I was trying to develop a pipeline where it compares the data of two systems . I have collected huge data from those two systems and I need to find the mismatch of data . I thought of splitting this work in two ways . First to find the mismatch of data under the same header and this is easy by using joins and the other is there are some headers present in system 1 which are not in system 2 and vice versa . So it could be useful if we have any header comparison technique handled by Snap or atleast anything like which displays the count of headers or rows ?
