Subject Re: [jira] [Commented] (ACCUMULO-227) Improve in memory map counts to provide cell level uniqueness for repeated columns in mutation

I acknowledge everything you say as true - but disagree that the greatest level of flexibility
results in the best experience for the user. BigTable is defined as a map - I think most users
expect a map, and that making Accumulo behave like a multi-map will most likely result in
poorer adoption.
