Deserializes first n columns from the given Row
and returns them as
a CassandraRow
object.
Deserializes first n columns from the given Row
and returns them as
a CassandraRow
object. The number of columns retrieved is determined by the length
of the columnNames argument. The columnNames argument is used as metadata for
the newly created CassandraRow
, but it is not used to fetch data from
the input Row
in order to improve performance. Fetching column values by name is much
slower than fetching by index.
Creates a CassandraRow object from a map with keys denoting column names and values denoting column values.
