[EPIC] MongoDB Engines General Availability

[dpetrick]

This epic is representing the collection of work items needed for integrating an MVP of MongoDB into major parts of the engines.

Client integration overview (anything migration CLI, Studio, TS/Go client) is not covered and will reside in separate issues, same goes for documentation efforts.

If something is not linked as a ticket, it means it wasn't done yet but will be in time.

Datamodel:

• [x] Add MongoDB datasource to accepted datasources.
• [ ] https://github.com/prisma/prisma-engines/issues/1595

Introspection engine:

• [x] Reject MongoDB introspection with a comprehensible error message.
• [ ] Implement introspection for JSON schema + non-schema cases (specifics to be determined).

Migration engine:

• [x] Implement minimal migration engine connector for MongoDB
• [ ] Implement minimal constraint migrations (@unique, @@unique).
• [ ] Implement migration engine support (specifics to be determined).

Query engine:

• [x] Set up connector skeleton.
• [x] Implement basic write interface.
• [x] Implement basic read interface.
• [x] Create QE rust integration test harness.
• [x] https://github.com/prisma/prisma/issues/9014
• [ ] https://github.com/prisma/prisma-engines/issues/2063
• [x] Disable query raw API https://github.com/prisma/prisma-engines/pull/2087
• [x] https://github.com/prisma/prisma/issues/8266
• [ ] GroupBy isn't fully functional.
• [ ] Implement missing feature flags:
  • [ ] orderByRelations
  • [ ] orderByAggregateGroup
  • [ ] filterJson
  • [ ] selectRelationCount

FYI: Just disconnected this from the milestone and the board since it's cumbersome to keep two similar issues in sync. We'll use this issue for public tracking: https://github.com/prisma/prisma/issues/1277
