Note: Please contact us at to enable this Source Connector.

MongoDB is a NoSQL document store which stores data in a JSON-like format without a specified schema. This Source Connector allows you to read documents from a single collection and ingest them into Osmos.

This Source Connector can pull from a MongoDB table using your MongoDB username and password.


You need to have a MongoDB instance that will accept connection attempts from the following fixed IP addresses:,

The collection must be non-empty as the first 10 documents in the collection are used to infer the schema.

You must have a connection string provided by the database from which to connect your DB.

Creating a MongoDB Source Connector

Step 1: After selecting + New Connector, under the System prompt, click MongoDB.

Step 2: Enter a Connector Name.

Step 3: Select Source Connector. Selecting this allows you to ingest data from MongoDB.

Step 4: Provide the connection string, but leave out the username and password.

Example: mongodb://host1[:port1][,...hostN[:portN]][/[defaultauthdb][?options]]

Step 5: Provide your username.

Step 6: Provide the password associated with the username above.

Step 7: Provide the name of the database that contains the collections you want to read from.

Tip: If you are trying to access a database that is behind a firewall, please ensure that the following Osmos IP addresses are allowed to access the database. Osmos uses these fixed IP addresses to access your sources and destinations:

Step 8: Provide the name of the collection that you want to read from.

Tip: The schema for this Source Connector is defined by the first 10 documents in the collection.

Advanced Options

Header Normalization

The source file may have characters at the start or end that includes spaces, tabs, carriage returns and line endings. You can choose to keep all characters from the source or remove all whitespace. Select one of the options:

  1. Don't normalize headers. Use headers exactly as they appear in the source: If this option is selected, we will retain all characters from the source file.

  2. Remove extra whitespace and other common untypable characters from headers: If this option is selected, we remove all whitespace (spaces, tabs, carriage returns, line endings) at start/end.
