According to https://issues.apache.org/jira/browse/CASSANDRA-7304 unset
values in a prepared statement for a counter does not change the value of
the counter. This applies for versions of Cassandra 2.2 and above.
I would also look to verify the claimed behaviour myself.

I just have a bunch of counters in 1 row, and I want to selectively update
them. And I want to keep prepared queries. But I don't want to keep 30
prepared queries (1 for each counter column, but keep only 1). So in most
cases, I will increment 1 column by positive integer and the others by 0.
