      Description

      Some systems, such as HBase, have a named group to which columns belong (i.e. a column family in this case). To disambiguate column references (i.e. if the same column name is used in different column families), it's useful to allow an optional qualifier. This is similar to the RECORD field mechanism that Calcite already supports, but in this case the record name would be optional, since it's not necessary if the column names are unique. For example: http://phoenix.apache.org/language/index.html#column_ref
