Abstract

An index handler determines, with respect to a key to be inserted into an index, that a candidate destination node of the index meets a split criterion. The index handler generates and embeds a deferred split descriptor comprising an identifier of a new node within the destination node. Before an insert-completed indication is provided, the destination node is written to a back-end data store without acquiring a lock and without writing out the new node to the back-end data store. During the traversal of the index, the index handler identifies another deferred split descriptor indicating a second new node. After providing the indication that the key was successfully inserted, the index handler writes the second new node to the back-end data store.
