How do I stream change data capture (CDC) events to Google Cloud Pub/Sub?

In this guide, we will demonstrate how to set up a Google Cloud Pub/Sub topic and subscription to stream change data capture (CDC) events using Pulumi. Google Cloud Pub/Sub is a messaging service that allows you to send and receive messages between independent applications.

We will create a Pub/Sub topic where CDC events will be published and a subscription to receive these events.

import * as pulumi from "@pulumi/pulumi";
import * as gcp from "@pulumi/gcp";

// Create a Pub/Sub topic
const topic = new gcp.pubsub.Topic("cdc-topic", {
    name: "cdc-topic",
});

// Create a Pub/Sub subscription
const subscription = new gcp.pubsub.Subscription("cdc-subscription", {
    name: "cdc-subscription",
    topic: topic.name,
    ackDeadlineSeconds: 20,
    pushConfig: {
        pushEndpoint: "https://example.com/push-endpoint", // Replace with your endpoint
    },
});

// Export the topic and subscription names
export const topicName = topic.name;
export const subscriptionName = subscription.name;

Key Points

• We created a Pub/Sub topic named cdc-topic which will receive CDC events.
• We set up a Pub/Sub subscription named cdc-subscription to listen to the topic.
• The subscription has a push configuration to send messages to a specified endpoint.

Summary

In this example, we demonstrated how to use Pulumi to create a Google Cloud Pub/Sub topic and subscription for streaming change data capture (CDC) events. The topic serves as the destination for CDC events, while the subscription listens to the topic and pushes messages to a specified endpoint. This setup enables real-time data processing and integration with other systems.
