Extracting Column Descriptions from MySQL/PostgreSQL Data Sources with Connectors Using SQLAlchemy

Original Slack Thread

Hi team, I have a query about description tab in the dataset. When we are ingesting metadata from datasource from mysql/postgresql, how column wise description is extracted from the datasource?

Connectors are using sqlalchemy library to get this information. You can check code at https://github.com/datahub-project/datahub/blob/master/metadata-ingestion/src/datahub/ingestion/source/sql/sql_common.py#L738

Thanks! It was very helpful! :raised_hands:
