Re: streaming.api.operators和streaming.runtime.operators的区别是啥?

2023-05-06 Thread Hongshun Wang
我来谈一下我个人的看法,streaming.api.operators是提供给用户使用的stream api,
用户可以使用和扩展该接口。而streaming.runtime.operators是用户侧不感知,在执行时由flink自动调用的。比如:
Sink用户可以自己设置,如kafkaSink。但是输出时的state处理和事务commit(CommitterOperator)是Flink根据不同类型的Sink自动生成的统一逻辑,用户无需自己设置和实现。

Re: 使用Flink SQL如何实现支付对帐超时告警?

2023-05-10 Thread Hongshun Wang
Hi  casel.chen,
我理解你的意思是:
希望在ThirdPartyPaymentStream一条数据达到的30分钟后,*再触发查询*
,如果此时该数据在PlatformPaymentStream中还未出现,说明超时未支付,则输入到下游。而不是等ThirdPartyPaymentStream数据达到时再判断是否超时,因为此时虽然超时达到,但是也算已支付,没必要再触发报警了。

如果是流计算,可以采用timer定时器延时触发。

对于sql, 我个人的一个比较绕的想法是(供参考,不一定对):是通过Pulsar
Sink(或RocketMQ等有延迟队列的消息中间件)将PlatformPaymentStream的数据写入延迟队列(30分钟)[1],
然后延迟消费为PlatformPaymentStream2。然后将PlatformPaymentStream2 *left join*
ThirdPartyPaymentStream, 如果join后的结果不包含ThirdPartyPaymentStream部分,说明没有及时付款。

Re: Re:RE: RE: flink cdc动态加表不生效

2024-03-07 Thread Hongshun Wang
Hi, casel chan,
社区已经对增量框架实现动态加表(https://github.com/apache/flink-cdc/pull/3024
),预计3.1对mongodb和postgres暴露出来,但是Oracle和Sqlserver目前并没暴露,你可以去社区参照这两个框架,将参数打开,并且测试和适配。
Best,
