    Save this SCollection as a Cassandra table.

    Save this SCollection as a Cassandra table.

    Cassandra org.apache.cassandra.hadoop.cql3.CqlBulkRecordWriter is used to perform bulk writes for better throughput. The SCollection is grouped by the table partition key before written to the cluster. Therefore writes only occur at the end of each window in streaming mode. The bulk writer writes to all nodes in a cluster so remote nodes in a multi-datacenter cluster may become a bottleneck.
