Package org.apache.flink.table.runtime.strategy

Class PostProcessAdaptiveJoinStrategy

java.lang.Object

org.apache.flink.table.runtime.strategy.BaseAdaptiveJoinOperatorOptimizationStrategy

org.apache.flink.table.runtime.strategy.PostProcessAdaptiveJoinStrategy

All Implemented Interfaces:

org.apache.flink.runtime.scheduler.adaptivebatch.StreamGraphOptimizationStrategy

public class PostProcessAdaptiveJoinStrategy
extends BaseAdaptiveJoinOperatorOptimizationStrategy

The post-processing phase of adaptive join optimization, which must be placed at the end of all adaptive join optimization strategies. This is necessary because certain operations, like 'reorder inputs', can influence how adaptive broadcast join or skewed join determine the left and right sides.
