DuckDB: The SQLite for Analytics
DuckDB is the perfect solution for data analysis and analytics databases like SQLite. Learn how to install and use it for different tasks.
Modern data science combines high-speed in-process analytical engines (DuckDB, Polars) with high-dimensional vector embeddings (HNSW) to power semantic search, recommendation systems, and predictive modeling.

Learn how to use DuckDB for AI applications. Build vector search, ML feature engineering, and RAG pipelines with DuckDB and the vss extension.
An architecture integrating DuckDB with Postgres for vector databasing is presented using the brand new DuckDB Array type and related vector functions.
Data Science and Machine Learning: DuckDB integrates seamlessly with Python and R, making it an excellent choice for data scientists who need to preprocess large datasets, join multiple tables, and perform exploratory data analysis (EDA) within their notebooks or scripts.
Another integration: data science teams could use DuckDB files to share processed data. Instead of CSVs, they send a .duckdb file. The receiver can do duckdb.connect('file.duckdb') and immediately query the data, possibly benefitting from the precomputed stats or indexes.
Data Intensive Applications.import duckdb as db import pandas as pd.
Yes, basic machine learning algorithms can be implemented directly in SQL. DuckDB already supports linear regression as an aggregate function, and k-means clustering can be implemented as a mini-batch version within the database engine.
