Review Comment:
Parquet now accepts `format_options` too. I used `connector_options` for
advanced sink options to keep the naming consistent across readers and writers.
Defaults are applied after user options, so `format_options={"compression":
"GZIP"}` is preserved rather than overwritten by the SNAPPY default.
