Note: this is not related to the Cassandra cluster name (though you are free to provide
the same name). See Cluster.getClusterName()
for details.
If you use this method and create more than one Cluster instance in the same JVM (which should be avoided unless you need to connect to multiple Cassandra clusters), you should make sure each Cluster instance get a unique name or you may have a problem with JMX reporting.

Cluster.Builder
The driver supports versions 1 to 5 of the native protocol. Higher versions of the protocol have more features and should be preferred, but this also depends on the Cassandra version:
Protocol version | Minimum Cassandra version |
---|---|
1 | 1.2 |
2 | 2.0 |
3 | 2.1 |
4 | 2.2 |
5 | 3.10 |
By default, the driver will "auto-detect" which protocol version it can use when
connecting to the first node. More precisely, it will try first with ProtocolVersion.NEWEST_SUPPORTED
, and if not supported fallback to the highest version
supported by the first node it connects to. Please note that once the version is
"auto-detected", it won't change: if the first node the driver connects to is a Cassandra 1.2
node and auto-detection is used (the default), then the native protocol version 1 will be use
for the lifetime of the Cluster instance.
By using Cluster.Builder.allowBetaProtocolVersion()
, it is possible to force driver to
connect to Cassandra node that supports the latest protocol beta version. Leaving this flag
out will let client to connect with latest released version.
This method allows to force the use of a particular protocol version. Forcing version 1 is
always fine since all Cassandra version (at least all those supporting the native protocol in
the first place) so far support it. However, please note that a number of features of the
driver won't be available if that version of the protocol is in use, including result set
paging, BatchStatement
, executing a non-prepared query with binary values (Session.execute(String, Object...)
), ... (those methods will throw an
UnsupportedFeatureException). Using the protocol version 1 should thus only be considered
when using Cassandra 1.2, until nodes have been upgraded to Cassandra 2.0.
If version 2 of the protocol is used, then Cassandra 1.2 nodes will be ignored (the driver won't connect to them).
The default behavior (auto-detection) is fine in almost all case, but you may want to force a particular version if you have a Cassandra cluster with mixed 1.2/2.0 nodes (i.e. during a Cassandra upgrade).
withProtocolVersion
in class Cluster.Builder
version
- the native protocol version to use. null
is also supported to trigger
auto-detection (see above) but this is the default (so you don't have to call this method
for that behavior).public DseCluster.Builder addContactPoint(String address)
Cluster.Builder
InetAddress
s (A records).
Contact points are addresses of Cassandra nodes that the driver uses to discover the cluster topology. Only one contact point is required (the driver will retrieve the address of the other nodes automatically), but it is usually a good idea to provide more than one contact point, because if that single contact point is unavailable, the driver cannot initialize itself correctly.
Note that by default (that is, unless you use the Cluster.Builder.withLoadBalancingPolicy(com.datastax.driver.core.policies.LoadBalancingPolicy)
) method
of this builder), the first successfully contacted host will be used to define the local
data-center for the client. If follows that if you are running Cassandra in a multiple
data-center setting, it is a good idea to only provide contact points that are in the same
datacenter than the client, or to provide manually the load balancing policy that suits your
need.
If the host name points to a DNS record with multiple a-records, all InetAddresses
returned will be used. Make sure that all resulting InetAddress
s returned point
to the same cluster and datacenter.

Note that all contact points must be resolvable; if any of them cannot be resolved, this method will fail.

public DseCluster.Builder addContactPointsWithPorts(Collection<InetSocketAddress> addresses)
Cluster.Builder
See Cluster.Builder.addContactPoint(java.lang.String)
for more details on contact points. Contrarily to
other addContactPoints
methods, this method allows to provide a different port for
each contact point. Since Cassandra nodes must always all listen on the same port, this is
rarely what you want and most users should prefer other addContactPoints
methods to
this one. However, this can be useful if the Cassandra nodes are behind a router and are not
accessed directly. Note that if you are in this situation (Cassandra nodes are behind a
router, not directly accessible), you almost surely want to provide a specific AddressTranslator
(through Cluster.Builder.withAddressTranslator(com.datastax.driver.core.policies.AddressTranslator)
) to translate actual Cassandra
node addresses to the addresses the driver should use, otherwise the driver will not be able
to auto-detect new nodes (and will generally not function optimally).

public DseCluster.Builder withLoadBalancingPolicy(LoadBalancingPolicy policy)
If you use graph analytics queries, it should be wrapped into a DseLoadBalancingPolicy
to ensure that queries are routed optimally.
If no load balancing policy is set through this method, the default is to use a Policies.defaultLoadBalancingPolicy()
wrapped into a TargetingLoadBalancingPolicy
.

for more detail on address translation, but the default
translator, IdentityTranslator
, should be correct in most cases. If unsure, stick to
the default.

- the translator to use.public DseCluster.Builder withTimestampGenerator(TimestampGenerator timestampGenerator)
Cluster.Builder
This feature is only available with version V3
or above of the
native protocol. With earlier versions, timestamps are always generated server-side, and
setting a generator through this method will have no effect.
If no generator is set through this method, the driver will default to client-side
timestamps by using AtomicMonotonicTimestampGenerator
.

Cluster.Builder
CodecRegistry
instance to use for the new cluster.
If no codec registry is set through this method, CodecRegistry.DEFAULT_INSTANCE
will be used instead.
Note that if two or more Cluster
instances are configured to use the default codec
registry, they are going to share the same instance. In this case, care should be taken when
registering new codecs on it as any codec registered by one cluster would be immediately
available to others sharing the same default instance.

This should be used if the Cassandra cluster has been configured to use the PasswordAuthenticator
. If the the default AllowAllAuthenticator
is used instead,
using this method has no effect.

Use this method when a custom authentication scheme is in place. You shouldn't call both
this method and withCredentials

instance as one will
supersede the other

.
Calling this method will use the JDK-based implementation with the default options (see
RemoteEndpointAwareJdkSSLOptions.Builder
). This is thus a shortcut for withSSL(JdkSSLOptions.builder().build())
.
Note that if SSL is enabled, the driver will not connect to any Cassandra nodes that doesn't have SSL enabled and it is strongly advised to enable SSL on every Cassandra node if you plan on using SSL in the driver.

) but can be disabled using this
option. If metrics are disabled, this is a no-op.
