Abstract

A writer writes items to leaf nodes of a tree, and a reader read items from the leaf nodes. Each node comprises a respective first block and second block, the first block comprising a plurality of the items of the respective leaf sorted in order of key. When writing new items to a leaf, the writer writes the new items to the second block of the identified leaf node in an order in which written, rather than sorted in order of key. When reading one or more target items from a leaf, the reader searches the leaf for the one or more target items based on a) the order of the items as already sorted in the first block and b) the reader sorting the items of the second block by key relative to the items of the first block.
