Interface ConnectionBackoffStrategy

  • All Known Implementing Classes:

    public interface ConnectionBackoffStrategy
    When managing a dynamic number of connections for a given route, this strategy assesses whether a given request execution outcome should result in a backoff signal or not, based on either examining the Throwable that resulted or by examining the resulting response (e.g. for its status code).
