Lola Slade created AIRFLOW-4824:
-----------------------------------
Summary: MySqlHook needs to override DbApiHook.get_uri to pull in
extra for charset=utf-8 during create_engine
Key: AIRFLOW-4824
URL: https://issues.apache.org/jira/browse/AIRFLOW-4824
Project: Apache Airflow
Issue Type: Bug
Components: hooks
Affects Versions: 1.10.3
Reporter: Lola Slade
When using the engine from a MySQLHook in other code (such as Pandas) the
engine returned from the create_engine function is missing the charset=utf-8
This issue was reported here:
[https://stackoverflow.com/questions/46084744/how-to-explicitly-declare-charset-utf8-for-airflow-connections]
{{{{conn = MySqlHook(mysql_conn_id='conn_id')
}}}}{{{{engine = conn.get_sqlalchemy_engine()}}}}
I can see that the code in function *get_uri* in dbapi_hook.py does not use the
charset = utf8 information from the extra section and that mysql_hook.py does
not override the function.
