Tracking down high CPU Utilization on Amazon Aurora PostgreSQL
Hoping something like the zheap storage engine initiative should help us get past these bottlenecks in the future. Until then we may not be able to prevent the bloat but could certainly minimize the impact.

Building an interface (even if there's only one implementation) is always right
Hey, OP here -- it is a bit odd and also possibly immature to be so harsh on MySQL apropos of nothing. That said, I intended more to be pro-Postgres rather than anti-MySQL (it's a great piece of software, other DBs and Postgres learn from it all the time, zheap[0] exists to replicate what they've built, for example).
I also have to admit that I definitely want postgres every time I see MySQL. Maybe I need to read more on just how easy and amazing MySQL can be. Links welcome!

Databases in 2021: A Year in Review
Postgres's dominance is well deserved, of course. My only concerns with it, both are actively worked on, are bloat management (significant for update heavy workloads and programmers used to the MySQL model of rollback segments) and the scaling of concurrency (going over 500 connections). Bloat was taken over by Cybertec[1] after stalling for a bit and is funded (yay), while concurrency was also enhanced out of Microsoft [2]. All in all, an excellent future for our beloved Postgres.

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/.

Want to avoid MySQL but find PlanetScale really appealing
A lot of this is possible thanks to the magic of Vitess.
