Abstract
A computer system detects a request, from a requestor, to access a first data object stored in a tiered data structure that includes internal nodes and leaf nodes. 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 locks the leaf node that includes the first data object. While the leaf node that includes the first data object is locked, the computer system transmits, to the requestor, a first conditional-update communication and detecting a first conditional-update response in response to the first conditional-update communication. In response to detecting the first conditional-update response corresponding to the first data object, the computer system performs one or more operations based on the first conditional-update response corresponding to the first data object before unlocking the leaf node that includes the first data object.
