Note: Please contact us at [email protected] to enable this Source Connector.
CosmosDB 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 CosmosDB table using your CosmosDB username and password.
We use the Azure Cosmos DB API for MongoDB. More information can be found here.


You need to have a CosmosDB 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 CosmosDB Source Connector

Step 1: After selecting + New Connector, under the System prompt, click CosmosDB.
Step 2: Enter a Connector Name.
Step 3: Select Source Connector. Selecting this allows you to ingest data from CosmosDB.
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.
Step 8: Provide the name of the collection that 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:
Tip: The schema for this Source Connector is defined by the first 10 documents in the collection.
