RDS MySQL Load Testing with Sysbench
Sometimes you need to do a load test on MySQL Database to test Auto-Scaling for example. I found a very useful tool called Sysbench that I will present in this article.

Tracking down high CPU Utilization on Amazon Aurora PostgreSQL
QPM is available on Amazon Aurora PostgreSQL version 10.5-compatible (Aurora 2.1.0) and later and can be enabled in production (minimal overhead) and or enabled/disabled against your test working-sets with tools such as sysbench. I highly recommend turning this on under your test environments and also practice plan evolution (reviewing and approving plans) before applying QPM in production. Once applied to production a periodic review will be necessary to see if the optimizer has found better plans with a lower cost estimate that needs to be approved.

My computer keeps freezing after a while. How can I troubleshoot what's the cause?
Benchmark tools like sysbench can be used to identify temperatur issues since they put some reproducible load on your machine https://github.com/akopytov/sysbench

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.
