Why don't you tell us how you really feel about MySQL? I'm sensing mixed 
feelings here.

Subject: Why am I seeing references to MySQL?

I am just getting started with Airflow.

It's been a real pain in the ass to configured, as the documentation is 
confusing and misleading.

Question:

Why are there references to MySQL in the airflow.cfg?

$grep mysql airflow.cfg
broker_url = sqla+mysql://airflow:airflow@localhost:3306/airflow
result_backend = db+mysql://airflow:airflow@localhost:3306/airflow

What are these two settings?

Is it safe to comment them out?
What are they for?

I don't have MySQL installed on localhost.  Was this a requirement that was 
missed in the documentation?

We don't use MySQL in our organization and never will, because:
1. It's not an open source database
2. it's historical hostility and bad acts against open source
3. it's not a relational database, or at best, it's a half ass relational 
database where to be truly relational you have to bend over backwards in 
configuration and code to get it to work relationally

Can someone please reach the dev team to take this crap out?

What am I supposed to do with these settings?
