    • Last night I watched Join Order Optimization with (almost) no Statistics by Tom Ebergen. In this video, Tom describes enhancements he made to the join planner in DuckDB, and how it applies both to native tables where you have some extra metadata about the contents of each column, and on external files such as Parquet or CSV, where you don't know much about the actual contents. Good watching if you have any interest in database systems.
