EKV is a distributed key-value store for Elixir that uses SQLite as its storage backend and provides eventual consistency with optional per-key linearizable compare-and-swap operations. It replicates data across Erlang nodes using delta sync, survives node failures and network partitions, and offers zero runtime dependencies through vendored SQLite compiled as a NIF.
A Polyglot Conference built a website serving data through APIs written in 27 different programming languages, with each request displaying which language handled it. The site uses Elixir and Phoenix for the frontend, PostgreSQL for storage, and implements caching, timeouts, and prewarming to optimize performance across the diverse backend APIs.
