Class LogicalDistribution

java.lang.Object
org.apache.calcite.rel.AbstractRelNode
org.apache.calcite.rel.SingleRel
org.apache.flink.table.planner.plan.nodes.hive.LogicalDistribution
All Implemented Interfaces:
Cloneable, org.apache.calcite.plan.RelOptNode, org.apache.calcite.rel.RelNode
public class LogicalDistribution extends org.apache.calcite.rel.SingleRel
LogicalDistribution is used to represent the expected distribution of the data, similar to Hive's SORT BY, DISTRIBUTE BY, and CLUSTER BY semantics.
