It is possible to massively distribute joins but it requires a much more sophisticated database design than you see in most distributed database implementations because the whole system has to be designed for that use case e.g. support for ad hoc inter-node orchestration and data flows. At that point you basically have a parallel database instead of just a distributed one.

And if you add an additional requirement to correctly execute ad hoc consistent joins under very high write workloads and continuous failures, then it is definitely non-trivial engineering. But it is possible, I've designed implementations like this before, it just requires a very high degree of effort and skill that is rarely applied to the design of typical NoSQL databases.
