Type Members

1. case class ClusteredDistribution(clustering: Seq[Expression]) extends Distribution with Product with Serializable

   Represents data where tuples that share the same values for the clustering Expressions will be co-located.

2. sealed trait Distribution extends AnyRef

   Specifies how tuples that share common expressions will be distributed when a query is executed in parallel on many machines.

3. case class HashPartitioning(expressions: Seq[Expression], numPartitions: Int) extends Expression with Partitioning with Product with Serializable

   Represents a partitioning where rows are split up across partitions based on the hash of expressions.

4. case class OrderedDistribution(ordering: Seq[SortOrder]) extends Distribution with Product with Serializable

   Represents data where tuples have been ordered according to the ordering Expressions.

5. sealed trait Partitioning extends AnyRef

6. case class RangePartitioning(ordering: Seq[SortOrder], numPartitions: Int) extends Expression with Partitioning with Product with Serializable

   Represents a partitioning where rows are split across partitions based on some total ordering of the expressions specified in ordering.

7. case class UnknownPartitioning(numPartitions: Int) extends Partitioning with Product with Serializable
