A diagnostic guide for JetStream pull consumer lag: recognize growing pending counts, identify whether processing, AckWait, fetch config, or storage is the cause, and apply the matching fix.
Learn how to set up a Vert.x clustered Event Bus, register custom codecs, enforce security headers, and monitor cluster health for reliable inter‑service communication.
Want to horizontally scale message workers without a load balancer? JetStream pull consumers let you batch‑fetch, ack, and distribute work across workers, giving you flow control and at‑least‑once delivery. Learn how to set up a pull consumer, run workers, and avoid duplicate processing.
Set up JetStream durable consumers with explicit acknowledgements so message processing survives crashes — and learn why idempotent handlers are non-negotiable.
Learn how RabbitMQ dead-letter exchanges capture failed messages for debugging and retry workflows. A practical guide to configuring DLX with TTL and routing keys.
JetStream pull consumers let subscribers fetch batches at their own pace with explicit acks, giving you backpressure, at-least-once delivery, and queue-style scaling without extra infrastructure.
Learn how to implement Apache Pulsar Shared Subscriptions to horizontally scale message consumption across multiple workers and improve system throughput.
Learn how to implement Apache Pulsar Shared Subscriptions to distribute message processing across multiple consumers and scale throughput horizontally.
Stop losing messages when subscribers go offline. Learn how to use NATS JetStream to implement durable persistence and at-least-once delivery guarantees.
