Java: Message Brokers (Kafka)

Kafka allows implementing the Saga pattern by coordinating distributed transactions through events.

In distributed systems, transactions span multiple services. The Saga pattern breaks a transaction into a series of smaller, atomic steps, each with a compensating action if it fails. Kafka facilitates this by using events to trigger each step. For example, in an e-commerce application, placing an order might involve reserving inventory, charging payment, and updating delivery status. Each step can produce and consume Kafka events, ensuring the entire transaction is eventually consistent.
