Packages

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

Erlang implementation of RAFT Consensus Protocol

FerricFlow durable workflows and queues with native-protocol storage, Raft durability, and Bitcask persistence.

Official Elixir SDK for FerricStore over native TCP and stateless HTTP.

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

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

Ecto integration for FerricStore — query cache and cached repo.

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

Plug.Session.Store adapter backed by FerricStore.

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

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.
