> h1. Issues if the design candidate accepted
> After applying the fix（FLINK-33123） based on the current approach, there is
> still an issue with the Web UI when displaying edge types during a rescale.
> Specifically, after a job is rescaled, the page needs to be manually
> refreshed before the correct edge types are shown in a timely manner, as
> illustrated in
> [here|https://docs.google.com/document/d/1e_6o4bdXcKtFL3xYxKeyKnRjR8ffsw6Z8frp3tp7u-M/edit?tab=t.0#heading=h.hxuucagvlvbj]

> h2. The root cause
> The UI used the job graph edges cache and did not use the latest edge name to
> show.
> h2. The Solution
> It is sufficient to remove the caching mechanism for JobGraph edges in the
> corresponding frontend page request logic and instead use the latest
> retrieved edge information(from [http://$|http://$/]
> {host}
> :${port}/jobs/${jobid}).
