Speed Up Your Data Processing: Parallel and Asynchronous Programming in Data Science


Are you constantly waiting for your data processing code to finish executing? Through real-life stories, we will explore how to leverage parallel and asynchronous programming in Python to speed up your data processing pipelines - so that you can focus on getting value out of your data.


In any data-intensive application, one of the biggest bottlenecks (in terms of time) is the constant wait for the data processing code to finish executing. Slow code, as well as connectivity issues, affect every step of a typical data science workflow — be it for event-driven I/O operations or computation-driven workloads.

In this talk, I will be exploring what we can do to speed up our code while sharing my own real-life experience of working in a young data science team. I will talk about:

  1. Sequential vs parallel processing,
  2. Synchronous vs asynchronous execution,
  3. Event-driven I/O operations vs computation-driven workloads in a data science workflow,
  4. When is parallelism and asynchronous programming a good idea,
  5. How to implement asynchronous programming to speed up your data processing pipelines
