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.
