Description

*Note*: migrated from original JIRA: https://issues.apache.org/jira/browse/ARROW-6712

What's the best way to read a .parquet file into a rust ndarray structure?

Can it be effective with the current API? I assume row iteration is not the best idea :) 

I can imagine that even parallel column loading would be possible.
