public abstract class AsyncStateTableStreamOperator<OUT> extends org.apache.flink.runtime.asyncprocessing.operators.AbstractAsyncStateStreamOperator<OUT>
Table operator to invoke close always. This is a base class for both batch and stream operators without key.

This class is nearly identical with TableStreamOperator, but extending from AbstractAsyncStateStreamOperator to integrate with asynchronous state access.
