Method Detail

currentNodeAddress

public void currentNodeAddress(java.lang.String host,
                               java.lang.String port,
                               java.lang.String nodeId)

Description copied from interface: ClusterConfiguration

The network address of the current node and unique Node ID. Depending on the concrete Cluster and ClusterBuffer implementation, used in current Reveno instance, this host and port will be used for tcp binding, and Node ID for unique representation of the current node with multicast failover.

Specified by:

currentNodeAddress in interface ClusterConfiguration

Parameters:

host - of the current node in cluster

port - of the current node in cluster

nodeId - unqiue node identificator in among cluster

currentNodeAddress

public void currentNodeAddress(java.lang.String host,
                               java.lang.String port,
                               java.lang.String nodeId,
                               IOMode mode)

Description copied from interface: ClusterConfiguration

The network address of the current node and unique Node ID. Depending on the concrete ClusterProvider implementation, used in current Reveno instance, this host and port will be used for tcp binding, and Node ID for unique representation of the current node with multicast failover.

Specified by:

currentNodeAddress in interface ClusterConfiguration

Parameters:

host - of the current node in cluster

port - of the current node in cluster

nodeId - unqiue node identificator in among cluster

mode - of IO between other nodes

currentNodeAddress

public void currentNodeAddress(Address nodeAddress)

Description copied from interface: ClusterConfiguration

Abstract Address which identifies current node in cluster. It should be provided in the format, which currently used ClusterProvider can understand it.

Specified by:

currentNodeAddress in interface ClusterConfiguration

Parameters:

nodeAddress - of current node in Reveno cluster

currentNodeAddress

public Address currentNodeAddress()

nodesInetAddresses

public void nodesInetAddresses(java.util.List<InetAddress> addresses)

Description copied from interface: ClusterConfiguration

List of other parties network addresses.

Specified by:

nodesInetAddresses in interface ClusterConfiguration

nodesAddresses

public void nodesAddresses(java.util.List<Address> nodeAddresses)

Description copied from interface: ClusterConfiguration

List of other parties addresses.

Specified by:

nodesAddresses in interface ClusterConfiguration

nodesAddresses

public java.util.List<Address> nodesAddresses()

commandsXmitTransport

public void commandsXmitTransport(ClusterConfiguration.CommandsXmitTransport transport)

Description copied from interface: ClusterConfiguration

Denotes the style of network communication which will be used between all nodes in cluster to transfer commands from Master to Slaves. Currently, it supports two possible values: UNICAST and MULTICAST. You should also note, that with any value used here, all communications between nodes are reliable, means the loss or corruption of data is always processed according to the situation, guaranteeing ordering, data integrity, and etc. UNICAST is a one-to one connection between all hosts in cluster. It uses TCP NIO2 under the hood. It is most reliable option since TCP by itself provide ordering and ack capabilities, but in some environments it might scale not so well. MULTICAST works like broadcast, with differences like subscription basis, etc. It uses UDP protocol, which means that no connections to other parties will be opened, and the packet will be sent only once, routed to many. With good network configuration, it scales much better than TCP. But be aware, that usually multicast connections are not possible in internet environment.

Specified by:

commandsXmitTransport in interface ClusterConfiguration

Parameters:

transport - type to be used for commands transfer.

commandsXmitTransport

public ClusterConfiguration.CommandsXmitTransport commandsXmitTransport()

multicast

public ClusterConfiguration.MulticastConfiguration multicast()

Description copied from interface: ClusterConfiguration

Multicast configurations, which will be used in case of ClusterConfiguration.commandsXmitTransport(CommandsXmitTransport) was set to MULTICAST.

Specified by:

multicast in interface ClusterConfiguration

Returns:

multicast configuration

revenoMulticast

public RevenoClusterConfiguration.RevenoMulticastConfiguration revenoMulticast()

unicast

public ClusterConfiguration.UnicastConfiguration unicast()

Description copied from interface: ClusterConfiguration

Unicast configrations, which will be used in cast of ClusterConfiguration.commandsXmitTransport(CommandsXmitTransport) was set to UNICAST.

revenoUnicast

public RevenoClusterConfiguration.RevenoUnicastConfiguration revenoUnicast()

electionTimeouts

public ClusterConfiguration.TimeoutsConfiguration electionTimeouts()

Description copied from interface: ClusterConfiguration

Timeouts which are used during Leadership Election process, which is started usually by membership changes, or some unexpected critical situations.

Specified by:

electionTimeouts in interface ClusterConfiguration

Returns:

timeouts configuration

revenoElectionTimeouts

public RevenoClusterConfiguration.RevenoTimeoutsConfiguration revenoElectionTimeouts()

dataSync

public ClusterConfiguration.SyncConfiguration dataSync()

Description copied from interface: ClusterConfiguration

Data Synchronization configurations. Data Synchronization is a process, which is issued at some stage of Leadership Election process. First, nodes sends to each other their last transaction IDs processed. After that, somes might discover that their internal state is not the last in cluster. In that case, they ask the node with the most actual state to share last transactions / snapshot, efficiently syncing with it. After all nodes share the same state, they can continue to operate.

Specified by:

dataSync in interface ClusterConfiguration

Returns:

sync configuration

revenoDataSync

public RevenoClusterConfiguration.RevenoSyncConfiguration revenoDataSync()

authToken

public void authToken(java.lang.String authToken)

Specified by:

authToken in interface ClusterConfiguration

authToken

public java.lang.String authToken()

priorityInCluster

public void priorityInCluster(int priority)

Description copied from interface: ClusterConfiguration

Priority in cluster, which allows to effectively foresee next elected Masters in case of failure of previous ones. The lower value, the more possibility that this node will be elected as Master in next election round.

Specified by:

priorityInCluster in interface ClusterConfiguration

Parameters:

priority - of the node
