Classification: CPC G | IPC G

Claim 18:
19. A computer-storage medium comprising instructions that, when executed by one or more processors of a machine, configure the machine to perform operations comprising:
partitioning at a first computing node, a database table into a first plurality of partitions;
executing a plurality of changes on the database table in response to a transaction, the plurality of changes occurring at a corresponding plurality of timestamps and resulting in a second plurality of partitions of the database table;
updating the database table to include a log with the plurality of changes, for each change of the plurality of changes, the log including and an identification of a portion of the database table modified based on execution of the change;
detecting a selection of a first timestamp and a second timestamp of the corresponding plurality of timestamps, the selection received at t he first computing node;
generating a delta based on the log and in response to the selection, the delta being separate from the second plurality of partitions and indicating 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; and
providing the delta to at least a second computing node.
