DuckDB is great for medium data: Too big for memory, but small enough to fit on local storage. It's also extremely performant for loading data and supports a wide range of storage backends. It's also really well integrated with R and can really speed up certain queries, as long as the DuckDB engine can translate them to valid SQL.
