Objectives

This course studies selected internals of DuckDB, a modern database system engineed to efficiently process tabular (or: relational) data. Students will understand how DuckDB represents sizable data volumes on secondary storage (SSDs, say) as well as in RAM in compressed form. The course discusses complex SQL queries and how their plans can be simplified and optimized. To evaluate these plans in parallel, DuckDB maintains pipelines of query operators which process entire vectors of data at a time. The course studies these pipelines as well as the implementation of selected operators like join, sorting, and index-based data access using radix trees. DuckDB maintains data integrity in the face of concurrent access and system outages—students get to know the basic principles that enable the system to keep this promise.
