Wes McKinney created PARQUET-835:
------------------------------------
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
