FAULT TOLERANCE IN MODERN DATA ENGINEERING: CORE PRINCIPLES AND DESIGN PATTERNS FOR BUILDING RELIABLE AND RESILIENT DATA PIPELINE ARCHITECTURES

Abstract

In the era of big data and distributed computing, fault tolerance has become indispensable for building reliable and resilient data pipelines. These pipelines are crucial for processing, analyzing, and extracting insights from large datasets but are prone to failures caused by resource constraints, cascading errors, and inconsistencies in distributed systems. This paper explores fault tolerance in modern data engineering, focusing on the transition from monolithic to microservices-based architectures. By leveraging the modularity of microservices, organizations can enhance fault isolation, scalability, and recovery. The study reviews prominent fault-tolerant frameworks such as Apache Kafka, Flink, and Spark, evaluating their recovery mechanisms and highlighting fault-tolerant design patterns like circuit breakers, retries, and bulkhead isolation. Additionally, it examines real-world implementations from industry leaders such as Netflix and Uber. Emerging trends, including serverless architectures, AI-driven fault detection, and chaos engineering, are discussed alongside challenges such as inter-service communication failures and resource overheads. Concluding with a taxonomy of fault-tolerant strategies and future research directions, this paper serves as a comprehensive guide for designing robust and efficient data pipelines.
