> Several of the nexmark queries can be improved to have better performance:
> - Query3 uses stateful processing and a CogroupByKey which introduces an
> unnecessary shuffle compared to just using stateful processing. Additionally
> BagState is more appropriate to use than ValueState<List<>>
> - Query5 uses a binary combiner when a custom combiner is more appropriate
> - Query10 has excessive logging
