Gated Deployments: addressing the complexity of schema deployments at scale

Today we introduce Gated Schema Deployments, which help us think of schema changes as more of atomic operations, solve the complexity of making changes across a sharded database, and answer one of the most common requests from our users. Let’s first understand what the deployment complexity is. PlanetScale already offers non-blocking schema changes. You make some schema changes in your development branch, you submit a deployment request, it gets approved, and each change is then applied, non-int
