Yangze Guo commented on FLINK-24951:
------------------------------------
Fabric8 5.5.0 can enable this feature, but it cannot handle BOOKMARK events
until 5.9.0[1]. So, we may need to upgrade k8s client as well.
Would bookmark introduce any regression for users? If so, +1 for not enabling
it by default.

> Key: FLINK-24951
> URL: https://issues.apache.org/jira/browse/FLINK-24951
> Project: Flink
> Issue Type: Improvement
> Components: Deployment / Kubernetes
> Affects Versions: 1.15.0
> Reporter: Yangze Guo
> Priority: Major
> Fix For: 1.15.0
>
>
> In some production environments, there are massive pods that create and
> delete. Thus the global resource version is updated very quickly and may
> cause frequent watcher rebuilding because of "too old resource version". To
> avoid this, K8s provide a Bookmark mechanism[1].
> I propose to enable bookmark by default
