Abstract: Modern data systems face significant challenges in balancing performance, reliability, and security across increasingly complex data flows. This paper introduces a novel model, Adaptive Data Pipelines with Self-Optimization and Security-Aware Operations (ADPSSO), which enhances static data pipeline approaches by employing reinforcement learning algorithms to dynamically adjust various aspects of data pipelines in terms of both performance and security. The ADPSSO paradigm incorporates a multi-objective optimization framework wherein pipelines continuously assess tradeoffs between computational efficiency, data integrity, and security posture through real-time feedback mechanisms. Our system integrates contextual threat analysis to dynamically modify encryption levels, access controls, and data segregation based on sensitivity classification and detected anomalies. Experimental results demonstrate that systems implementing ADPSSO achieve a 27% improvement in throughput over traditional static pipelines while concurrently reducing security vulnerabilities by 43%. Furthermore, the framework introduces a novel metric for quantifying the business impact of security measures, thereby facilitating evidence-based resource allocation decisions. We validated our methodology with both real-world and simulated datasets across three distinct industrial sectors, demonstrating substantial improvements in both operational efficiency and security robustness. This research establishes a foundation for next-generation data systems capable of autonomously adapting to evolving security landscapes while maintaining optimal performance characteristics.
