   > @danielcweeks When we discussed this were you thinking about no metrics for tables with more than 100 columns? or no metrics for anything other than the first 100 columns.

   @RussellSpitzer I would think it would be either all or nothing.  I'm not sure we can speculate that the first 100 columns are somehow more meaningful than those that follow (though I guess you could make that argument).
   
   For now it seems like just taking a simple approach would be better.  There are some edge cases like what happens in the event that someone is incrementally adding columns and it crosses that threshold, but I wouldn't worry about it too much at this point.
