A cluster object describes the configuration of the Cassandra cluster and is used to construct a session instance. Unlike other DataStax drivers the cluster object does not maintain the control connection.
Public Functions
Creates a new cluster.

Returns a cluster that must be freed.
Frees a cluster instance.
cluster – [in]
Sets/Appends contact points. This MUST be set. The first call sets the contact points and any subsequent calls appends additional contact points. Passing an empty string will clear the contact points. White space is striped from the contact points.
Examples: “127.0.0.1” “127.0.0.1,127.0.0.2”, “server1.domain.com”
cluster – [in]
contact_points – [in] A comma delimited list of addresses or names. An empty string will clear the contact points. The string is copied into the cluster configuration; the memory pointed to by this parameter can be freed after this call.
CASS_OK if successful, otherwise an error occurred.

Sets the range of outgoing port numbers (ephemeral ports) to be used when establishing the shard-aware connections. This is applicable when the routing of connection to shard is based on the client-side port number.
When application connects to multiple CassCluster-s it is advised to assign mutually non-overlapping port intervals to each. It is assumed that the supplied range is allowed by the OS (e.g. it fits inside /proc/sys/net/ipv4/ip_local_port_range on *nix systems)

Default: cass_false

wait_time – [in]
Configures the cluster to use a reconnection policy that waits a constant time between each reconnection attempt.
cluster – [in]
delay_ms – [in] Time in milliseconds to delay attempting a reconnection; 0 to perform a reconnection immediately.
Configures the cluster to use a reconnection policy that waits exponentially longer between each reconnection attempt; however will maintain a constant delay once the maximum delay is reached.
Default:
2000 milliseconds base delay
60000 milliseconds max delay
Note: A random amount of jitter (+/- 15%) will be added to the pure exponential delay value. This helps to prevent situations where multiple connections are in the reconnection process at exactly the same time. The jitter will never cause the delay to be less than the base delay, or more than the max delay.
cluster – [in]
base_delay_ms – [in] The base delay (in milliseconds) to use for scheduling reconnection attempts.
max_delay_ms – [in] The maximum delay to wait between two reconnection attempts.

Sets the amount of time, in microseconds, to wait for new requests to coalesce into a single system call. This should be set to a value around the latency SLA of your application’s requests while also considering the request’s roundtrip time. Larger values should be used for throughput bound workloads and lower values should be used for latency bound workloads.
Default: 200 us
cluster – [in]

CASS_OK if successful, otherwise an error occurred.
Sets the ratio of time spent processing new requests versus handling the I/O and processing of outstanding requests. The range of this setting is 1 to 100, where larger values allocate more time to processing new requests and smaller values allocate more time to processing outstanding requests.

Configures the cluster to use round-robin load balancing.
The driver discovers all nodes in a cluster and cycles through them per request. All are considered ‘local’.
cluster – [in]
Configures the cluster to use DC-aware load balancing. For each query, all live nodes in a primary ‘local’ DC are tried first, followed by any node from other DCs.
Note: This is the default, and does not need to be called unless switching an existing from another policy or changing settings. Without further configuration, a default local_dc is chosen from the first connected contact point, and no remote hosts are considered in query plans. If relying on this mechanism, be sure to use only contact points from the local DC.
The remote DC settings for DC-aware are not suitable for most scenarios that require DC failover. There is also unhandled gap between replication factor number of nodes failing and the full cluster failing. Only the remote DC settings are being deprecated.
cluster – [in]
local_dc – [in] The primary data center to try first
used_hosts_per_remote_dc – [in] The number of hosts used in each remote DC if no hosts are available in the local dc (deprecated)

Configures the cluster to use Rack-aware load balancing. For each query, all live nodes in a primary ‘local’ rack are tried first, followed by nodes from local DC and then nodes from other DCs.

Configures the cluster to use token-aware request routing or not.
Important: Token-aware routing depends on keyspace metadata. For this reason enabling token-aware routing will also enable retrieving and updating keyspace schema metadata.
Default: cass_true (enabled).
This routing policy composes the base routing policy, routing requests first to replicas on nodes considered ‘local’ by the base load balancing policy.
cluster – [in]
enabled – [in]
Configures token-aware routing to randomly shuffle replicas. This can reduce the effectiveness of server-side caching, but it can better distribute load over replicas for a given partition key.
Note: Token-aware routing must be enabled for the setting to be applicable.
Default: cass_true (enabled).
cluster – [in]
enabled – [in]
Configures the cluster to use latency-aware request routing or not.
Default: cass_false (disabled).
This routing policy is a top-level routing policy. It uses the base routing policy to determine locality (dc-aware) and/or placement (token-aware) before considering the latency.
cluster – [in]
enabled – [in]
Configures the settings for latency-aware request routing.
Defaults:
exclusion_threshold: 2.0
scale_ms: 100 milliseconds
retry_period_ms: 10,000 milliseconds (10 seconds)
update_rate_ms: 100 milliseconds
min_measured: 50
cluster – [in]
exclusion_threshold – [in] Controls how much worse the latency must be compared to the average latency of the best performing node before it penalized.
scale_ms – [in] Controls the weight given to older latencies when calculating the average latency of a node. A bigger scale will give more weight to older latency measurements.
retry_period_ms – [in] The amount of time a node is penalized by the policy before being given a second chance when the current average latency exceeds the calculated threshold (exclusion_threshold * best_average_latency).
update_rate_ms – [in] The rate at which the best average latency is recomputed.
min_measured – [in] The minimum number of measurements per-host required to be considered by the policy.
Sets/Appends whitelist hosts. The first call sets the whitelist hosts and any subsequent calls appends additional hosts. Passing an empty string will clear and disable the whitelist. White space is striped from the hosts.
This policy filters requests to all other policies, only allowing requests to the hosts contained in the whitelist. Any host not in the whitelist will be ignored and a connection will not be established. This policy is useful for ensuring that the driver will only connect to a predefined set of hosts.
Examples: “127.0.0.1” “127.0.0.1,127.0.0.2”
cluster – [in]
hosts – [in] A comma delimited list of addresses. An empty string will clear the whitelist hosts. The string is copied into the cluster configuration; the memory pointed to by this parameter can be freed after this call.

Sets/Appends blacklist hosts. The first call sets the blacklist hosts and any subsequent calls appends additional hosts. Passing an empty string will clear and disable the blacklist. White space is striped from the hosts.

Any host in the blacklist will be ignored and a connection will not be established. This policy is useful for ensuring that the driver will not connect to a predefined set of hosts.

This policy will retry on a read timeout if there was enough replicas, but no data present, on a write timeout if a logged batch request failed to write the batch log, and on a unavailable error it retries using a new host. In all other cases the default policy will return an error.

Enable/Disable retrieving and updating schema metadata. If disabled this is allows the driver to skip over retrieving and updating schema metadata and cass_session_get_schema_meta() will always return an empty object. This can be useful for reducing the startup overhead of short-lived sessions.

Sets the maximum number of “pending write” objects that will be saved for re-use for marshalling new requests. These objects may hold on to a significant amount of memory and reducing the number of these objects may reduce memory usage of the application.
The cost of reducing the value of this setting is potentially slower marshalling of requests prior to sending.

Associates a named execution profile which can be utilized during execution.
