I'm the PMT for this project in the EFS team. The "flip the switch" part was indeed one of the harder parts to get right. Happy to share some limited details. The performance improvement builds on a distributed consistent cache. You can enable such a cache in multiple steps. First you deploy the software across the entire stack that supports the caching protocol but it's disabled by configuration. Then you turn it for the multiple components that are involved in the right order. Another thing that was hard to get right was to ensure that there are no performance regressions due to the consistency protocol.
Shameless plug, only one I promise. If you think this is cool, we are hiring for multiple PMT and SDE positions, which can be fully remote at the Sr. level and above. DM me for details, see [1], or see amazon.jobs and search for EFS.
