Class HiveExecutableOperation

java.lang.Object

org.apache.flink.table.planner.delegation.hive.operations.HiveExecutableOperation

All Implemented Interfaces:

ExecutableOperation, Operation

public class HiveExecutableOperation
extends Object
implements ExecutableOperation

An ExecutableOperation for Hive dialect. It'll wrap the actual Operation, and delegate the execution logic of the wrapped operation to HiveOperationExecutor.

Todo: It's just a temporary way just for simplify, should refactor it to make each of the extra Operations customized for Hive execute it's own logic in it's own inner `execute` method in FLINK-31607
