Configuring Modin usage
dfsql supports executing queries using Modin for enchanced performance.
By default Modin will be used if it's installed.
To override this behavior and use Pandas set the USE_MODIN environment variable to False or 0 before importing dfsql:
(venv) user:~/mindsdb/dfsql$ export USE_MODIN=0
(venv) user:~/mindsdb/dfsql$ python
Python 3.8.5 (default, Jan 27 2021, 15:41:15)
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import dfsql
>>> dfsql.config.Configuration.as_dict()
{'USE_MODIN': 0}
