the
documentation
- partition and distribution default to left-to-right attribute order (backward compat preserved) - partition_rank and distribution_rank override that independently - rank values must be unique within their respective set - add example showing decoupled partition vs distribution ordering
…ple names - Restore 'partitioning key functions as GROUP BY column' sentence - Correct rank constraint: consecutive sequence starting from 1, not just unique - Update example to use Date Dimension/Year/Month consistent with file conventions
