ABSTRACT
In today’s data-driven financial ecosystem, reliability is the cornerstone of every data pipeline. Regulatory frameworks such as GDPR, CCPA, SOX, and Basel demand not only accuracy and timeliness but also full auditability and compliance across the data lifecycle. Traditional pipelines often fail under the weight of these requirements, leading to operational risks and costly penalties.
This article introduces a comprehensive framework for building reliable, scalable, and compliant data pipelines, tailored for high-stakes environments like banking and financial services. It explores architectural principles such as immutable raw zones, metadata-driven governance, and policy-based access control, combined with modern orchestration tools like Apache Airflow and distributed processing engines such as Apache Spark and Flink.
The framework integrates AI/ML capabilities for anomaly detection, PII classification, and predictive compliance, ensuring proactive risk mitigation. Real-world benchmarks demonstrate significant impact—reducing regulatory reporting time from 3 days to 2 hours, achieving 98% pipeline uptime, and delivering zero audit findings across multiple reviews.
By embedding compliance into the engineering lifecycle, this guide empowers data engineers to design pipelines that prioritize trust, traceability, and resilience, setting a new standard for reliability in regulated industries.
In today’s data driven world, reliable data pipelines are the lifelines of analytics, reporting and AI. When pipelines fail or silently deliver incorrect data, the consequences ripple across decision-making, compliance, and customer experience. This article offers a practical guide for data engineers to design, build and maintain reliable, scalable and resilient pipelines using modern tools and techniques.
