> If a multi-part rowkey is defined as "part0:part1:part2", and the where
> clause is like "where part1 = 'xxx' and c1 = 'yyy'", we can take out the
> "part1 = 'xxx'" predicate and make it a FuzzyRowFilter in execution. Thus,
> instead of scanning the entire table, we get the benefit of passing over a
> bunch of rows that should be filtered out.
> The performance gain depends on the proportion of rowkeys that can be
> filtered by FuzzyRowFilter, but is usually very considerable in cases similar
> to the example listed above.
