pg_fusion: designing a DataFusion-based query executor inside PostgreSQL, Denis Smirnov, #FOSSASIA

PostgreSQL is renowned for its powerful query engine, but what happens when you combine it with a modern analytics framework like Apache DataFusion? This session introduces pg_fusion, an experimental PostgreSQL extension that embeds DataFusion as an alternative query executor inside PostgreSQL. Learn about the architectural challenges of integrating an asynchronous, multi-threaded execution engine into PostgreSQL's traditional architecture. We'll explore key design decisions, extension development techniques, query execution internals, and the opportunities this approach creates for analytics performance and future database innovation. Whether you're a PostgreSQL contributor, database engineer, systems programmer, or Rust developer, this talk offers a unique look into the future of query processing and database extensibility.
