on YouTube ↗38m

" summary

Vitess presents a MySQL sharding middleware that runs on Kubernetes, exposes a single endpoint via vtgate, and manages per-node MySQL with vttablet and a control plane; major adopters include Slack (25% migrated), Square and deployments with thousands of MySQL instances and five nines availability. Demo builds a cluster with the planet-scale operator, performs live resharding using VReplication (materialized views, row/column filters, aggregations), cuts over by blacklisting source, waiting for replication, then updating routing, with typical cutover seconds long and temporary double storage and write amplification.
