Packages

ArchUnit-inspired architecture testing library for Elixir. Write ExUnit tests that enforce dependency rules, layered architecture, modulith bounded contexts, and naming conventions.

Probabilistic data structures for Elixir — Bloom filter, Count-Min Sketch, HyperLogLog, t-digest, and more.

Distributed persistent key-value cache with Redis wire protocol (RESP3), Raft consensus, and Bitcask storage engine.

Resilience and concurrency toolkit for Elixir — bulkhead, circuit breaker, retry, hedged requests, single-flight, task combinators, and weighted semaphore.

Raft library — FerricStore fork with pluggable WAL I/O

Deduplicate concurrent function calls by key. Inspired by Go's singleflight.

Hedged requests for Elixir — fire a backup request after a delay, take whichever finishes first, with adaptive delay tuning.

Ecto integration for FerricStore — query cache and cached repo.

Plug.Session.Store adapter backed by FerricStore.

Functional retry with backoff for Elixir — composable strategies, zero macros, injectable sleep.

Higher-level Task combinators for Elixir — race, all_settled, map with bounded concurrency, and sequential fallback chains.

A weighted semaphore for bounding concurrent access to a shared resource.
