elixir_locker

Locker is an Elixir wrapper for the locker Erlang library, which is a distributed, decentralized, consistent in-memory key-value store. It simplifies using locker for distributed locks, mutexes, and leader election in Elixir applications by providing convenient abstractions and OTP integration.

Key Features

• Global Process Registration — Automatically registers GenServer or :gen_fsm processes to the locker key-value store across a cluster using Locker.Server and Locker.Fsm modules.
• Distributed Resource Locking — Provides a direct API for creating and managing global locks with configurable lease times via the Locker module.
• Lease Management — Handles automatic lease renewal for registered processes and releases names on process termination to maintain consistency.
• Cluster Awareness — Enables querying and accessing registered processes or locks from any node in an Erlang cluster.

Philosophy

Locker aims to make distributed coordination in Elixir straightforward by wrapping the robust locker Erlang library with idiomatic Elixir abstractions and seamless OTP integration.
