   > It might be nice to have a higher-level function to read a Parquet file as a stream of batches by the way. 
   
   There are already two options, I think:
   
   - With the parquet module, using `pq.ParquetFile(..).iter_batches()`
   - With the datasets module, using `ds.dataset(...).to_batches()`
   
   The first one should probably be added to that documentation section you linked to, though.
   
   Or are you thinking of even more high level? (something like `pq.read_batches` in addition to `pq.read_table`)
