Stream Processing with Cloud PubSub and Dataflow Qwik Start GSP903

Overview Google Cloud Pub/Sub is a messaging service for exchanging event data among applications and services. A producer of data publishes messages to a Cloud Pub/Sub topic. A consumer creates a subscription to that topic. Subscribers either pull messages from a subscription or are configured as webhooks for push subscriptions. Every subscriber must acknowledge each message within a configurable window of time. Dataflow is a fully-managed service for transforming and enriching data in stream (real-time) and batch modes with equal reliability and expressiveness. It provides a simplified pipeline development environment using the Apache Beam SDK, which has a rich set of windowing and session analysis primitives as well as an ecosystem of source and sink connectors. Pub/Sub is a scalable, durable event ingestion and delivery system. Dataflow compliments Pub/Sub's scalable, at-least-once delivery model with message deduplication and exactly-once, in-order processing if you use windows and buffering. What you'll do - Read messages published to a Pub/Sub topic - Window (or group) the messages by timestamp - Write the messages to Cloud Storage #gcp #googlecloud #qwiklabs
