Summary
DuckDB 1.6.0.dev291 Parquet V2 can produce 256-value DELTA mini-blocks. Velox’s current cuDF pin (5beaa595) fails with DELTA_PARAMS_UNSUPPORTED.
Goal
Pin cuDF to version with (cuDF #23314) fixes this limitation. SF1 V2 smoke tests for Q1/Q3/Q19/Q42/Q52/Q55 successfully read DELTA pages.
Full V2 testing at SF100, SF1000, and SF3000 is still required.
