Date Thu, 17 Mar 2016 11:28:33 GMT

    [ https://issues.apache.org/jira/browse/FLINK-3492?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15199342#comment-15199342

ASF GitHub Bot commented on FLINK-3492:

Github user zentol commented on the pull request:

    Third time's the charm:
    * the time of the last triggered checkpoint is stored
    * when a checkpoint is triggered we check whether the interval has passed, if so we reschedule
the next checkpoint with a delay of minInterval
    * test added

> FLINK-3051 introduced already a filed in the {{CheckpointConfig}} to specify a min pause
between checkpoints.
> In high-load situations (big state), jobs might spend their entire time creating snapshots,
not processing data. With a min pause between checkpoints, users can guarantee that there
is a certain time-span the system can use for doing some actual data processing.
