Dragonflydb – A modern replacement for Redis and Memcached
I like the redis protocol compatibility and the HTTP compatibility, but from the initial skim through I guess you are using abseil-cpp and the home-grown helio (https://github.com/romange/helio) library.
Could you get me a one liner on the helio library is it used as a fiber wrapper around the io_uring facility in the kernel? Can it be used as a standalone library for implementing fibers in application code?
Also it seems that spinlock has become a defacto standard in the DB world today, thanks for not falling into the trap (because 90% of the users of any DB do not need spinlocks).
Another curious question would why not implement with seastar (since you're not speaking to disk often enough)?

A MySQL compatible database engine written in pure Go
With Vitess likely merging a lot of its binaries into a single unified binary: https://github.com/vitessio/vitess/issues/7471#issuecomment-...
... it would be a wild future if Vitess replaced the underlying MySQL engine with this as long as the performance is good enough.

The challenges of supporting foreign key constraints
Thank you for the compliment!
We recently started adding support for CTEs in Vitess! You can check out https://github.com/vitessio/vitess/pull/14321 if you want to see some technical details of the implementation.
For now, we have added preliminary support by converting them to derived tables internally, but we believe that we need to make CTEs first-class citizens themselves of query planning. Once we make that change, we can look towards supporting recursive CTEs.
This however will take some time, but then, all good things do!

PlanetScale Scaler Pro
This is great news. I strolled around https://github.com/vitessio/vitess/issues/12967.
Are there any public discussions of more trade-offs vitess has to make to enable fks?

What is the best database technology to use to create a new chat app today?
MySQL + Vitess I noticed Slack gets by using MySQL because they're using Vites. From Slack's post (https://slack.engineering/scaling-datastores-at-slack-with-vitess/) it seems like they choose Vites because it facilitated a smooth transition because it's built on top of MySQL.

How can I avoid duplicate API calls in a serverless infra?
This sounds very similar to the connection pooling done by vitess https://vitess.io/.

A lot of this is possible thanks to the magic of Vitess.
