Hi @KienKim ! Impala has a lot of different configuration options, and increasing concurrency is a broad topic to tackle. If you haven't already, I recommend consulting the documentation for the version of CDP you're using. If you get stuck on a particular configuration property, then providing those specifics here would be a good place to start.
