Abstract
A computer system detects a request to access a first data object stored in a tiered data structure, that includes internal nodes and leaf nodes, where data objects in the leaf nodes include unique key information and corresponding values, and the first data object is uniquely identified by a first key. In response to detecting the request to access the first data object, the computer system retrieves a leaf node that includes the first data object and identifies the first data object in the leaf node by combining unique key information of the first data object with a key prefix that is stored separately in the leaf node to generate a combined key and determining that the combined key matches the first key that uniquely identifies the first data object. After identifying the first data object, the computer system provides access to the first data object.
