Abstract
A system for write optimization in transactional data management systems is described. The system stores a tree data structure that comprises a root, a plurality of internal nodes, and a plurality of leaf nodes. Each internal node comprises a pivot key and a child pointer. Each leaf node stores key-value pairs sorted by a corresponding key. The system forms a plurality of hybrid nodes. The hybrid nodes comprise a layer of internal nodes that are immediate parents of the plurality of leaf nodes. A buffer is formed only for each internal node of the plurality of hybrid nodes. The buffer is used to store a message that encodes an operation. The message is to be applied to the corresponding leaf nodes of the plurality of hybrid nodes.
