The first decision was that we were going to treat first-class file access on S3 as a presentation layer for working with data. We would allow customers to define an S3 mount on a bucket or prefix, and that under the covers, that mount would attach an EFS namespace to mirror the metadata from S3. We would make the transit and consistency of data across the two layers an absolutely central part of our design. We started to describe this as “stage and commit,” a term that we borrowed from version control systems like git—changes would be able to accumulate in EFS, and then be pushed down collectively to S3—and that the specifics of how and when data transited the boundary would be published as part of the system, clear to customers, and something that we could actually continue to evolve and improve as a programmatic primitive over time. (I’m going to talk about this point a little more at the end, because there’s much more the team is excited to do on this surface).
