jhult opened a new issue #17291:
URL: https://github.com/apache/superset/issues/17291


   A clear and concise description of what the bug is.
   
   #### How to reproduce the bug
   
   ```
   
/usr/local/lib/python3.8/site-packages/sqlalchemy/dialects/oracle/base.py:1409: 
SAWarning: Oracle version (19, 13, 0, 1, 0) is known to have a maximum 
identifier length of 128, rather than the historical default of 30. SQLAlchemy 
1.4 will use 128 for this database; please set max_identifier_length=128 in 
create_engine() in order to test the application with this new length, or set 
to 30 in order to assure that 30 continues to be used.  In particular, pay 
close attention to the behavior of database migrations as dynamically generated 
names may change. See the section 'Max Identifier Lengths' in the SQLAlchemy 
Oracle dialect documentation for background.
   ```
