Vitess: Unlimited Database Scalability

on YouTube ↗05m

" summary

Vitess is a sharded distributed layer on MySQL that claims to serve many millions of queries per second for users like Slack, GitHub and Cash App. It avoids auto sharding by requiring a configurable sharding key and supports composite keys, hotspot splitting and online zero-downtime online resharding so capacity grows by adding shards or commodity nodes. Runs on Kubernetes/Borg-like environments and shows data and charts backing those scalability claims.
