Horizontal Scaling with Vitess

on YouTube ↗36m

" summary

Vitess is a MySQL-compatible sharding and proxy layer used by PlanetScale that demos transparent resharding on Kubernetes: a live cluster moves from ~800 to 1,500 QPS, then splits one shard into two via a resharding workflow using vtctl, with vttablet sidecars and vtgate routing. Latency falls from ~7–8 ms at 1,500 QPS to ~5–5.5 ms after sharding, failover completes in ~15–20 seconds, recommended shard size ~256 GB, and users include Slack, Square and jd.com (10,000+ DBs).
