zhijiang updated FLINK-5134: ---------------------------- Summary: Aggregate ResourceSpec for chained operators when generating job graph (was: Aggregate ResourceSpe for chained operators when generating job graph) > Aggregate ResourceSpec for chained operators when generating job graph > ---------------------------------------------------------------------- > > Key: FLINK-5134 > URL: https://issues.apache.org/jira/browse/FLINK-5134 > Project: Flink > Issue Type: Sub-task > Components: DataStream API > Reporter: zhijiang > Assignee: zhijiang > > In *JobGraph* generation, each *JobVertex* corresponds to a series of chained > operators. > The resource of *JobVertex* should be aggregation of individual resource in > chained operators. > For memory resource in *JobVertex*, the aggregation is the sum formula for > chained operators. > And for cpu cores resource in *JobVertex*, the aggregation is the maximum > formula for chained operators. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
