Declared as: python:irx:irx.parquet_options.ParquetOptions

Options copied into a native Parquet session at open time.

Empty columns/row_groups select all. Dataset evolution unions same-typed fields only. Atomic replacement and rewrite append are POSIX-local operations with advisory writer exclusion and optional fsync durability. Reconstruct preserves supported logical types over explicit physical storage for single files. Raw AES keys are excluded from repr; callers own key distribution and lifetime.
