I'm not saying stick with MySQL, but I would say you've probably got a better idea what your app needs and wants, and you should be in control of tech-stack, which it seems you are moving towards enabling you to make changes when as a business you've tested and know it's right.
Correct, we're still keeping MySQL for some things but moving to Elasticsearch for log data. We're using each tool for what they're good at.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
