ExHammer/hammer

This system is a high-performance rate-limiting library for Elixir that provides multiple throttling algorithms, including fixed window, sliding window, leaky bucket, and token bucket. It supports two distinct backends—Erlang's :atomics for lock-free concurrency and ETS for in-memory storage—allowing users to choose the implementation that best fits their performance and consistency requirements. The library manages request counts and expiration, ensuring that applications can effectively control traffic and prevent abuse through configurable limits.

The project established its foundational structure and tooling while significantly refactoring the Hammer library to support multiple rate-limiting algorithms via a new macro-based API. This period introduced an atomic backend alongside an updated ETS backend, accompanied by comprehensive test coverage for various key types.

The project expanded its rate-limiting capabilities by introducing ETS and atomic backends for five new algorithms: Fixed Window, Sliding Window, Leaky Bucket, and Token Bucket. Comprehensive test suites were added to verify correctness and concurrency safety, while benchmarks were introduced to compare the performance of these new implementations.
