C++ Decimal type has such check, e.g. Decimal128Type: https://github.com/apache/arrow/blob/6cc37cf2d1ba72c46b64fbc7ac499bd0d7296d20/cpp/src/arrow/type.cc#L870-L874 But I am not sure if we need to have the check. For unsafe paths, we run value validation which includes such check. For safe paths, I think it assumes the inputs are all valid (including decimal type). You can mess the array with either wrong type or input in safe paths. It appears to me that's a bit verbose when constructing a decimal type with a struct or matching a decimal type. So I personally feel that it has a little advantage but also has some more disadvantage. I don't feel strong against it, though. -- This is an automated message from the Apache Git Service.
