Pioneering adaptive transaction isolation in cloud-native microservices: A dynamic algorithm achieving optimal consistency-performance balance

Sana, Santosh Kumar (2025) Pioneering adaptive transaction isolation in cloud-native microservices: A dynamic algorithm achieving optimal consistency-performance balance. World Journal of Advanced Engineering Technology and Sciences, 15 (1). pp. 218-234. ISSN 2582-8266

This article introduces a novel dynamic transaction isolation algorithm for cloud-native microservices that automatically adapts isolation levels based on real-time workload analysis and data criticality. Traditional database systems rely on static isolation levels that force an unnecessary trade-off between consistency and performance. The Adaptive Transaction Isolation (ATI) algorithm addresses this dilemma by continuously monitoring system behavior and intelligently selecting appropriate isolation levels for individual transactions. The algorithm incorporates context awareness, predictive modeling, and continuous adaptation to balance consistency requirements with performance needs. Through its four-component architecture—monitoring subsystem, classification engine, decision engine, and execution controller—ATI enables microservices to maintain data integrity while maximizing throughput. Implementation through a lightweight middleware layer integrates seamlessly with existing cloud-native architectures, providing specialized adaptations for microservice environments and cloud-specific optimizations. Real-world implementations across financial services, e-commerce, and healthcare sectors demonstrate significant performance improvements, with ROI typically achieved within 3-9 months. Comprehensive performance evaluations show substantial enhancements in throughput, consistency, latency, and resource utilization compared to static isolation approaches, delivering both technical advantages and measurable business value.
