      • getHedgeOnPerTryTimeout

        public boolean getHedgeOnPerTryTimeout()
         Indicates that a hedged request should be sent when the per-try timeout is hit.
 This means that a retry will be issued without resetting the original request, leaving multiple upstream requests in flight.
 The first request to complete successfully will be the one returned to the caller.
 * At any time, a successful response (i.e. not triggering any of the retry-on conditions) would be returned to the client.
 * Before per-try timeout, an error response (per retry-on conditions) would be retried immediately or returned ot the client
   if there are no more retries left.
 * After per-try timeout, an error response would be discarded, as a retry in the form of a hedged request is already in progress.
 Note: For this to have effect, you must have a :ref:`RetryPolicy <envoy_v3_api_msg_config.route.v3.RetryPolicy>` that retries at least
 one error code and specifies a maximum number of retries.
 Defaults to false.
        bool hedge_on_per_try_timeout = 3;
        Specified by:
        getHedgeOnPerTryTimeout in interface HedgePolicyOrBuilder
        Returns:
