Large amounts of writes can make other tests flake. This can happen for reasons such as
overloading the test Cassandra container or knock-on effects of tombstones left from {@link
CassandraContainer#clear(CassandraStorage)}.

<p>Tests here share a different Cassandra container and each method runs in an isolated
keyspace. As schema installation takes ~10s, hesitate adding too many tests here.
