hi, cassandra supports hadoop to map & reduce from cassandra.
now I am digging to find out a way to map from a file and cassandra together. I mean if both of them are files in my disk, it is possible by using splits. but, in this kind of a situtation, which way is posssible? for example. in a cassandra) key1| value1 | value2 key2| value3 | value4 key3| value5 | value6 in a file) key1| value1 | value2 key2| value7 | value4 key3| value7 | value6 the size of both are very hugh. I want to get a result from diff from both of them. which keys are deleted? which values are changed? thanks.
