TileDB-VCF

Overview

TileDB-VCF is a high-performance C++ library with Python and CLI interfaces for efficient storage and retrieval of genomic variant-call data. Built on TileDB's sparse array technology, it enables scalable ingestion of VCF/BCF files, incremental sample addition without expensive merging operations, and efficient parallel queries of variant data stored locally or in the cloud.

When to Use This Skill

This skill should be used when:

• Learning TileDB-VCF concepts and workflows
• Prototyping genomics analyses and pipelines
• Working with small-to-medium datasets (< 1000 samples)
• Need incremental addition of new samples to existing datasets
• Require efficient querying of specific genomic regions across many samples
• Working with cloud-stored variant data (S3, Azure, GCS)
• Need to export subsets of large VCF datasets
• Building variant databases for cohort studies
• Educational projects and method development
• Performance is critical for variant data operations
