CockroachDB
summary
A distributed, transactional SQL database implemented built in Go exposes a single sorted keyspace split into ~64MB ranges that are replicated 3x (or 5x) and run an independent raft per range for consensus; storage uses RocksDB and protobufs, MVCC plus optimistic concurrency control provides serializable (default) or snapshot isolation, and sync.Pool and embedded arrays reduce GC pressure. A three-node demo survives one node failure and halts without quorum; rebalancing is still unfinished and beta targets end of year.
