[SIP-195] Support SQL-based querying on MongoDB. #36844
Description
Please make sure you are familiar with the SIP process documented
here. The SIP will be numbered by a committer upon acceptance.
[SIP] Proposal for Supporting SQL-based querying on MongoDB.<title>
Motivation
Apache Superset provides a rich SQL-based analytical experience, but it currently lacks a connector for NoSQL databases such as MongoDB. Providing SQL-based querying support for MongoDB would significantly improve Superset’s usability, lower the learning curve for analysts, and enable more real-time analytics directly on MongoDB data.
Proposed Change
I have created a DB API 2.0–compliant project that allows users to query MongoDB using SQL. A SQLAlchemy dialect has already been implemented in the project. The remaining work is to add MongoDB as a new engine in db_engine_specs, and to complete the unit tests and documentation.
Project space: https://github.com/passren/PyMongoSQL
The proposed connection string would be:
mongodb://<user>:<password>@<host>:<port>/<database>?mode=superset
mongodb+srv://<user>:<password>@<host>:<port>/<database>?mode=superset
New or Changed Public Interfaces
No changes to Public Interfaces
New dependencies
PyMongoSQL is required as a dependency and is maintained by me. I am also the author of PyDynamoDB which is the connector to dynamodb for superset, which follows a similar design and maintenance model. The license is MIT.
pip install pymongosql
Migration Plan and Compatibility
No migration is required. PyMongoSQL supports both SQLAlchemy 1.x and 2.x.
Rejected Alternatives
No

Can this be added into projects board and assign a SIP# so that I can work on it?

I'm inclined to think we don't need a SIP for this at all if it's just adding/supporting a new DB. It's just one more on the pile :)
@betodealmeida may have advice here. I'd say feel free to open the PR in draft mode either way!
As for the future of supporting NoSQL databases in general: there is SO MUCH foundational work to making this possible, and needs to be broken down significantly in more SIPs. But we want to do it eventually.
For example

@rusackas PR was created for this SIP. Would you take time to review it? Thank you.

Yeah, no need to sipify this! 😊

#37307 is already merged, and this didn't really need a SIP. Better late than never closing this one :D
