Suppose you have the following graph related situation:
A customer is working on creating aggregates for their virtual meters. These virtual meters can connect to physical meters or other virtual meters. They are looking at looping to aggregate each level, but it seemed to me more like a graph problem. Is there an easy way to sum readings from physical's and keep that aggregate going through each vertices. We would only know the physical readings to start. The attached image is what I was thinking could happen by filling out the aggregates at it virtual.
This notebook provides an example of how to implement the desired aggregation using the message passing API in GraphFrames on Apache Spark.
