    Google PubSub connector details

    The Google Cloud Pub/Sub materialization connector continuously publishes updates from Estuary collections to Pub/Sub topics in your Google Cloud project. It enables real-time event streaming pipelines that can feed downstream consumers, analytics systems, or microservices.

    • Continuous delivery: Streams data updates from Flow collections to Pub/Sub topics in real time
    • Authentication options: Supports OAuth (via the Flow web app) or Service Account credentials for manual setup
    • Automatic topic handling: Can create topics and default subscriptions automatically for ease of use
    • Multiplex publishing: Materialize multiple collections into a single Pub/Sub topic with unique identifiers
    • Guaranteed ordering: Publishes messages with ordering keys derived from Flow collection keys to maintain sequence integrity
    • Flexible integration: Compatible with all GCP regions and existing Pub/Sub infrastructure

    💡 Tip: Use this connector to stream Flow data into event-driven applications, trigger workflows in Cloud Functions, or power analytics pipelines through Pub/Sub subscriptions.
