Why Phantom-DSL have ContactPoints and ContactPoint two different ways for Connectors?
While using ContactPoint I can omit using host or can have host as String but I have to declare port in here.
val default: CassandraConnection = ContactPoint(port).keySpace(keyspace)
But while using ContactPoints for connection I have to declare host as Seq[String] and can have or omit port here.
val default: CassandraConnection = ContactPoints(host).keySpace(keyspace)
Is there any other difference than what I am thinking?
The usage really depends on the underlying Cassandra cluster. If you have let's say a single instance of Cassandra then
ContactPoint
will suffice. However, a more realistic case is when you have a 3-Node Cassandra cluster in which case you might want to declare the contact points for every single instance separately throughContactPoints
