title: Consume REST API from Python: do I need an async library?
body: <p>I have a REST API and now I want to create a web site that will use this API as only and primary datasource. The system is distributed: REST API is on one group of machines and the site will be on the other(s).</p>
  
  <p>I'm expecting to have quite a lot of load, so I'd like to make requests as efficient, as possible.</p>
  
  <p>Do I need some async HTTP requests library or any HTTP client library will work?</p>
  
  <p>API is done using Flask, web site will be also built using Flask and Jinja as template engine.</p>
