Completely missed out on QualifierFilter. Thanks Alok. Since QualifierFilter is going to use regex. I would say that QualifierFilter wont be super efficient. At present, i want to do this quickly. In near future, if time permits, i will try to write ColumnSuffixFilter and use it. An observation regarding naming, "ColumnPrefixFilter" and "QualifierFilter" names are not coherent. IMHO, we should either call ColumnQualifier as "Column" or "Qualifier". Using both interchangeably creates confusion.
