Patent attributes
Systems, methods, and devices for scheduling of data processing tasks are disclosed. A method includes performing a modification on a first set of immutable partitions storing database data to generate a second set of immutable partitions. The second set is associated with a modified version of the database data. A change tracking entry is entered in a stream of tracking entries based on committing the modification. The change tracking entry includes an indication of the modification on the first set of immutable partitions. A stream offset of the stream of tracking entries is advanced based on the entering of the change tracking entry in the stream of tracking entries. The stream offset indicates a timestamp associated with a latest committed modification to the database data. A data processing task is scheduled for execution on the modified version of the database data based on the advancing of the stream offset.
