      Description

      Apart from current ability to specify fuzzy row filter e.g. for <userId_actionId> format as ????_0004 (where 0004 - actionId) it would be great to also have ability to specify the "fuzzy range" , e.g. ????_0004, ..., ????_0099.

      See initial discussion here: http://search-hadoop.com/m/WVLJdX0Z65

      Note: currently it is possible to provide multiple fuzzy row rules to existing FuzzyRowFilter, but in case when the range is big (contains thousands of values) it is not efficient.

      Filter should perform efficient fast-forwarding during the scan (this is what distinguishes it from regex row filter).

      While such functionality may seem like a proper fit for custom filter (i.e. not including into standard filter set) it looks like the filter may be very re-useable. We may judge based on the implementation that will hopefully be added.
