1. Automated Data Processing with MongoDB Atlas Event Triggers


    To set up automated data processing within MongoDB Atlas using Pulumi, you would utilize the MongoDB Atlas provider to create an Event Trigger. Event Triggers in MongoDB Atlas can call external services or functions in response to database events such as inserts, updates, deletes, or via a scheduled CRON job. These triggers can be used to automate certain workflows or react to data changes in real-time.

    In your Pulumi program, you would define a MongoDB Atlas Event Trigger resource, specifying the details of the trigger such as the related database/collection, event type, and the function to be executed when the trigger is activated.

    Let's create a Pulumi program that sets up an Event Trigger in MongoDB Atlas. This program will create a trigger which will execute a function whenever a document is inserted into a specified collection.

    For this example, we will assume that you already have set up a MongoDB Atlas project and have the appropiate Mongo Atlas API keys configured with Pulumi.

    Here’s how you can create a simple Event Trigger using Pulumi in Python:

    import pulumi import pulumi_mongodbatlas as mongodbatlas # Create MongoDB Atlas Event Trigger event_trigger = mongodbatlas.EventTrigger("myEventTrigger", project_id="your-atlas-project-id", # Replace with your MongoDB Atlas project ID app_id="your-atlas-app-id", # Replace with your MongoDB Atlas Application ID config_collection="your-collection-name", # Replace with the collection you want to watch config_database="your-database-name", # Replace with your database name type="DATABASE", # Type of the trigger, DATABASE for collection-level changes config_operation_types=["INSERT"], # List of operation types to trigger on config_service_id="your-atlas-service-id", # Replace with your service ID # The function that should run when the trigger is executed, should already exist function_id="your-function-id", # Replace with your MongoDB Atlas function ID ) pulumi.export('trigger_id', event_trigger.id)

    In this program:

    • We imported the required Pulumi modules for MongoDB Atlas.
    • We created an EventTrigger resource. The project_id, app_id, config_collection, config_database, config_service_id, and function_id should be replaced with your actual MongoDB Atlas configuration.
    • type specifies that this is a database trigger.
    • config_operation_types is a list of the operations that will activate the trigger. In this case, the trigger will activate for INSERT operations.
    • The function_id is the MongoDB Atlas Function's unique identifier that will be executed when the trigger is fired.
    • Finally, we export the trigger's ID, which can be used to reference the trigger in other parts of our infrastructure or applications.

    This is a very basic setup. More advanced configurations can include setting up config_match to filter events, setting up event_processors to handle events, and many other options depending on your specific use case.

    Make sure to check the official Pulumi MongoDB Atlas provider documentation for more details on configuring different types of triggers and their properties:

    Remember to set your MongoDB Atlas API keys as environment variables, or configure them through the Pulumi configuration system to authenticate your requests.
