Use multiple statements instead of batches for multi-row operations in CassandraTemplate [DATACASS-289]

[spring-projects-issues]

Mark Paluch opened DATACASS-289 and commented

CassandraTemplate DML operations affecting multiple rows (e.g. insert(List<T> entities)) use Cassandra batches without the possibility of issuing just multiple inserts. Cassandra batches spread over multiple partition keys require the coordinator to manage the work. CassandraTemplate should perform multiple row operations issuing multiple commands as that is the most efficient way due to the distributed nature.

Not going to implement this change. Multi-row operations pretend a functionality that just isn't supported by Cassandra. See See DATACASS-350
