Java: Eventual Consistency (Sagas)

Due to separate databases, distributed systems struggle to coordinate atomic operations.

In a microservices architecture, each service typically has its own database. This separation leads to challenges in coordinating transactions across multiple services, as the atomicity in ACID cannot be guaranteed over distributed systems. For example, in an e-commerce system, if a product sale involves updating the inventory and processing payment, these operations might span different services and databases, making perfect ACID compliance impractical.
