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.
