Khepri - Mnesia replacement
summary
Khepri is a Raft‑based replacement for Mnesia implemented to be Erlang embeddable and uses Raft for consensus while optionally plugging in local KV engines like SplinterDB or RocksDB. A prototype already migrates virtual hosts, users and permissions and reports double‑digit throughput improvements over Mnesia using a minimal Raft state machine. It lacks multi‑key transactions, needs a majority of nodes, supports deletes and snapshots, is feature‑flagged for incremental rollout, is under 2,000 LOC with tests, and excludes storing messages.
