Blog: How we captured billions of events in Django (and why we rewrote in Rust)

[ivanagas]

Changes

A big blog on the evolution of our capture endpoint, lightweight capture, and the process of rewriting in Rust. The goal is to show off the work we’ve done to help with recruitment (at the request from Tim)

I would appreciate feedback on:

• Am I missing any high impact activities done before lightweight capture to improve the capture endpoint?
• Specific technical details about why a decision was made, interesting aspects of the implementation, and the outcome of the decision, especially around the Rust rewrite.
• More details about why we chose Rust specifically.1

Reviewing or even pointing me to specific reviews and issues that would be helpful (I already used as many as I could find).

Anything we can do to nudge this one along? (e.g. can someone else review who isn't @timgl ?)

Happy to do an edit but would need someone to jump in and do the technical review ahead of that.
