Abstract
A data storage system may implement implicit checkpoint for generating a secondary of a table. Indexing updates may be replicated and maintained across a replica group storing a table for a data store. Upon detection of a restart event for generating a secondary index, a replica in the replica group may evaluate the indexing updates to determine an index creation restart point according to an order for indexing the table. The generation of the secondary index may be resumed at the index creation restart point. In this way, secondary index generation may continue whether or not a previously indexing replica in the replica group, such as a master replica, is available to continue generating the secondary index.
