Hello all, I've noticed that when performing a SELECT statement with a list of columns specified, Cassandra returns all columns in the resulting row(s) even if they have no value. This creates an apparently considerable amount of transport and deserialization overhead, particularly in one use case I'm looking at, in which we select a large collection of columns but expect only a small fraction of them to contain values. Is there any way to get around this and only receive columns that have values in the results?
Thanks, Mat
