Hey guys, We are designing our data model for our app and this question came up. Lets say that I have a large number of rows(say 1M). And just one column family. Each row contains either columns (A, B, C) or (X, Y, Z). I want to run a get_range_slices query to fetch columns (A, B, C). Does cassandra actually iterate over all 1M rows, and pass me half of them which contain (A, B, C). Or somehow magically it iterates over only half million rows containing (A, B, C). The latter case should run twice as fast as former since it avoids iterating half the data. Thanks in advance!
