Hyperactive: HTTP/2 and Python

Hyperactive: HTTP/2 and Python

The internet has spoken, HTTP is to get its first serious update in 15 years. In this talk we'll discuss what HTTP/2 is, why it's happening, and how it's going to affect you and everyone you love. We'll briefly talk about how you can get started with HTTP/2, and some interesting projects associated with it, including Hyper, the first Python HTTP/2 library.

  7. HTTP/1.1 is Old

  8. HTTP/1.1 is Inefficient

  9. HTTP/1.1 is Slowing Us Down

  10. HTTP/2

  11. Binary • Text protocols are easy to debug but complex

    to parse • Binary is simpler. • Simpler (usually) means faster
  12. Efficient • Multiplexing (with priority/flow control) • Header compression (HPACK)

    • Early stream termination. • Server Push
  13. Not universally well received

  14. Poul-Henning Kamp • “HTTP/2.0 is not a technical masterpiece…I would

    flunk students in my (hypothetical) protocol design class if they submitted it.”
  15. None
  16. Imperfect

  17. HTTP/2 is Imperfect • Difficult to reason about • Challenging

    to debug • Awkward edge cases • Inherently concurrent
  18. Bloody Good!
