Examples of CqlRow

org.apache.cassandra.thrift.CqlRow
Row returned from a CQL query. This struct is used for both CQL2 and CQL3 queries. For CQL2, the partition key is special-cased and is always returned. For CQL3, it is not special cased; it will be included in the columns list if it was included in the SELECT and the key field is always null.
