Genomic Variant Frequency Analysis with Performance Optimization

genomics performance indexing large-scale data
Prompt
Design a PostgreSQL database schema and query mechanism to efficiently analyze large-scale genomic variant frequencies across multiple research datasets. Create an indexing strategy that can handle over 10 million genetic variant records while maintaining sub-second query performance. Implement a partitioning approach that allows rapid filtering by chromosome, mutation type, and population cohort. Include specific recommendations for handling complex JSON-encoded genetic metadata and ensuring referential integrity.
