  1. def createCassandraTable(keyspaceName: String, tableName: String, partitionKeyColumns: Option[Seq[String]] = None, clusteringKeyColumns: Option[Seq[String]] = None)(implicit connector: CassandraConnector = CassandraConnector(sparkContext)): Unit

    Creates a C* table based on the Dataset Struct provided.

    Creates a C* table based on the Dataset Struct provided. Optionally takes in a list of partition columns or clustering columns names. When absent the first column will be used as the partition key and there will be no clustering keys.
