About PlanetScale
Managed MySQL on Vitess, with git-style branches and deploy requests.
PlanetScale is a cloud database platform built on Vitess, the same MySQL sharding layer that Slack, GitHub and HubSpot run their primary databases on. The platform gives a SaaS team a fully managed MySQL with horizontal sharding, branching that copies the schema (not the data) into an isolated branch, and deploy requests that gate every schema change behind a review and a queued, non-blocking migration.
For a typical Data Panda customer, the interesting tables sit on the production branch behind a Vitess router that may already shard a few of the larger ones by tenant or customer id. Pulling that database into a warehouse means reporting reads against a copy that joins to Stripe, HubSpot and the accounting ledger without putting load on the shards your application traffic is hitting. It also gives you a place to look at what changed across deploy requests, instead of finding out on Monday morning that the dashboard column quietly disappeared on Friday.
