The need for auto schema evolution in modern data engineering: Challenges and solutions

Sekar, Rajkumar (2025) The need for auto schema evolution in modern data engineering: Challenges and solutions. World Journal of Advanced Research and Reviews, 26 (1). pp. 909-917. ISSN 2581-9615

The document explores auto schema evolution in modern data engineering, addressing the challenges organizations face when managing schema changes across complex data ecosystems. It examines how traditional manual approaches to schema migration create significant operational inefficiencies, system downtime, and technical debt. The text describes advanced schema evolution technologies including schema-aware storage formats, centralized registries, and compatibility policies that enable dynamic adaptation of data structures with minimal human intervention. Various implementations across stream processing systems, cloud data warehouses, and data lakes demonstrate substantial improvements in system reliability, developer productivity, and business agility. The document also discusses challenges related to data quality validation, performance impacts, and governance considerations that organizations must address when implementing automated schema evolution approaches.
