Optimizing rate limiting with flat files

The best code I've ever written was code I deleted. Negative lines of code is an underappreciated metric.

The elegant solution isn't the obvious one. Here's the pattern I've been using: keep the write path and read path completely separate. Writes go through a single, well-validated pipeline. Reads can be cached, denormalized, and optimized independently. This separation sounds like extra work, but it eliminates an entire class of bugs.

Ship first, optimize later. But document the tradeoffs now so future-you isn't puzzled.
