Coming from the Python world, parallel or asynchronous code was a completely foreign concept. Sure, there are the <a href="https://docs.python.org/3/library/asyncio.html">asyncio</a> and <a href="https://docs.python.org/3/library/multiprocessing.html">multiprocessing</a> packages in the standard library, but I&rsquo;ve never had a good reason to actually use them. Working in the data space with Python typically meant that I never needed to worry about any of these concepts. They are just magically handled by a library (e.g. Pandas, Spark, etc.). So what is asynchronous code? What is parallel code? Are they actually meaningfully different?</p>
