Great talks Marc! Really interested in the approach you all took with DSQL. Am curious how the adjudicators will be tuned to minimise write skew across so many different workflows! Will lookout for more papers from your teams.

I also talk a bit about how I think Snapshot Isolation, combined with strong consistency, is a sweet spot in the trade-off space. Stronger levels make reasoning about performance a lot harder, and weaker levels make reasoning about concurrency a lot harder (without much perf win)

And how we can make sure we celebrate Max and Snuffles' birthdays atomically and durably.

This talk is a lot about scale and active/active, but scale isn't the only goal: we designed DSQL to be simple and easy to use for applications of all sizes, while making it easy to bring a lot of existing application code. Check it out: https://aws.amazon.com/rds/aurora/dsql/
