Matt McCline updated HIVE-17147:
--------------------------------
Description:
Current limitations:
Only a one long key test currently. Need more tests.
The hive-jmh test doesn't handle multiple iterations. And, the number of rows
and keys being driven through is way too small to be meaningful.
The focus of this change was to get things started.
