final class CassandraSession extends AnyRef

Data Access Object for Cassandra. The statements are expressed in Cassandra Query Language (CQL) syntax.

The configured keyspace is automatically created if it doesn't already exists. The keyspace is also set as the current keyspace, i.e. it doesn't have to be qualified in the statements.

All methods are non-blocking.

  26. def prepare(stmt: String): CompletionStage[PreparedStatement]

    Create a PreparedStatement that can be bound and used in executeWrite or select multiple times.

    See Querying tables.

    The configured read consistency level is used.

    You can return this Source as a response in a ServiceCall and the elements will be streamed to the client. Otherwise you have to connect a Sink that consumes the messages from this Source and then run the stream.
