      Description

      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.
