Abstract
Various systems and methods of tracking database partition change log dependencies are described herein. A system is disclosed herein, according to some embodiments. A change log for a database partition of the plurality of database partitions is stored to a log store. An indication that a split of the database partition into two or more child database partitions has occurred is received. Responsive to the split of the database partition, the change log is split into two or more corresponding child change logs. A portion of the change log is deleted responsive to a determination that a respective complete snapshot is stored for each child database partition corresponding to a child change log of the change log and a determination that a retention window for the portion of the change log has passed.
