To conclude, we show an example in which multiple units are filled at the same time. The units are processed in the same order as they were requested. In this example, unit 2 has priority over unit 1. Since both units are serialized by the same queue names, there is a sequence dependency. If different queue names were used, then both units could be processed in parallel.
