- Method Detail
  - nioPoolSize
```
public Cluster.Builder nioPoolSize(int nioPoolSize)
```
    Size of the pool for handling request/response operations. Defaults to the number of available processors.
  - workerPoolSize
```
public Cluster.Builder workerPoolSize(int workerPoolSize)
```
    Size of the pool for handling background work. Defaults to the number of available processors multiplied by 2
  - serializer
```
public Cluster.Builder serializer(String mimeType)
```
    Set the MessageSerializer to use given its MIME type. Note that setting this value this way will not allow specific configuration of the serializer itself. If specific configuration is required please use serializer(MessageSerializer).
  - serializer
```
public Cluster.Builder serializer(Serializers mimeType)
```
    Set the MessageSerializer to use via the Serializers enum. If specific configuration is required please use serializer(MessageSerializer).
  - serializer
```
public Cluster.Builder serializer(MessageSerializer serializer)
```
    Sets the MessageSerializer to use.
  - enableSsl
```
public Cluster.Builder enableSsl(boolean enable)
```
    Enables connectivity over SSL - note that the server should be configured with SSL turned on for this setting to work properly.
  - sslContext
```
public Cluster.Builder sslContext(SslContext sslContext)
```
    Explicitly set the SslContext for when more flexibility is required in the configuration than is allowed by the Cluster.Builder. If this value is set to something other than null then all other related SSL settings are ignored. The enableSsl setting should still be set to true for this setting to take effect.
  - trustCertificateChainFile
```
public Cluster.Builder trustCertificateChainFile(String certificateChainFile)
```
    File location for a SSL Certificate Chain to use when SSL is enabled. If this value is not provided and SSL is enabled, the TrustManager will be established with a self-signed certificate which is NOT suitable for production purposes.
  - keepAliveInterval
```
public Cluster.Builder keepAliveInterval(long keepAliveInterval)
```
    Length of time in milliseconds to wait on an idle connection before sending a keep-alive request. This setting is only relevant to Channelizer implementations that return true for Channelizer.supportsKeepAlive(). Set to zero to disable this feature.
  - keyCertChainFile
```
public Cluster.Builder keyCertChainFile(String keyCertChainFile)
```
    The X.509 certificate chain file in PEM format.
  - keyFile
```
public Cluster.Builder keyFile(String keyFile)
```
    The PKCS#8 private key file in PEM format.
  - keyPassword
```
public Cluster.Builder keyPassword(String keyPassword)
```
    The password of the keyFile, or null if it's not password-protected.
  - minInProcessPerConnection
```
public Cluster.Builder minInProcessPerConnection(int minInProcessPerConnection)
```
    The minimum number of in-flight requests that can occur on a Connection before it is considered for closing on return to the ConnectionPool.
  - maxInProcessPerConnection
```
public Cluster.Builder maxInProcessPerConnection(int maxInProcessPerConnection)
```
    The maximum number of in-flight requests that can occur on a Connection. This represents an indication of how busy a Connection is allowed to be. This number is linked to the maxSimultaneousUsagePerConnection setting, but is slightly different in that it refers to the total number of requests on a Connection. In other words, a Connection might be borrowed once to have multiple requests executed against it. This number controls the maximum number of requests whereas maxInProcessPerConnection controls the times borrowed.
  - maxSimultaneousUsagePerConnection
```
public Cluster.Builder maxSimultaneousUsagePerConnection(int maxSimultaneousUsagePerConnection)
```
    The maximum number of times that a Connection can be borrowed from the pool simultaneously. This represents an indication of how busy a Connection is allowed to be. Set too large and the Connection may queue requests too quickly, rather than wait for an available Connection or create a fresh one. If set too small, the Connection will show as busy very quickly thus forcing waits for available Connection instances in the pool when there is more capacity available.
