Understanding EventGrid
EventGrid is a fully managed, global event routing service that ingests and routes events from a wide variety of Azure services and other sources. It's the foundation for building loosely coupled, scalable, and highly available event-driven applications.
Key Concepts
- Triggers: Define how an EventGrid event causes a function to be executed.
- Bindings: Connect your function to other resources (e.g., databases, storage accounts) based on the event data.
- Event Schema: The format of the EventGrid event data.
Example: Simple HTTP Trigger Function
This example demonstrates a basic HTTP trigger function that logs the EventGrid event data to an Azure Log Analytics workspace.
function (event) {
console.log('EventGrid Event:', JSON.stringify(event, null, 2));
return event;
}
To use this function, you would configure an EventGrid trigger to send events to this function. The function would then process the event data and log it to Log Analytics.
Exploring Bindings
Bindings allow you to connect your function to other resources. For example, you could use a storage account binding to save the event data to a blob container, or a database binding to update a database record.
