Very interesting read. I've worked on game services, and there are a lot of scaling challenges compared to "traditional" apps. Majority of traffic write heavy (many common patterns for scaling read traffic don't help you), massive spikes of launch day players, followed by big drop offs and occasional spikes with content updates. The height of these spikes can also be unpredictable, you're never sure how many players you'll get. The team I worked in had success with DynamoDB which did a lot of the operational heavy-lifting to scale up and down as well handling scale. I would have liked a bit more specifics on their manual sharing solution, and how the vitess implementation differs.
