title: Get webflux event-loop scheduler
body: <p>I use <strong>webflux</strong> with <strong>netty</strong> and <strong>jdbc</strong>, so I wrap blocking jdbc operation the next way:</p>
  
  <pre><code>static &lt;T&gt; Mono&lt;T&gt; fromOne(Callable&lt;T&gt; blockingOperation) {
      return Mono.fromCallable(blockingOperation)
          .subscribeOn(jdbcScheduler)
          .publishOn(Schedulers.parallel());
  }
  </code></pre>
  
  <p>Blocking operation will be processed by the <strong>jdbcScheduler</strong>, and I want the other pipeline will be proccesed by <strong>webflux event-loop scheduler</strong>. </p>
  
  <p>How to get webflux event-loop scheduler?</p>
