DuckDB is a SQL OLAP database management system.
Data scientists and data engineers
DuckDB was designed with both data science and data engineering workloads in mind.
Interactive data analysis (data science), automated data processing pipelines (data engine
DuckDB's use cases can be split into roughly three major categories. Namely, DuckDB can be used for interactive data analysis by a user ("data science") and as pipeline component for automated data processing ("data engineering"). DuckDB can also be deployed in novel architectures, where one traditionally couldn't run an analytical database management system but DuckDB is available thanks to its portability. These ar

DuckDB is a single-node database system, hence it makes use of vertical scalability, i.e., making use of more resources (CPU, memory, and disk) to support larger datasets. DuckDB has been tested on machines with 100+ CPU cores and terabytes of memory.
