Abstract: A computer-implemented method includes observing, by a computer device, a plurality of uniform resource locators (URLs); parsing, by the computer device, a URL path of each of the URLs into path segments; creating, by the computer device, a tree structure, the tree structure having a plurality of nodes, each node representing a particular path segment of the path segments; determining, by the computer device, a confidence factor for a first path in the tree structure using a decay function, the first path having an end node; and compacting, by the computer device, sibling nodes of the nodes into a compacted node in response to a number of the sibling nodes exceeding a variance threshold.

Abstract: A computer-implemented method includes: randomly generating, by a process running on a computer device, a reset time for the process; broadcasting a message to other processes in a cluster, the message including the reset time; entering a running state; receiving another message from one of the processes, the other message including another reset time; comparing the other reset time to the reset time; and in response to the comparing, the process performs one of: continuing in the running state based on the other reset time being different than the reset time; and randomly generating a new reset time for the process based on the other reset time coinciding with the reset time.
