Hi, I am using this:
x = join a by 1, b by 1 using 'replicated'; with the hope that it generates some synthetic key '1' on both a and b and joins it on that key, thereby, in this case, doing a clean map side cross of a and b with no schema changes (exactly the way a cross would work). It seems to be working, but since I just tried it and it worked, I am not sure if there is anything in there I should be aware of. Does anyone know? Thanks, Mehmet
