Java: Message Brokers (Kafka)

Sagas coordinate distributed transactions by breaking them into a series of local transactions.

In distributed systems, like microservices, achieving strong consistency is complex. Sagas offer a solution by executing a sequence of local transactions that are coordinated using Kafka events. If a step fails, compensating transactions are triggered. For instance, in an e-commerce system, an order service might initiate a saga that reserves inventory, charges payment, and confirms shipment, using compensating actions for failure.
