Research direction

Start at the C++ binary_join kernel and compare its current list(string) and list(large_string) handling with the related fixed-size-list compute-functions issue. Done means binary_join supports fixed_size_list(string) with string and fixed_size_list(large_string) with large_string, with coverage for both combinations.
