-------------------------------------
Assignee: (was: Xu Pingyong)
> Memory consumer weights should be calculated in job vertex level
> ----------------------------------------------------------------
>
> Key: FLINK-6309
> URL: https://issues.apache.org/jira/browse/FLINK-6309
> Project: Flink
> Issue Type: Improvement
> Components: API / DataSet
> Reporter: Kurt Young
> Priority: Major
> Labels: auto-unassigned
>
> Currently, in {{PlanFinalizer}}, we travel all the job vertices to calculate
> the consumer weights of the memory and then assign the weights for each job
> vertex. In the case of a large job graph, e.g. with multiple joins, group
> reduces, the value of consumer weights will be very high and the available
> memory for each job vertex will be very low.
> I think it makes more sense to calculate the consumer weights of the memory
> at the job vertex level (after chaining), in order to maximize the usage
> ratio of the memory.
