log includes and an identification of a portion of the database table the change is applied to. A selection of a first timestamp and a second timestamp of the plurality of timestamps is detected. A delta is generated in response to the selection. The delta indicates a total change occurring to the database table between a first change of the plurality of changes corresponding to the first timestamp and a second change of the plurality of changes corresponding to the second timestamp.
