eternal
A bulletproof Elixir library that keeps ETS tables alive forever using bouncing GenServers and scheduled monitoring.
What is eternal?
Eternal is an Elixir library that ensures ETS (Erlang Term Storage) tables remain alive indefinitely, even when owning processes crash. It solves the problem of losing in-memory data by using bouncing GenServers and scheduled monitoring to maintain both an owner and heir for each table. This provides a bulletproof solution for persistent storage in Elixir applications.
Elixir developers building applications that rely on persistent in-memory data storage via ETS tables, particularly those needing high fault tolerance and crash resistance.
Developers choose Eternal over alternatives like Immortal because it offers a more robust solution that doesn't require a single dedicated process, reducing crash risks through bouncing GenServers and scheduled monitoring. Its simple API and seamless integration with Elixir supervision trees make it easy to adopt while ensuring tables survive application restarts.
