Rafferty97 opened a new issue, #11685: URL: https://github.com/apache/datafusion/issues/11685
## Summary Improve the performance of the `struct` and `named_struct` functions by eliminating unnecessary heap allocations. ## Detail In the implementations of the `struct` and `named_struct` functions, the final `StructArray` is created using `StructArray::from` which internally unzips the provided `Vec<(FieldRef, ArrayRef)>>` into two separate vectors. It would therefore be more efficient to simply construct these two separate `Vec`s directly and pass these to `StructArray::new`, avoiding the allocation of the intermediate `Vec<(FieldRef, ArrayRef)>`. -- This is an automated message from the Apache Git Service.
