---------------------------------------
Thanks for the update, Alex.
I get your idea, though a few arrows seem to be missing (e.g. CCF is ?) in the
diagram for toInc.
> Implement FuzzyRowFilter with ranges support

> 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.
