Imagine if they went after Mongo next?

Atlas is a virtual monopoly for Mongo solely due to SSPL, and it has created a ridiculously overpriced ecosystem for hosted and managed services, and tooling around it.

Parking the technical merits to one side, considering the sheer number of devs and early-stage products that are built on Mongo, I'd love for someone to go after them next.



Amazon already have DocumentDB which clones the Mongo API. I don't think its forked though, they just use a barely mongo compatible wrapper around their own db engine.


It's not nearly as compatible as you might think. Interestingly enough, MongoDB's CTO managed RDS at AWS.



True, but it's not quite the same as what they've done with OpenSearch/Elastic. Also, from what I've read, despite claims, the compatibility isn't complete, esp with stuff like aggregations.

There are a few use-cases where you'd want the ability to have a managed/hosted vanilla Mongo setup vs an emulated experience.


Kinda blocked on the compatibility front after the 4.0 API though, eh?


Not if the recent Oracle vs Google supreme court ruling is to be acknowledged.

DocumentDB is to MongoDB 4.0+ as Dalvik runtime was to JVM.

Here is their 4.0 compatibility update: https://docs.aws.amazon.com/documentdb/latest/developerguide...


Time will tell...MongoDB 4.2 APIs are under SSPL

"Amazon DocumentDB implements the Apache 2.0 open source MongoDB 3.6 and 4.0 APIs by emulating the responses that a MongoDB client expects from a MongoDB server, allowing you to use your existing MongoDB drivers and tools with Amazon DocumentDB."

https://aws.amazon.com/documentdb/

IANAL
