## Which issue does this PR close? Closes #8355 ## Rationale for this change Explained in the issue. Please note that I've previously tried to do this using `MemoryExec` in #8412, but since `MemoryExec` doesn't have a serializer and it wasn't trivial to implement one, I took the original way proposed in the issue. ## What changes are included in this PR? In this PR I'm splitting `EmptyExec` case of `produce_one_row=true` to `PlaceHolderRowExec`. What I didn't do here is that I didn't split the same case in `EmptyRelation`, probably better to do it in a separate PR. ## Are these changes tested? Yes. the tests can be find the `PlaceHolderRowExec` file. Also the integration tests are changed to reflect this change. ## Are there any user-facing changes? When showing the physical plan, instead of `EmptyExec produce_one_row=value` there are now two different cases: `EmptyExec` and `PlaceHolderRowExec` -- This is an automated message from the Apache Git Service.
