I wonder how would one douse investors concern of having Open Source product like ArangoDB, and AWS effectively eating their lunch if/when wide adoption comes?

Congratulations on the funding btw! I'm a happy and grateful user.

The database market will all its competition is definitely challenging. I have no doubt AWS will increase their database market share over time. The good thing about this competition is that it is forcing all vendors to be innovative and to find (more) USPs.

AWS DocumentDB seems to be pretty much tied to the MongoDB API right now... So At the moment this will somewhat limit its functionality. However, they will not stand still and probably also extend into the multi-model space at some point. Apart from that, not everyone will be willing to pay for DocumentDB or have their data located in Amazon datacenters.

"AWS DocumentDB seems to be pretty much tied to the MongoDB API"

I could imagine that they didn't build DocumentDB from the ground up.

DocumentDB is probably just a MongoDB compatible API for one of their base services (S3 or DynamoDB).

As far as I know, they build Serverless Aurora on top of S3, with the help of S3 select. So they will probably just create another custom-DB compatible API if they have the impression that this custom DB becomes the next big thing.

Exactly, AWS DocumentDB is only MongoDB API-compatible, but it's not using any MongoDB components.

It's an implementation of its own, leveraging many the base building blocks and infrastructure Amazon has created.

DocumentDB is currently tied to the MongoDB 3.6 API, that means all the transactional extensions MongoDB has added recently is not present in DocumentDB (yet).

AFAIK MongoDB Atlas still earns quite a bit of money, despite the 3.6 API compatible AWS DocumentDB.
