What version of MongoDB is used by Azure CosmosDB? How can I check the version? - azure-cosmosdb-mongoapi

I'm trying to figure out what version of MongoDB is used by CosmosDB?
Tried checking out azure cosmosdb portal for more information but there is no specific version mentioned on it.

From this link:
The Azure Cosmos DB's API for MongoDB is compatible with MongoDB
server version 3.2 by default. The supported operators and any
limitations or exceptions are listed below. Features or query
operators added in MongoDB version 3.4 are currently available as a
preview feature. Any client driver that understands these protocols
should be able to connect to Azure Cosmos DB's API for MongoDB.

In modern Azure Portal UI they display the version of your Cosmos DB in the Overview section:

MongoDB community edition for SAAS based application

We are going to develop a SAAS based application using NoSQL (Preferably MongoDB community edition). When we download the community edition we observed that the MongoDB license got changed to SSPL. And it highlighted that we cannot modify the server code and cannot run MongoDB as a service.
Hence I just wanted to confirm here that, we don't do any change in the server code, we do only store data in MongoDB and host them in a cloud environment and make our web application as a service to the customers (SAAS). So it wont violate anything in the SSPL right.

How to integrate Mongodb Atlas with cloud integration platform such as mulesoft?

So recently I started studying MongoDB Atlas. So just wanted to know how I can integrate that cloud database to any cloud integration tool such as MULESOFT. Do I have to create an API from MongoDB Stitch and then integrate it or am I missing something?
Help would be much appreciated.
Specifically for Mule Runtime (MuleSoft is the company name, not a product) you can use the MongoDB connector to connect an application to a MongoDB database. For Atlas compatibility I have seen it is recommended to set the authenticationDB configuration.

Heroku mLab MongoDB add-on vs MongoDB Atlas

I am using MongoDB Atlas with my Heroku app.
I have seen that there is an mLab MongoDB add-on on Heroku, as mLab is part MongoDB Atlas now, was is the advantage of using this add-on ?
Moreover, the add-on looks like a more expensive solution than MongoDB Atlas...
You should use the new MongoDB Atlas Heroku app. mLab heroku app will be deprecated when the migration done, see the doc from migrating from mLab to Atlas
MongoDB plans to build an integration between MongoDB Atlas and Heroku. You will be able to continue to use mLab via its add-on at Heroku until the new integration is available.
Now this add on feature is no more useful as mlab has already been acquired by MongoDB.
Earlier the purpose of this feature was that the mLab Add-on used to be co-located with your application in case you have selected this option and could help in reducing the latency of your application as mlab was available primarily in US regions.
But now mlab has been acquired by MongoDB and you can deploy Atlas cluster in the same region of your application to reduce the latency.
I hope this answer your question.

Compatible Scala driver for Amazon DocumentDB

Do you know a Scala driver to MongoDB, which is also compatible to Amazon DocumentDB? In theory they all should be compatible, I am interested what works in practice. In particular, I plan to use reactivemongo.
https://mongodb.github.io/mongo-scala-driver/ is compatible with Amazon DocumentDB.
Main point is to properly use the RDS certificate (cannot be tested locally w/o tunnel), as indicated in the documentation.
mongodb.uri = "mongodb://${USER}:${PASSWORD}#${DOCDB_CLUSTER}${AWS_REGION}.docdb.amazonaws.com:27017/${DB_NAME}?ssl=true&keyStore=file:///path/on/local/fs/to/rds-ca-2015-root.jks&keyStorePassword=${KEYSTORE_PASS}&keyStoreType=JKS"

MongoDB and Mongolab.com

Recently I discovered the power of noSQL database MongoDB. After a lot of trial and error I was able to install it on my pc along with wampserver. Its running smoothly. Now the question I would like to ask is, that if I want to integrate the MongoDB service provided by Mongolab on my shared hosting plan, is there any class available that helps me connect to the database? Like a php class version of the driver for php and mongodb. As it is not possible to install the driver on my hosting, because of no root access. So is there a raw class available as an alternative to the driver dll?
If you can't install the driver, then the REST interface provided by MongoLab is your best bet - any language that can send/receive a HTTP request can use REST:
