mongodb-integration-adapter

[ShayMichaely15]

According the following blog, I have 3 questions:
https://blogs.sap.com/2020/07/23/connecting-to-mongodb-server-from-sap-cloud-platform-integration-using-camel-mongodb-component/

First question :
That mean that the connection to the Mongodb database is hard coded in the adapter ?
So, if I have 3 databases dev, test Prod, I need 3 adapters.

Second question :
My database need a user and password.
So I have to to use something like that : mongodb://username:password@localhost/mydb
Is it correct ? that mean that my user/password are also hard coded. Is there a security risk there ?

Third question :
My database is on premise. So, I guess I need to use the cloud connector. how do it interface with the adapter ?
