A Critical Analysis of Apache Kafka's Role in Advancing Microservices Architecture: Performance, Patterns, and Persistence
Keywords:
Event-Driven Architecture, Microservices, Apache Kafka, Distributed SystemsAbstract
Purpose: This article critically analyzes the strategic adoption of Apache Kafka as a foundational event streaming framework within Microservices Architecture (MSA), evaluating its impact on system performance, architectural design, and operational complexity in modern distributed computing.
Methodology: The research synthesizes academic literature and industry best practices, detailing Kafka’s distributed log architecture (brokers, topics, partitions) and its alignment with Event-Driven Architecture (EDA) principles. A systematic review is conducted on key microservices patterns—Event Sourcing, Saga, and CQRS—to model inter-service communication and distributed data consistency. The study also investigates the empirical trade-offs associated with performance tuning and system governance.
Findings: Kafka provides an essential backbone for achieving high-throughput, low-latency, and decoupled services, empirically handling millions of events per second. The distributed log structure inherently supports complex patterns necessary for distributed data management, such as the Saga pattern for transactional integrity. However, its adoption introduces significant operational overhead related to schema evolution management, the complexities of achieving eventual consistency, and the necessity for robust distributed observability solutions like tracing and correlated logging.
Originality: This work offers a comprehensive framework for design and deployment, moving beyond basic integration to emphasize the challenges of governance and stateful stream processing, thereby supporting the strategic architectural decisions required for an 8000+ word manuscript.
