Hi Shuwen,
As far as I know, Flink can only support checkpoint with a fixed interval. However I think the flexible mechanism of triggering checkpoint is worth working on, at least from my perspective. And it may not only be a cron style. In our business scenario, the data traffic usually reaches the peek of the day after 20:00, which we want to increase the interval of checkpoint otherwise it’ll introduce more disk and network IO. Just want to share something about this :) Best, Jiayi Liao At 2019-11-21 10:20:47, "shuwen zhou" <jaco...@gmail.com> wrote: >Hi Community, >I would like to know if there is a existing function to support cron style >checkpoint? >The case is, our data traffic is huge on HH:30 for each hour.
