To fetch the metadata from MongoDB to OpenMetadata, the MongoDB user must have access to perform `find` operation on collection and `listCollection` operations on database available in MongoDB.
- **MongoDB Connection Details**: Choose between MongoDB Connection String and MongoDB Connection Values to authenticate with your mongodb cluster.
- **Connection URI**: MongoDB connection string is a concise string of parameters used to establish a connection between an OpenMetadata and a MongoDB database. For ex. `mongodb://username:password@mongodb0.example.com:27017`.
- **Username**: Username to connect to Mongodb. This user must have access to perform `find` operation on collection and `listCollection` operations on database available in MongoDB.
- **Password**: Password to connect to MongoDB.
- **Host Port**: The hostPort parameter specifies the host and port of the MongoDB. This should be specified as a string in the format `hostname:port`. E.g., `localhost:27017`.
- **databaseName**: Optional name to give to the database in OpenMetadata. If left blank, we will use default as the database name.
