Before you get Started

1. Create a Hasura Cloud account
2. Please ensure you have the DDN CLI and Docker installed
3. Create a supergraph
4. Create a subgraph

The steps below explain how to Initialize and configure a connector for local development. You can learn how to deploy a connector — after it's been configured — here.

Using the Azure Cosmos DB for NoSQL connector

Step 1: Authenticate your CLI session

ddn auth login

Step 2: Configure the connector

Once you have an initialized supergraph and subgraph, run the initialization command in interactive mode while providing a name for the connector in the prompt:

ddn connector init <connector-name> -i

Step 2.1: Choose the hasura/azure-cosmos from the list

Step 2.2: Choose a port for the connector

The CLI will ask for a specific port to run the connector on. Choose a port that is not already in use or use the default suggested port.

Step 2.3: Provide the env vars for the connector

Name	Description	Required	Default
AZURE_COSMOS_KEY	Primary/Secondary key asssociated with the Azure Cosmos DB for NoSQL	Yes	N/A
AZURE_COSMOS_ENDPOINT	Endpoint of the Azure Cosmos DB for NoSQL	Yes	N/A
AZURE_COSMOS_DB_NAME	Name of the Database	Yes	N/A
AZURE_COSMOS_NO_OF_ROWS_TO_FETCH	Maximum number of rows to fetch per container to infer the schema. (Optional)	No	100

Step 3: Introspect the connector

ddn connector introspect <connector-name>

This will generate a configuration.json file that will have the schema of your Azure Cosmos DB for NoSQL.

Step 4: Add your resources

ddn connector-link add-resources <connector-name>

This command will track all the containers in your Azure Cosmos DB for NoSQL as Models.
