Review Comment:
Few clarification questions to ensure we are on the same page.
1. Will this source assume partitioning based on directory structure or user
can choose partition columns from the parquet file schema ?
2. If a parquet file is removed from the source root path, will it be
handled or ignored ? Using file notifications makes this easier but we can find
a way to do this through listing as well.