  - minSimultaneousUsagePerConnection
```
public Cluster.Builder minSimultaneousUsagePerConnection(int minSimultaneousUsagePerConnection)
```
    The minimum number of times that a Connection should be borrowed from the pool before it falls under consideration for closing. If a Connection is not busy and the minConnectionPoolSize is exceeded, then there is no reason to keep that connection open. Set too large and Connection that isn't busy will continue to consume resources when it is not being used. Set too small and Connection instances will be destroyed when the driver might still be busy.
  - maxConnectionPoolSize
```
public Cluster.Builder maxConnectionPoolSize(int maxSize)
```
    The maximum size that the ConnectionPool can grow.
  - minConnectionPoolSize
```
public Cluster.Builder minConnectionPoolSize(int minSize)
```
    The minimum size of the ConnectionPool. When the Client is started, Connection objects will be initially constructed to this size.
  - resultIterationBatchSize
```
public Cluster.Builder resultIterationBatchSize(int size)
```
    Override the server setting that determines how many results are returned per batch.
  - maxWaitForConnection
```
public Cluster.Builder maxWaitForConnection(int maxWait)
```
    The maximum amount of time to wait for a connection to be borrowed from the connection pool.
  - maxWaitForSessionClose
```
public Cluster.Builder maxWaitForSessionClose(int maxWait)
```
    If the connection is using a "session" this setting represents the amount of time in milliseconds to wait for that session to close before timing out where the default value is 3000. Note that the server will eventually clean up dead sessions itself on expiration of the session or during shutdown.
  - maxContentLength
```
public Cluster.Builder maxContentLength(int maxContentLength)
```
    The maximum size in bytes of any request sent to the server. This number should not exceed the same setting defined on the server.
  - channelizer
```
public Cluster.Builder channelizer(String channelizerClass)
```
    Specify the Channelizer implementation to use on the client when creating a Connection.
  - channelizer
```
public Cluster.Builder channelizer(Class channelizerClass)
```
    Specify the Channelizer implementation to use on the client when creating a Connection.
  - reconnectIntialDelay
```
@Deprecated
public Cluster.Builder reconnectIntialDelay(int initialDelay)
```
    Deprecated. As of release 3.2.3, the value of the initial delay is now the same as the reconnectInterval.
    
    Time in milliseconds to wait before attempting to reconnect to a dead host after it has been marked dead.
  - reconnectInterval
```
public Cluster.Builder reconnectInterval(int interval)
```
    Time in milliseconds to wait between retries when attempting to reconnect to a dead host.
  - loadBalancingStrategy
```
public Cluster.Builder loadBalancingStrategy(LoadBalancingStrategy loadBalancingStrategy)
```
    Specifies the load balancing strategy to use on the client side.
  - authProperties
```
public Cluster.Builder authProperties(AuthProperties authProps)
```
    Specifies parameters for authentication to Gremlin Server.
  - credentials
```
public Cluster.Builder credentials(String username,
                                   String password)
```
    Sets the AuthProperties.Property.USERNAME and AuthProperties.Property.PASSWORD properties for authentication to Gremlin Server.
  - protocol
```
public Cluster.Builder protocol(String protocol)
```
    Sets the AuthProperties.Property.PROTOCOL properties for authentication to Gremlin Server.
  - jaasEntry
```
public Cluster.Builder jaasEntry(String jaasEntry)
```
    Sets the AuthProperties.Property.JAAS_ENTRY properties for authentication to Gremlin Server.
  - addContactPoint
```
public Cluster.Builder addContactPoint(String address)
```
    Adds the address of a Gremlin Server to the list of servers a Client will try to contact to send requests to. The address should be parseable by InetAddress.getByName(String). That's the only validation performed at this point. No connection to the host is attempted.
  - addContactPoints
```
public Cluster.Builder addContactPoints(String... addresses)
```
    Add one or more the addresses of a Gremlin Servers to the list of servers a Client will try to contact to send requests to. The address should be parseable by InetAddress.getByName(String). That's the only validation performed at this point. No connection to the host is attempted.
  - port
```
public Cluster.Builder port(int port)
```
    Sets the port that the Gremlin Servers will be listening on.
  - create
```
public Cluster create()
```
