Flink Jira Bot updated FLINK-14510:
-----------------------------------
Labels: auto-unassigned stale-major (was: auto-unassigned)
I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Major but is unassigned and neither itself nor its Sub-Tasks have been updated
for 30 days. I have gone ahead and added a "stale-major" to the issue". If this
ticket is a Major, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.
> Remove the lazy vertex attaching mechanism from ExecutionGraph
> --------------------------------------------------------------
>
> Key: FLINK-14510
> URL: https://issues.apache.org/jira/browse/FLINK-14510
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Affects Versions: 1.10.0
> Reporter: Zhu Zhu
> Priority: Major
> Labels: auto-unassigned, stale-major
>
> Currently in production, the vertex attaching is only invoked right after the
> ExecutionGraph is created in ExecutionGraphBuilder. That means lazy attaching
> is not necessary at the moment. It however adds extra complexity to
> ExecutionGraph, since we need to assume that the vertices may be not
> initialized or even get changed.
> Moreover, attaching vertices after a job starts scheduling is an undefined
> behavior which would not work properly.
> I'd propose to remove the lazy attaching mechanism, and do vertices building
> and related components initialization in ExecutionGraph constructor.
