    Loads the data from DataFrame to a Cassandra table.

    Loads the data from DataFrame to a Cassandra table. Uses the specified column names.

    Writes SSTables to a temporary directory then loads the SSTables directly to Cassandra.

    keyspaceName

    The name of the Keyspace to use.

    tableName

    The name of the Table to use.

    columns

    The list of column names to save data to. Uses only the unique column names, and you must select all primary key columns. All other fields are discarded. Non-selected property/column names are left unchanged.

    sparkCassWriteConf

    Configurations to coordinate and to limit writes.

    sparkCassServerConf

    Configurations to connect to Cassandra Transport Layer.
