Constructor Detail

RiakNode.Builder

public RiakNode.Builder()

Default constructor. Returns a new builder for a RiakNode with default values set.

Method Detail

withRemoteAddress

public RiakNode.Builder withRemoteAddress(String remoteAddress)

Sets the remote address for this RiakNode.

Parameters:

remoteAddress - Can either be a FQDN or IP address

Returns:

this

See Also:

RiakNode.Builder.DEFAULT_REMOTE_ADDRESS

withRemotePort

public RiakNode.Builder withRemotePort(int port)

Specifies the remote port for this RiakNode.

Parameters:

port - - the port

Returns:

this

See Also:

RiakNode.Builder.DEFAULT_REMOTE_PORT

withMinConnections

public RiakNode.Builder withMinConnections(int minConnections)

Set the minimum number of active connections to maintain. These connections are exempt from the idle timeout.

Parameters:

minConnections - - number of connections to maintain.

Returns:

this

See Also:

RiakNode.Builder.DEFAULT_MIN_CONNECTIONS

withMaxConnections

public RiakNode.Builder withMaxConnections(int maxConnections)

Set the maximum number of connections allowed. A value of 0 sets this to unlimited.

Parameters:

maxConnections - - maximum number of connections to allow

Returns:

this

See Also:

RiakNode.Builder.DEFAULT_MAX_CONNECTIONS

withIdleTimeout

public RiakNode.Builder withIdleTimeout(int idleTimeoutInMillis)

Set the idle timeout used to reap inactive connections. Any connection that has been idle for this amount of time becomes eligible to be closed and discarded unless minConnections has been set via RiakNode.Builder.withMinConnections(int)

Parameters:

idleTimeoutInMillis - - idle timeout in milliseconds

Returns:

this

See Also:

RiakNode.Builder.DEFAULT_IDLE_TIMEOUT

withConnectionTimeout

public RiakNode.Builder withConnectionTimeout(int connectionTimeoutInMillis)

Set the connection timeout used when making new connections

Parameters:

connectionTimeoutInMillis -

Returns:

this

See Also:

RiakNode.Builder.DEFAULT_CONNECTION_TIMEOUT

withExecutor

public RiakNode.Builder withExecutor(ScheduledExecutorService executor)

Provides an executor for this node to use for internal maintenance tasks. If not provided one will be created via Executors.newSingleThreadScheduledExecutor()

Parameters:

executor - the ScheduledExecutorService to use.

Returns:

this

withBootstrap

public RiakNode.Builder withBootstrap(io.netty.bootstrap.Bootstrap bootstrap)

Provides a Netty Bootstrap for this node to use. If not provided one will be created with its own NioEventLoopGroup.

Parameters:

bootstrap -

Returns:

this

withBlockOnMaxConnections

public RiakNode.Builder withBlockOnMaxConnections(boolean block)

Set whether to block if all connections are in use.

If a maximum number of connections is specified and all those connections are in use, the default behavior when an operation is submitted to a node is to fail-fast and return. Setting this to true will cause the call to block (fair-scheduled, FIFO) until a connection becomes available.

Parameters:

block - whether to block when an operation is submitted and all connections are in use.

Returns:

this

withAuth

public RiakNode.Builder withAuth(String username,
                        String password,
                        KeyStore trustStore)

Set the credentials for Riak security and authentication.

Riak supports authentication and authorization features. These credentials will be used for all connections.

Note this requires Riak to have been configured with security enabled.

Parameters:

username - the riak user name.

password - the password for this user.

trustStore - A Java KeyStore loaded with the CA certificate required for TLS/SSL

Returns:

a reference to this object.

withHealthCheck

public RiakNode.Builder withHealthCheck(HealthCheckFactory factory)

Set the HealthCheckFactory used to determine if this RiakNode is healthy.

If not set the PingHealthCheck is used.

Parameters:

factory - a HealthCheckFactory instance that produces HealthCheckDecoders

Returns:

a reference to this object.

See Also:

HealthCheckDecoder

build

public RiakNode build()
               throws UnknownHostException

Builds a RiakNode. If a Netty Bootstrap and/or a ScheduledExecutorService has not been provided they will be created.

Returns:

a new Riaknode

Throws:

UnknownHostException - if the DNS lookup fails for the supplied hostname

buildNodes

public static List<RiakNode> buildNodes(RiakNode.Builder builder,
                        List<String> remoteAddresses)
                                 throws UnknownHostException

Build a set of RiakNodes. The provided builder will be used to construct a set of RiakNodes using the supplied addresses.

Parameters:

builder - a configured builder

remoteAddresses - a list of IP addresses or FQDN

Returns:

a list of constructed RiakNodes

Throws:

UnknownHostException - if a supplied FQDN can not be resolved.
