Ah I see. Perhaps the need to always have an aggregation confused me, which is specific to relational databases (all? most of? some?). Of course the aggregation has to work on something and that might be the same as a partitioning. Thanks for clearing that up! The downside of a library is often, that it comes with its own dependencies and a lot of things you might not need. In general you should not buy into using a library whenever one is available, that among other things offers one procedure, which you need. The decision to use a library should be thought about a little more.
