한눈에 보기

Pub/Sub is a managed message broker for async communication. Publishers send messages (events), subscribers receive them. Decouples systems (publisher doesn't know subscribers). At-least-once delivery, ordering, filtering. Mastery takes 2-3 weeks. Mid-level practitioners earn 10-15% premium for designing event-driven architectures. Skill adjacent to Kafka, RabbitMQ, and event-streaming patterns.

GCP Pub Sub Messaging이란

Pub/Sub is a managed message broker. Publishers send messages to topics; subscribers receive from subscriptions. Messages are decoupled, publisher doesn't know who's listening. Used for event streaming (user signed up, product viewed, payment processed). At-least-once delivery: if subscriber crashes before acknowledging, message is redelivered. Ordering: within a partition, messages are ordered. Filtering: receive only messages matching criteria.

❓ 자주 묻는 질문

What's the difference between Pub/Sub and Cloud Tasks?

Pub/Sub: broadcast to many subscribers, at-least-once delivery, good for events. Cloud Tasks: point-to-point queue, guaranteed delivery, good for transactional work. Use Pub/Sub for analytics/logging/events, Cloud Tasks for order processing/critical work.

How do I guarantee messages aren't lost?

Pub/Sub guarantees at-least-once delivery (subscribers must ack message). Subscriber crashes before acking? Message redelivered to another subscriber. For exactly-once, implement idempotency on receiver.

Can I order messages?

Pub/Sub guarantees ordering within a partition (same key). If you need global ordering (all messages in order), use a single partition (doesn't scale). For most cases, ordering-per-key is sufficient.

What if a subscriber is slow?

Pub/Sub buffers messages (up to 7 days). Slow subscriber pulls messages at its own pace. Doesn't affect other subscribers. If subscriber disappears, messages eventually purged (7-day default TTL).

How do I debug message failures?

Check Cloud Logging for errors. Use Cloud Trace to see message lifecycle. Create a dead-letter topic: failed messages (after retries) sent there. Inspect dead-letter topic for debugging.

Can I filter messages before receiving?

Yes. Create a subscription with a filter expression (Pub/Sub SQL-like syntax). Subscriber only receives messages matching filter. Reduces bandwidth and processing.
