> This is a part of fine-grained resource configuration in flip-6.
> In *JobGraph* generation, each *JobVertex* may contain a series of chained operators, and 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, the aggregation is the maximum formula for chained operators.
