   Metadata describing Cassandra table partition processed by a single Spark task.

2. class CassandraRDDPartitioner[V, T <: Token[V]] extends AnyRef

   Creates CassandraPartitions for given Cassandra table

3. case class CqlTokenRange(cql: String) extends Product with Serializable

   Stores a CQL WHERE predicate matching a range of tokens.

4. class Murmur3PartitionerTokenRangeSplitter extends TokenRangeSplitter[Long, LongToken]

   Fast token range splitter assuming that data are spread out evenly in the whole range.

5. class RandomPartitionerTokenRangeSplitter extends TokenRangeSplitter[BigInt, BigIntToken]

   Fast token range splitter assuming that data are spread out evenly in the whole range.

6. class ServerSideTokenRangeSplitter[V, T <: Token[V]] extends TokenRangeSplitter[V, T] with Logging

   Delegates token range splitting to Cassandra server.

7. class TokenRangeClusterer[V, T <: Token[V]] extends AnyRef

   Divides a set of token ranges into groups containing not more than maxRowCountPerGroup rows and not more than maxGroupSize token ranges.

8. trait TokenRangeSplitter[V, T <: Token[V]] extends AnyRef

   Splits a token range into smaller sub-ranges, each with the desired approximate number of rows.
