Lazily read from a local or cloud-hosted parquet file (or files).
This function allows the query optimizer to push down predicates and projections to
the scan level, typically increasing performance and reducing memory overhead.
This allows the query optimizer to push down predicates and projections to the scan level,
thereby potentially reducing memory overhead.
