title: What library to use to achieve this aync operation in flask?
body: <p>I'm using flask to build the backend api for an application, one thing I need to do is:  </p>
  
  <pre><code>1. get the content the user submited 
  2. send a twitter with that content
  3. save the content to my DB and return the id of the new item
  </code></pre>
  
  <p>now the problem is that step 2 takes too long time so it slows down the total request time.</p>
  
  <p>to be more specific, step 2 is:  <code>twitter.send(content)</code></p>
  
  <p>How could I make step 2 async? PS: I don't need to know if step 2 is successful or not</p>
