What difference between apache-airflow[mysql] and apache-airflow-providers-mysql

[HuFei2017]

As the title says, I get troubles in the learning process.
I wanna know what difference between apache-airflow[mysql] and apache-airflow-providers-mysql, which decide what I should do with pip.

apache-airflow-providers-mysql is a stand-alone package which does not include "airflow core" it includes only content of airflow/providers/mysql. You can learn more about providers here:
http://airflow.apache.org/docs/apache-airflow-providers/

On the other hand apache-airflow[mysql] will install "core airflow" with additional dependencies required to run Airflow with mysql database as backend and - if I'm not mistaken - it will also install apache-airflow-providers-mysql.

And if I correctly understand both commands should give similar result:

pip install apache-airflow[mysql]
# or
pip install apache-airflow
pip install apache-airflow-providers-mysql

@potiuk can you confirm?

Yes. Those two are equivalent.

The updated documentation out extras and additional packaged (will be released in 2.0.1) can be found here. You can read more information there about extras/provider packages: https://github.com/apache/airflow/blob/master/docs/apache-airflow/extra-packages-ref.rst.
