             Summary: [C++] Add option to parquet::arrow to read columns in parallel using a thread pool
                 Key: PARQUET-835
                 URL: https://issues.apache.org/jira/browse/PARQUET-835
             Project: Parquet
          Issue Type: New Feature
          Components: parquet-cpp
            Reporter: Wes McKinney


For Parquet file reading that is not IO-bound, we can go faster by reading columns in multiple threads (assuming underlying the IO source is threadsafe). The code will be very similar to that in https://github.com/apache/arrow/blob/master/python/src/pyarrow/adapters/pandas.cc#L1193
