Parquet columnar file format that naturally fits into a table/column data. Since Parquet file itself is indexable, degenerating parquet into an iterable dataset is not desirable as it loses convenience and flexibility. This PR adds tfio.IOTensor.from_parquet support so that it is possible to acess parquet data through natual `__getitem__` operations. Signed-off-by: Yong Tang <[email protected]>
