Description
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
