Subject Tracking cardinality in Accumulo
Date Fri, 16 May 2014 17:54:46 GMT
If I have the following simple set of data:

NAME John
NAME Jake
NAME John
NAME Mary

I want to end up with the following:

NAME 3

I'm thinking that perhaps a HyperLogLog approach should work. See
http://en.wikipedia.org/wiki/HyperLogLog for more information.

Has anyone done this before in Accumulo?
