•  package connector

  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()

  Contains a cql.CassandraConnector object which is used to connect to a Cassandra cluster and to send CQL statements to it.

  Contains a cql.CassandraConnector object which is used to connect to a Cassandra cluster and to send CQL statements to it. CassandraConnector provides a Scala-idiomatic way of working with Session object and takes care of connection pooling and proper resource disposal.
