Vitess: Stateless Storage in the Cloud
Talkat KubeCon + CloudNativeCon North America 2019 · on Tuesday, 2019-11-19· at 15:20· Room 11AB - San Diego Convention Center, Upper Level·
summary
Vitess runs MySQL-based storage as a stateless storage system by pushing state into many small shards (recommended ~200–300 GB) and relying on semi-sync replication with tens or hundreds of replicas so a rescheduled pod can be rebuilt quickly; it adds a stateless proxy (VTGate proxy) and topology/backup abstractions (S3/GCS/mounted) to do fast failovers and catch-up restores, supports cross-shard copies with VReplication, and powers large deployments (customers report millions QPS and production on Kubernetes since 2016).
