Magic Pocket has been around for a while [0]! I'm curious if there is anything especially new that prompted the QCon talk and this blog post or if it was just a good time?
Author here. We do try to post updates as much as we are able to in our blog: https://dropbox.tech/tag-results.magic-pocket. While the talk did go through details of the system we've covered in the past, the purpose of the talk was to convey my personal learnings of managing such a system at this scale. See key takeaways here: https://qconsf.com/presentation/oct2022/magic-pocket-dropbox.... Sustaining a high amount growth while maintaining high availability, durability, and efficiencies at this scale is very difficult to do.
