Messaging terms
Decoupling systems through reliable, async communication
Asynchronous messaging decouples producers from consumers and makes distributed systems more resilient. This category covers message queues, pub/sub patterns, event streaming with Kafka, delivery guarantees, dead letter queues, and the architecture patterns that make event-driven systems robust at scale. When you need services to communicate without depending on each other's availability, messaging is the answer.
Apache Kafka Fundamentals PHP 7.0+
A distributed event streaming platform that stores messages as an immutable ordered log partitioned across a cluster — optimised for high-throughput, durable, replayable event streams rather than traditional task queues.

CQRS Pattern PHP 7.0+
Command Query Responsibility Segregation — separating the write model (commands that change state) from the read model (queries that return data), allowing each to be optimised independently.

Exactly-Once Delivery
Exactly-once delivery ensures each message is processed exactly once — achievable only with coordination between broker and consumer using transactions or idempotent producers.

Saga Pattern
The Saga pattern manages distributed transactions across services using a sequence of local transactions — each step publishes an event, and compensating transactions undo completed steps on failure.

Transactional Outbox Pattern
The Outbox pattern atomically saves domain events to an 'outbox' DB table in the same transaction as business data — a relay then publishes to the message broker, preventing lost events.

Message Ordering Guarantees
Different message systems provide different ordering: Kafka guarantees order within a partition, SQS Standard does not guarantee order, SQS FIFO guarantees order within a message group.
