Managing Data Dependencies in Cloud-Based Big Data Pipelines: Challenges, Solutions, and Performance Optimization Strategies

Abstract

Cloud-based big data pipelines have become a crucial component in modern data-driven applications, enabling efficient processing, storage, and analysis of massive datasets. However, managing data dependencies within these pipelines presents significant challenges, including data consistency, latency, fault tolerance, and resource allocation. The complexity increases due to distributed environments, heterogeneous data sources, and dynamic workloads. This paper provides a comprehensive analysis of the key challenges associated with data dependency management in cloud-based big data pipelines. We explore existing solutions, including dependency-aware scheduling, lineage tracking, and data orchestration techniques, and assess their effectiveness in addressing consistency and performance concerns. Additionally, we discuss performance optimization strategies such as caching, speculative execution, and adaptive resource provisioning to mitigate latency and enhance fault tolerance. By evaluating state-of-the-art methodologies and emerging trends, this study aims to provide insights into designing more efficient and resilient big data pipelines. Our findings suggest that integrating machine learning-driven optimization techniques and leveraging serverless architectures can further improve data dependency management in cloud environments. The paper concludes with future directions, emphasizing the need for more adaptive, scalable, and intelligent approaches to data dependency handling.
