    The root package of Cassandra connector for Apache Spark.

    The root package of Cassandra connector for Apache Spark. Offers handy implicit conversions that add Cassandra-specific methods to SparkContext and RDD.

    Call cassandraTable method on the SparkContext object to create a CassandraRDD exposing Cassandra tables as Spark RDDs.

    Call RDDFunctions saveToCassandra function on any RDD to save distributed collection to a Cassandra table.

    Example:

    CREATE KEYSPACE test WITH replication = {'class': 'SimpleStrategy', 'replication_factor': 1 };
    CREATE TABLE test.words (word text PRIMARY KEY, count int);
    INSERT INTO test.words(word, count) VALUES ("and", 50);
    import com.datastax.spark.connector._
    
    val sparkMasterHost = "127.0.0.1"
    val cassandraHost = "127.0.0.1"
    val keyspace = "test"
    val table = "words"
    
    // Tell Spark the address of one Cassandra node:
    val conf = new SparkConf(true).set("spark.cassandra.connection.host", cassandraHost)
    
    // Connect to the Spark cluster:
    val sc = new SparkContext("spark://" + sparkMasterHost + ":7077", "example", conf)
    
    // Read the table and print its contents:
    val rdd = sc.cassandraTable(keyspace, table)
    rdd.toArray().foreach(println)
    
    // Write two rows to the table:
    val col = sc.parallelize(Seq(("of", 1200), ("the", "863")))
    col.saveToCassandra(keyspace, table)
    
    sc.stop()
