The Cassandra EntityStore can either use an existing Cassandra Keyspace, which is the default, OR create its own keyspace.
The {@code CassandraEntityStoreConfiguration#keyspaceName()} defines the name of the keyspace to use, or to be created. If not defined, then the default name is "polygene".
The {@code CassandraEntityStoreConfiguration#createIfMissing()} defines if new missing resources should be created or an Exception should be thrown if missing.
If it is created, then the {@code CassandraEntityStoreConfiguration#replicationFactor()} will define the replication factor, and the command to create the keyspace is;
CREATE KEYSPACE <keyspaceName> WITH replication = {'class':'SimpleStrategy', 'replication_factor' : <replicationFactor> };
Polygene will store all entities in a single Cassandra TABLE
CREATE TABLE <tableName> (
