Description

This episode explores DuckLake, an open table format that stores metadata in a SQL database and data in plain Parquet files. Unlike other formats that require multiple file reads before accessing data, DuckLake asks a single SQL query to identify relevant files. Pedro discusses his work as the lead DuckLake developer, while Guillermo explains how DuckLake handles hundreds of transactions per second using the Quack protocol, far exceeding other open table formats.
