Scaling Databases with Vitess

on YouTube ↗41m

" summary

Vitess provides horizontal sharding for MySQL and shows a live migration path: the demo uses the move_tables command plus a vtgate/vttablet sidecar and a vstream that keeps source RDS and target Vitess in sync (observed lag ~1s) while copying data, then atomically switches reads/writes with minimal errors during app restart. Claimed overhead is ~1–2 ms, backups land in S3 (PITR via binlog server Ripple), Planetscale runs tens of thousands of clusters and clients like JD reported 35M QPS on Vitess.
