所有已实现的接口:

Serializable, org.apache.flink.table.functions.FunctionDefinition

@Internal
public class RedisRowDataLookupFunction
extends org.apache.flink.table.functions.TableFunction<org.apache.flink.table.data.RowData>

The RedisRowDataLookupFunction is a standard user-defined table function, it can be used in tableAPI and also useful for temporal table join plan in SQL. It looks up the result as RowData.
