Apache Airflow 2 with MySQL Providers

Apache Airflow 2 is an open-source platform that helps with complex workflows. It is designed with modularity at its core. While the “Core” of Apache Airflow offers scheduler functionality for basic tasks, the true potential of Apache Airflow can be experienced with additional packages known as providers.

Providers act as the backbone for extending the features of Apache Airflow. These packages consist of operators, hooks, sensors, and transfer operators. Importantly, providers also support the core functionality of Apache Airflow.

Furthermore, users can install provider packages as per their needs. The Apache Airflow Community actively develops and maintains over 80 provider packages

MySQL Provider Package

All classes associated with the MySQL provider package reside in the `airflow.providers.mysql` Python package. We can easily install this package on an existing Apache Airflow 2 installation using one of these commands:

• Via pip:

  pip install apache-airflow-providers-mysql
• Using poetry:

  poetry add apache-airflow-providers-mysql

To make sure we are using all of the package’s features, we need certain dependencies. So, we can install these by specifying the desired provider packages during installation from PyPI..

For example:

pip install apache-airflow-providers-mysql[amazon]

Now. let’s take a look at how to use `S3ToMySqlOperator’. We can import it into our workflow with this import statement:

from airflow.providers.mysql.transfers.s3_to_mysql import S3ToMySqlOperator

Our experts would like to point out that before using this operator, we have to install the MySQL provider. For backport versions, we have to use this command:

pip install apache-airflow-backport-providers-mysql

Here is an example:

If we run into import errors like “No module named ‘airflow.providers.mysql'” when using the `MysqlOperator`, we have to install the MySQL provider:

pip install apache-airflow-providers-mysql

For Python 3 environments, we have to use:

pip3 install apache-airflow-providers-mysql
