**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** This is a follow-up of #1720. We have added `concatenate by elements` support for string array and put it into the new created `string` kernel. I suggest we should rename the kernel `concatenate_elements`. There are some reasons I thought why `concatenate_elements` is better than `string`: 1. The name of the compute kernel should express what kind of operation will be done on an array, such as `cast`, `aggregate` ... 2. We can support the `concatenate_elements` operation on binary array, list array and other nested types. So `string` is not an appropriate name. 3. In cudf (which is based on Arrow c++, and more GPU supported), there are similar kernels and we can refer to their names.: https://github.com/rapidsai/cudf/blob/branch-22.08/cpp/src/lists/combine/concatenate_list_elements.cu https://github.com/rapidsai/cudf/blob/branch-22.08/cpp/src/lists/combine/concatenate_rows.cu **Describe the solution you'd like** A clear and concise description of what you want to happen. **Describe alternatives you've considered** A clear and concise description of any alternative solutions or features you've considered. **Additional context** Add any other context or screenshots about the feature request here. -- This is an automated message from the Apache Git Service.
