Well, this story is better told by the guy who broke it, John De Goes.
The TL;DR is that MongoDB will be shipping PostgreSQL as its "legacy BI connector" in version 3.2, using PostgreSQL+Multicorn FDW as a wrapper to connect SQL-based BI systems to Mongo.
I have two thoughts about this:
- Welcome to the PostgreSQL community, MongoDB staff!
- Multicorn? I mean, not that Multicorn isn't great, but don't you think you should be using a C-based FDW driver for performance?
Anyway, hopefully the folks at MongoDB will put in a talk at pgNYC about this. We're always keen to hear about creative uses of FDWs, and if this isn't one, I don't know what is.
