Subject Re: Group by ColumnFamily?
Date Fri, 18 May 2012 12:58:32 GMT
As I reread my message, I feel that I did not provide enough background.

I am using the SummingCombiner to sum metrics. This step provides
essentially facet counts about my data:

ROWID ACTION RUNNING 5
ROWID ACTION WALKING 33
ROWID ACTION DRINKING 45

This works great. My next concern is to count the number of unique actions.
