Hi Josh - 

The reason we are trying to do this is that we have two competing
requirements:
1. Maintain an unbounded versioned history of a certain subset or types of
updates (for audit and forensics purposes) for a row
2. Do not add to that row's versioned history for a certain other subset or
types of updates.

So in the same table we want to take advantage of Accumulo's versioning for
some change cases for a record, while for others we would like to avoid new
versions being created because of the very high volume of changes
anticipated.

Thanks.
