How to design isolated DB for each client where each client has specific credentials

Working with Data
1

Hi,
We are trying to have an isolated DB for each client with the same host, we are handling all the clients from a single service(don’t have service for each client).
Criteria which we want to consider is:

  1. Each client DB should have different credentials for access
  2. For every new request, we don’t want to create a new mongo client object
    Is it possible to connect to host with admin credentials and later connecting to DB with client specific credentials based on application we get?

Thanks
