Aspects of the disclosure relate to hierarchical data structures. A method is disclosed for storing data in a hierarchical data structure. The method may include receiving first data to be committed in a distributed database, the first data including one or more data elements. A result of the selection function may be computed, applying the selection function to each of the one or more data elements. A first node of a first hierarchical data structure may be identified based on the result of the selection function applied to a first data element. The first node of the first hierarchical data structure may be updated using the first data element.
