That 400TB in the image is a large database! I'm guessing that's not the largest in the PlanetScale fleet either. Very impressive and a reminder that you're strongly differentiated against some of the recent database upstarts in terms of battle tested mission critical scale. Out of curiosity how many of these large clusters are using your true managed 'as a service' offering or are they mostly in the bring your own cloud mode? Do you offer zero downtime migrations from bring your own cloud to true as a service?

That particular cluster has grown significantly since the post was written, and yes there are now quite a few others that are challenging it for the "largest" claim. :-)

These larger ones are fully using the PlanetScale SaaS, but they are using Managed -- meaning that there are resources dedicated to and owned by them. You can read more about that here: https://planetscale.com/docs/vitess/managed

All of the PlanetScale features, including imports and online schema migrations or deployment requests (https://planetscale.com/docs/vitess/schema-changes/deploy-re...) are fully supported with PlaneScale Managed.
