-----------------------------------

             Summary: [C++] Migrate more computational utility code from 
parquet-cpp
                 Key: ARROW-1154
                 URL: https://issues.apache.org/jira/browse/ARROW-1154
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++
            Reporter: Wes McKinney
            Assignee: Wes McKinney
             Fix For: 0.5.0


There is a bunch of utility code in parquet-cpp that would have a better home 
in arrow/util, and make it easier to implement features down the road such as 
those in ARROW-300. We also need some of these code for computing dictionary 
encoding in Arrow.
