WillAyd opened a new issue, #44956: URL: https://github.com/apache/arrow/issues/44956
### Describe the enhancement requested While investigating https://github.com/apache/arrow/issues/44336 I believe I ran into the limitation that the compute modules pass along an `ExecSpan` object which contains a collection of `ArraySpan` objects. AFAICT, the `ArraySpan` is hard-coded to assume 3 fixed buffers, making it difficult to implement compute for variadic types: https://github.com/apache/arrow/blob/8ac434fb97ab5fb0adc7591736826b2d1db76b9d/cpp/src/arrow/array/data.h#L441 I assume that the `ArraySpan` therefore needs to be updated to support more than 3 buffers, although if I am going down the wrong path with this happy to be corrected ### Component(s) C++ -- This is an automated message from the Apache Git Service.
