説明

DuckDB's C API doesn't seems to support filter pushdown, but the C++ one seems to have good support:

https://github.com/duckdb/duckdb/blob/239f51293c429168774c3943e96ddf2451253a07/src/include/duckdb/function/table_function.hpp#L253-L255

It sounds like we can even tell DuckDB which filters we support dynamically.
