                 URL: https://issues.apache.org/jira/browse/ARROW-1844

             Fix For: 0.8.0


* Integers, small cardinality and large cardinality
* Short strings, small/large cardinality
* Long strings, small/large cardinality

These benchmarks will enable us to refactor without fear, and to experiment 
with faster hash functions
