backupRemotely

<O> XSiteResponse<O> backupRemotely(XSiteBackup backup,
 XSiteRequest<O> rpcCommand)

Sends a cross-site request to a remote site.

Currently, no reply values are supported. Or the request completes successfully or it throws an Exception.

If XSiteBackup.isSync() returns false, the XSiteResponse is only completed when the an ACK from the remote site is received. The invoker needs to make sure not to wait for the XSiteResponse.

Parameters:

backup - The remote site.

rpcCommand - The command to send.

Returns:

A XSiteResponse that is completed when the request is completed.

isCoordinator

boolean isCoordinator()

Returns:

true if the current Channel is the coordinator of the cluster.

getCoordinator

Address getCoordinator()

Returns:

the Address of the current coordinator.

getAddress

Address getAddress()

Retrieves the current cache instance's network address

Returns:

an Address

getPhysicalAddresses

List<Address> getPhysicalAddresses()

Retrieves the current cache instance's physical network addresses. Some implementations might differentiate between logical and physical addresses in which case, this method allows clients to query the physical ones associated with the logical address. Implementations where logical and physical address are the same will simply return a single entry List that contains the same Address as getAddress().

Returns:

an List of Address

getMembers

List<Address> getMembers()

Returns a list of members in the current cluster view.

Returns:

a list of members. Typically, this would be defensively copied.

getMembersPhysicalAddresses

List<Address> getMembersPhysicalAddresses()

Returns physical addresses of members in the current cluster view.

Returns:

a list of physical addresses

isMulticastCapable

boolean isMulticastCapable()

Tests whether the transport supports true multicast

Returns:

true if the transport supports true multicast

checkCrossSiteAvailable

void checkCrossSiteAvailable()
                      throws org.infinispan.commons.CacheConfigurationException

Checks if this Transport is able to perform cross-site requests.

Throws:

org.infinispan.commons.CacheConfigurationException - if cross-site isn't available.

localSiteName

String localSiteName()

Returns:

The local site name or null if this Transport cannot make cross-site requests.

localNodeName

default String localNodeName()

Returns:

The local node name, defaults to the local node address.

start

void start()

Specified by:

start in interface org.infinispan.commons.api.Lifecycle

stop

void stop()

Specified by:

stop in interface org.infinispan.commons.api.Lifecycle

getViewId

int getViewId()

Throws:

org.infinispan.commons.CacheException - if the transport has been stopped.

withView

CompletableFuture<Void> withView(int expectedViewId)

Returns:

A CompletableFuture that completes when the transport has installed the expected view.

getLog

Log getLog()

@Deprecated(forRemoval=true,
            since="11.0")
default void checkTotalOrderSupported()

Deprecated, for removal: This API element is subject to removal in a future version.

Total order support dropped

check if the transport has configured with total order deliver properties (has the sequencer in JGroups protocol stack.

getSitesView

Set<String> getSitesView()

Get the view of interconnected sites. If no cross site replication has been configured, this method returns null. Inspecting the site view can be useful to see if the different sites have managed to join each other, which is pre-requisite to get cross replication working.

Returns:

set containing the connected sites, or null if no cross site replication has been enabled.

isSiteCoordinator

boolean isSiteCoordinator()

Returns:

true if this node is a cross-site replication coordinator.

getRelayNodesAddress

Collection<Address> getRelayNodesAddress()

Returns:

The current site coordinators Address.

invokeCommand

@Experimental
default <T> CompletionStage<T> invokeCommand(Address target,
 ReplicableCommand command,
 ResponseCollector<T> collector,
 DeliverOrder deliverOrder,
 long timeout,
 TimeUnit unit)

Invoke a command on a single node and pass the response to a ResponseCollector.

If the target is the local node, the command is never executed and ResponseCollector.finish() is called directly.

Since:

9.1

invokeCommand

@Experimental
default <T> CompletionStage<T> invokeCommand(Collection<Address> targets,
 ReplicableCommand command,
 ResponseCollector<T> collector,
 DeliverOrder deliverOrder,
 long timeout,
 TimeUnit unit)

Invoke a command on a collection of node and pass the responses to a ResponseCollector.

If one of the targets is the local node, it is ignored. The command is only executed on the remote nodes.

Since:

9.1

invokeCommandOnAll

@Experimental
default <T> CompletionStage<T> invokeCommandOnAll(ReplicableCommand command,
 ResponseCollector<T> collector,
 DeliverOrder deliverOrder,
 long timeout,
 TimeUnit unit)

Invoke a command on all the nodes in the cluster and pass the responses to a ResponseCollector.

The command is not executed locally and it is not sent across RELAY2 bridges to remote sites.

Since:

9.1

invokeCommandOnAll

@Experimental
default <T> CompletionStage<T> invokeCommandOnAll(Collection<Address> requiredTargets,
 ReplicableCommand command,
 ResponseCollector<T> collector,
 DeliverOrder deliverOrder,
 long timeout,
 TimeUnit unit)

Invoke a command on all the nodes in the cluster and pass the responses to a ResponseCollector.

he command is not executed locally and it is not sent across RELAY2 bridges to remote sites.

Since:

9.3

invokeCommandStaggered

@Experimental
default <T> CompletionStage<T> invokeCommandStaggered(Collection<Address> targets,
 ReplicableCommand command,
 ResponseCollector<T> collector,
 DeliverOrder deliverOrder,
 long timeout,
 TimeUnit unit)

Invoke a command on a collection of nodes and pass the responses to a ResponseCollector.

The command is only sent immediately to the first target, and there is an implementation-dependent delay before sending the command to each target. There is no delay if the target responds or leaves the cluster. The remaining targets are skipped if ResponseCollector.addResponse(Address, Response) returns a non-null value.

The command is only executed on the remote nodes.

Since:

9.1
