Thanks for sharing. They validated exactly what I said was of concern:

- loss of atomicity and transactions.

- tons of custom tooling to work around limitation of custom sql (knowing which operations are allowed and consistent).

- GitHub was able to operate for almost a decade on a single MySQL instance, and it’s not clear they really hard to change.

Etsy said this was a huge problem and took 5 years and thousands of PRs to resolve.
