Manages high-performance storage and retrieval of genomic variant data using TileDB's sparse array technology.
This skill provides specialized guidance for using TileDB-VCF, a C++ library with Python interfaces designed for scalable population genomics. It helps users manage large-scale VCF/BCF datasets by enabling incremental sample ingestion without costly merge operations, facilitating efficient parallel queries across genomic regions, and integrating seamlessly with cloud storage providers like AWS, Azure, and GCP. Whether prototyping local pipelines or building production-grade variant databases, this skill ensures best practices for memory management, coordinate systems, and data export for downstream bioinformatics analysis.
