Abstract: Computing resource service providers operate various services used to provide functionality to customers and other computing resources operated by various entities. These services may use consistent hash rings to direct a request to a particular worker. Previous versions of the consistent hash ring may be maintained such that predecessor information can be determined. When a request is received the request and predecessor information may be provided to a worker manager. The worker manager may utilize the predecessor information to obtain state information from a predecessor worker manager. The state information may then be used to process the request.
