类 OverSpec.GroupSpec

java.lang.Object

org.apache.flink.table.planner.plan.nodes.exec.spec.OverSpec.GroupSpec

封闭类:

OverSpec

public static class OverSpec.GroupSpec
extends Object

OverSpec.GroupSpec describes group of over aggregate calls that have the same window specification.

The specification is defined by an upper and lower bound, and also has zero or more order-by columns.

This class corresponds to Window.Group, but different from Group, the partition spec is defined in OverSpec.
