> Key: FLINK-28976
> URL: https://issues.apache.org/jira/browse/FLINK-28976
> Project: Flink
> Issue Type: Bug
> Components: Runtime / State Backends
> Affects Versions: 1.15.1, 1.16.0
> Reporter: Roman Khachatryan
> Assignee: Roman Khachatryan
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.16.0, 1.15.3
>
>
> In PeriodicMaterializationManager.start(), the 1st materialization is
> scheduled with a delay: materialization_interval + random_offset
> Here, random_offset is added to avoid thundering herd problem.
> The next materialization will be scheduled with a delay of only
> materialization_interval.
> That means that the 1st materialization will have to compact up to 2 times
> more state changes than the subsequent ones.
> Which in turn can cause FLINK--26590 or other problems.
