DuckDB vs GenomicsDB

DuckDB: In-process columnar SQL database: the SQLite of analytics, running inside your app or notebook. GenomicsDB: Sparse-array store for genomic variant data, built on TileDB and shipped inside GATK4.

key differences

  • DuckDB is primarily a columnar / OLAP database; GenomicsDB is array / scientific.
  • GenomicsDB is built for larger datasets (≤ 1 PB) than DuckDB (≤ 10 TB).
  • Horizontal scaling is none in DuckDB and manual in GenomicsDB.
  • Transactions: DuckDB offers full ACID; GenomicsDB offers none.
  • Only DuckDB has transactions, joins, secondary indexes, full-text search, vector search.

choose duckdb for

  • +Local data analysis in notebooks
  • +ETL and data-engineering pipelines on files
  • +Embedded analytics inside applications
  • +Querying data lakes on S3 without a cluster

best at · OLAP, Embedded, Lakehouse

choose genomicsdb for

  • +Joint genotyping across large cohorts with GATK
  • +Storing and querying gVCFs for population genomics
  • +Region-based variant queries for research pipelines
