Incremental Schema Fingerprinting with MinHash for Drift Detection in Data Lakes

Abstract

The work incrementally fingerprints MinHash schema. Finding schema drift in huge data lakes is quicker and easier with this strategy. This method creates small hashes of changing table schema column names, data types, and semantic tags. Weekly lightweight comparisons may show quality or compliance issues. Structured monitoring employing semantic fingerprinting may uncover minor schema semantic changes that mask origin or governance. Open-source datasets and real-world intake evaluate system accuracy, recall, and computation runtime. To assist data stewards examine schemas, metadata catalogue systems identify and display schema drift. Experimental findings show reliable, space-efficient detection for near-real-time governance enforcement in petabyte data lakes. Compliance-aware observability and scalable summarisation improve schema monitoring.
