          @Deprecated
          public DeploymentOptions setMultiThreaded(boolean multiThreaded)

      Deprecated. as of 3.6.0
      Set whether the verticle(s) should be deployed as a multi-threaded worker verticle.

      WARNING: Multi-threaded worker verticles are a deprecated feature.

      Most applications will have no need for them. Because of the concurrency in these verticles you have to be very careful to keep the verticle in a consistent state using standard Java techniques for multi-threaded programming.

      You can read the documentation that explains how you can replace this feature by the usage of custom worker pools or `executeBlocking` calls.

        `multiThreaded` - true for multi-threaded worker, false otherwise

        a reference to this, so the API can be used fluently

      This can be used to detect where the user is blocking a worker thread for too long. Although worker threads can be blocked longer than event loop threads, they shouldn't be blocked for long periods of time.

      Returns:
        The value of max worker execute time, the default value of `setMaxWorkerExecuteTimeUnit(java.util.concurrent.TimeUnit)` `maxWorkerExecuteTimeUnit` is `TimeUnit.NANOSECONDS`

          public TimeUnit getMaxWorkerExecuteTimeUnit()

      Returns:
        the time unit of `maxWorkerExecuteTime`
