On: Incremental Builds in Gatsby Cloud

[kylemathews]

We recently introduced build optimizations for incremental data changes for self-hosted environments: https://www.gatsbyjs.org/docs/page-build-optimizations-for-i... and are continuing to improve build speed across platforms.

To reliably provide near real-time deployments, we need tight integration with the CI/CD environment to optimize and parallelize the work; that's why you’ll see the fastest builds and deploys through Gatsby Cloud — the platform is purpose built for Gatsby!
