Method Details

curator

static ZooKeeperDiscoverySpec curator(String serviceName)

Returns a ZooKeeperDiscoverySpec that is compatible with Curator Service Discovery. This is also compatible with Spring Cloud Zookeeper.

See Also:

• ZooKeeperRegistrationSpec.curator(String)

builderForCurator

static CuratorDiscoverySpecBuilder builderForCurator(String serviceName)

Returns a new CuratorDiscoverySpecBuilder. The specification is compatible with Curator Service Discovery and Spring Cloud Zookeeper.

See Also:

• ZooKeeperRegistrationSpec.builderForCurator(String)

serverSets

static ZooKeeperDiscoverySpec serverSets()

Returns a ZooKeeperDiscoverySpec that is compatible with Finagle ServerSets.

See Also:

• ZooKeeperRegistrationSpec.builderForServerSets()

serverSets

static ZooKeeperDiscoverySpec serverSets(Function<? super ServerSetsInstance,Endpoint> converter)

Returns a ZooKeeperDiscoverySpec that is compatible with Finagle ServerSets.

Parameters:

converter - the converter to convert a ServerSetsInstance to an Endpoint. If you don't want to connect to the service, you can simply return null in the converter.

See Also:

• ZooKeeperRegistrationSpec.builderForServerSets()

legacy

static ZooKeeperDiscoverySpec legacy()

Returns the legacy ZooKeeperDiscoverySpec implementation which assumes a znode value is a comma-separated string. Each element of the znode value represents an Endpoint whose format is <host>[:<port_number>[:weight]], such as:

• "foo.com" - default port number, default weight (1000)
• "bar.com:8080 - port number 8080, default weight (1000)
• "10.0.2.15:0:500 - default port number, weight 500
• "192.168.1.2:8443:700 - port number 8443, weight 700

Note that the port number must be specified when you want to specify the weight.

• ZooKeeperRegistrationSpec.legacy()

path

@Nullable
@Nullable String path()

Returns the path for finding the byte array representation of registered instances. The path is appended to the znodePath that is specified when creating ZooKeeperEndpointGroup.

decode

@Nullable
@Nullable Endpoint decode(byte[] data)

Decodes a znode value to an Endpoint.
