I have encountered the same problem. I think this problem is caused by the shortcut in if_else kernel when left is invalid. https://github.com/apache/arrow/blob/apache-arrow-17.0.0/cpp/src/arrow/compute/kernels/scalar_if_else.cc#L740-L750 This shortcut is not safe when right is a chunk of other larger array. In this case, offset of right might starts from the middle of larger array. Because this shortcut copies value of right to value of output, offset of output should start from zero, but just a copy of right is used. -- This is an automated message from the Apache Git Service.
