Abstract: In modern distributed systems, microservices architectures enable independent scaling and rapid development; however, they introduce significant challenges in maintaining data consistency across disparate services and databases. This paper examines the application of reactive design patterns—including event sourcing, CQRS, reactive streams, and the saga and outbox patterns—to optimize real-time data synchronization in microservices. By leveraging asynchronous, non‐blocking communication and eventual consistency models, the proposed approaches offer improved scalability, fault tolerance, and decoupling. The paper discusses the problem statement, details the solution and its practical uses, evaluates its impact on system performance and operational resilience, and outlines the scope and limitations of the approach.

Keywords: Microservices, Reactive Design Patterns, Real-Time Data Synchronization, Event Sourcing, CQRS, Reactive Streams, Saga Pattern, Outbox Pattern, and Change Data Capture
