Hi Group by 和 left join 都是会有 retract 消息的，这类消息需要UpsertStreamTableSink才能处理， Kafka 
connetor 目前的实现是AppendStreamTableSink，所以不能处理 社区已经有一个issue在处理这个问题了，应该1.12能提供这个功能。

版本：1.11.0 问题：flink-sql，数据经过group by 和left join后写入kafka sink，会在语法校验阶段报错： 
AppendStreamTableSink doesn't support consuming update changes which is 
produced by node GroupAggregate

Hi

Group by 和 left join 都是会有 retract 消息的，这类消息需要UpsertStreamTableSink才能处理， Kafka 
connetor 目前的实现是AppendStreamTableSink，所以不能处理
社区已经有一个issue在处理这个问题了，应该1.12能提供这个功能。
