DuckDB vs SQLite

DuckDB: In-process columnar SQL database: the SQLite of analytics, running inside your app or notebook. SQLite: The in-process SQL engine that ships in every phone, browser and OS: one file, zero servers.

key differences

  • DuckDB is primarily a columnar / OLAP database; SQLite is relational.
  • DuckDB is built for larger datasets (≤ 10 TB) than SQLite (≤ 100 GB).
  • Only DuckDB has vector search, geospatial, columnar storage, compression, encryption at rest.
  • Only SQLite has triggers.

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

choose sqlite for

  • +Mobile and desktop application storage
  • +Embedded devices and IoT
  • +Local-first apps and offline caches
  • +Test fixtures and data interchange files
