> Other physicalexec have the same behavior? I don't know if there is other physical plan has the same behavior. but maybe executing the same partition one more time is not a good idea, it will waste a lot of time, a better way is to cache the result(`OnceFut`), or only call once. `NestedLoopJoinExec` will sometimes build-left, and sometimes build-right now, currently they are using the same logic, the right way is to give `build-left` a logic to handle join, and give `build-right` another logic. The bug of example is the case of `build-right`, I see the `NestedLoopJoinStream` is using `build-left` logic. I think maybe the it is an another cause. @liukun4515 @alamb -- This is an automated message from the Apache Git Service.
