MongoDB connection

MongoDB is a NoSQL database designed to store and retrieve unstructured or semi-structured data using BSON documents.

Prerequisites

When you create a MongoDB connection in Prophecy, access permissions are tied to the credentials you use. This is because Prophecy uses your credentials to execute all data operations, such as reading from or writing to collections.

To fully leverage a MongoDB connection in Prophecy, you need the following MongoDB permissions:

• Read from the collection defined in the connection
• Write to the collection defined in the connection

Feature support

The table below outlines whether the connection supports certain Prophecy features.

Feature	Supported
Read data with a Source gem	Yes
Write data with a Target gem	Yes
Browse data in the Environment browser	Yes

Connection parameters

To create a connection with MongoDB, enter the following parameters:

Parameter	Description
Connection Name	Name to identify your connection
Protocol	Protocol to use to communicate to the database Example:mongodb+srv for cloud-hosted clusters
Host	Where your MongoDB instance runs Example:cluster0.<cluster-name>.mongodb.net for cloud-hosted clusters
Username	Username for your MongoDB instance
Password (Secret required)	Password for your MongoDB instance
Database	Default database for reading and writing data
Collection	Collection to use for the connection

Sharing connections within teams

Connections in Prophecy are stored within fabrics, which are assigned to specific teams. Once a MongoDB connection is added to a fabric, all team members who have access to the fabric can use the connection in their projects. No additional authentication is required—team members automatically inherit the access and permissions of the stored connection credentials.

caution

Be mindful of the access level granted by the stored credentials. Anyone on the team will have the same permissions—including access to sensitive data if allowed.

To manage this securely, consider creating a dedicated fabric and team for high-sensitivity connections. This way, only approved users have access to those credentials.

Fetching data

Prophecy fetches data from MongoDB connections in the following ways:

• When you browse a MongoDB connection in the Environment browser, Prophecy fetches data on demand as you expand folders. You can manually refresh the Environment browser to see updated files.

• When a pipeline runs, Source gems will read the latest available version of the data. Keep in mind that schema evolution may or may not be picked up automatically depending on the type of Source gem used.
