class BulkTableWriter[T] extends Serializable with Logging

BulkTableWriter writes data directly to sstables in a local directory and then streams sstables to the Cassandra cluster.

    connector

    used to fetch cluster table, as well as to connect to the endpoints to stream data to

    tableDef

    schema of the table to write to, the table must exist in Cassandra

    rowWriter

    extracts individual column values from each RDD item

    outputDirectory

    temporary, writeable directory to dump SSTables into

    deleteSource

    if true, the sstables will be deleted after successful streaming

    bufferSizeInMB

    the larger the buffer, the more memory it takes on the client, but produces bigger sstables, so less compaction on the C* side is needed
