Azure Functions - Bindings & Triggers with Cosmos DB

Explore the integration between Azure Functions and Cosmos DB.

Understanding the Integration

This page demonstrates how you can use Azure Functions to interact with Cosmos DB. Bindings and triggers allow you to define the flow of data between your function and your database, simplifying development and providing a robust solution for event-driven architectures.

Bindings

Bindings provide a declarative way to define the connection between your function and Cosmos DB. They handle tasks like authentication, schema mapping, and data transformation.

Bindings

Triggers

Triggers initiate the execution of your function. Common triggers for Cosmos DB include HTTP triggers, Timer triggers, and Event triggers.

Triggers

Example Scenario: Updating a Document

Imagine a scenario where an HTTP trigger receives data, and your function updates a specific document in your Cosmos DB container. This is where bindings and triggers shine, automating the entire process.
