Building a Multi-Master Distributed Redis in Erlang
summary
A Redis-compatible server called Edis is built in Erlang and presented as a multi-master experiment that actually runs: it uses LevelDB backend by default, exposes the Redis protocol, and broadcasts updates across nodes with gen_server casts. Consensus and leadership use paxos for leader election and vector clocks detect stale keys; conflicts currently resolve with a latest-wins rule. Implementation is slower than native Redis, many Redis features are incomplete, and the project is explicitly experimental rather than production-ready.
