13f7afc49d PT-1757 Fixed NibbleIterator undef 2019-10-14 14:44:57 -03:00
Carlos Salguero
6a302e2b07 PT-1757 Implemented fallback in NibbleIterator 
Since now NibbleIterator can fallback to nibble (from one chunk) pt-osc
can nibble tables even if due to unacurate stats, it choses one nible as
the initial nibbling method.
