类 ResultRetryStrategy

java.lang.Object

org.apache.flink.table.runtime.operators.join.lookup.ResultRetryStrategy

所有已实现的接口:

Serializable, org.apache.flink.streaming.api.functions.async.AsyncRetryStrategy<org.apache.flink.table.data.RowData>

public class ResultRetryStrategy
extends Object
implements org.apache.flink.streaming.api.functions.async.AsyncRetryStrategy<org.apache.flink.table.data.RowData>

A utility class to wrap the data stream api AsyncRetryStrategy to support both sync and async retry in table module. The main consideration is making the class name not bind to async scope, and also highlight the retry predicate is only over the result (not exception).
