How we can use SFDC(Salesforce) as one of the data sources for GE?
Currently GE does not natively support Salesforce as a datasource. If you are interested in experimenting with it using SQLAlchemy you could try something.
GE can use a SQLAlchemy connection string (find an example here):
Then when you run
great_expectations datasource new you can choose “Connection String”.
Now there are absolutely no guarantees this will work - noone has yet tested this to my knowledge but it might?
