Method Detail

public OptionalLong getPauseNsFromException(Throwable error,
                                            int tries,
                                            long startNs)

Returns the nanos, if any, for which the client should wait

Parameters:

error - The exception from the server

tries - The current retry count

Returns:

The time, in nanos, to pause. If empty then pausing would exceed our timeout, so we should throw now
