CassandraPartition

case class CassandraPartition(index: Int, endpoints: Iterable[InetAddress], tokenRanges: Iterable[CqlTokenRange], rowCount: Long) extends Partition with Product with Serializable

Metadata describing Cassandra table partition processed by a single Spark task. Beware the term "partition" is overloaded. Here, in the context of Spark, it means an arbitrary collection of rows that can be processed locally on a single Cassandra cluster node. A CassandraPartition typically contains multiple CQL partitions, i.e. rows identified by different values of the CQL partitioning key.

index

identifier of the partition, used internally by Spark

endpoints

which nodes the data partition is located on

tokenRanges

token ranges determining the row set to be fetched

rowCount

estimated total row count in a partition
