Re: 关于flink检查点

一点个人看法: 一般业务场景下,大家都需要对流任务的错误范围有个比较确定性的认知。比如设置固定的5min周期,就可以比较确定流处理即使failover,误差也能控制在五分钟内。 但如果是自适应的间隔,负载越高周期越长,但实际failover在高负载下出现的概率应该远大于低负载,这样的设置实用价值可能就并不太大了。 half coke 于2020年4月15日周三 下午4:15写道: > 是的,根据任务负载的变化自动调整checkpoint的间隔,或者可以通过用户写的逻辑调整检查点。 > 刚开始学习flink,想请教一下。 > > Congxian Qiu 于2020年4月15日周三
