The MongoDB BI Connector has been enhanced to remove manual management issues of sharing and updating schema files by storing them in the MongoDB database itself. This allows for seamless sharing and modification of schemas between different personas, eliminating the need for tracking and versioning. The new feature enables users to upload DRDL mapping to a MongoDB collection using mongodrdl, providing a unique schema ID and name for the uploaded schema. With this enhancement, users can now start the BI Connector using a custom schema, making it easier to generate dashboards without performing ETL operations.
