PlanetScale introduced Neki, a system that adds a router, sidecars, and control plane on top of standard Postgres to enable horizontal scaling across many real Postgres shards. It supports online resharding, shard splitting, high-availability clusters per shard, topology-aware connection pooling, and coordinated schema changes without downtime.
