Google Cloud Pub/Sub — Messaging¶
GCPPub/SubMessagingStreaming 5 min read
Pub/Sub topics, subscriptions, exactly-once delivery and BigQuery export.
Basics¶
gcloud pubsub topics create orders
gcloud pubsub subscriptions create order-processor \
--topic=orders --ack-deadline=60 \
--enable-exactly-once-delivery \
--dead-letter-topic=orders-dlq --max-delivery-attempts=5
Push vs Pull¶
- Pull — subscriber pulls messages, controls throughput
- Push — HTTP POST to endpoint, ideal for Cloud Run/Functions
BigQuery Subscription¶
gcloud pubsub subscriptions create bq-export \
--topic=orders --bigquery-table=proj:dataset.orders \
--use-topic-schema --write-metadata
Zero-code streaming to data warehouse.
Summary¶
Pub/Sub = fully managed messaging with global reach. Exactly-once + BQ subscription = strong foundation.
