Intro: Vitess
summary
Vitess is MySQL sharding middleware that provides cloud‑native scaling and five‑nines availability, implemented as VTGate/VTTablet proxies with VReplication. It supports replica routing, vertical and horizontal splits, two‑phase commit for cross‑shard writes, and reversible migrations; a laptop demo performs a vertical split demo and fast master switchover. Large adopters include 3,000 databases, 18,000 tablets at JD and partial Slack migration; expected per‑query overhead is about 4–5ms added latency while throughput and HA improve.
