pitrou opened a new issue, #45722: URL: https://github.com/apache/arrow/issues/45722
### Describe the enhancement requested The following methods are missing from `StructBuilder` and would be useful for high-performance struct array building: * `void UnsafeAppend()` * `void UnsafeAppendNull()` * `void UnsafeAppendNulls(int64_t length)` Ideally the PR should also grep through the source code and convert candidate call sites to the new APIs. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
