Shredding Deeply Nested JSON for Efficient Analytics in DuckDB

Shredding Deeply Nested JSON for Efficient Analytics in DuckDB

Learn how DuckDB efficiently processes and analyzes JSON data in this 21-minute conference talk from the Dutch Seminar on Data Systems Design. Explore the implementation of reading JSON files directly as tables with automatic schema detection, introduced in DuckDB 0.7.0. Discover how semi-structured JSON data, including nested OBJECTs and ARRAYs, is transformed into efficient columnar STRUCT and LIST types for analytical processing. Presented by Laurens Kuiper, a PhD Student at CWI Amsterdam and Software Developer at DuckDB Labs, who specializes in OLAP systems and memory-efficient database performance.
