Zhijiang Wang updated FLINK-5134:
---------------------------------
Description:
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.
was:In DataStream API, the *ResourceSpec* is setted onto the internal
transformation
> Aggregate ResourceSpe for chained operators when generating job graph
