Interface ClusterAwareLifecycleManager

All Known Implementing Classes:

ClusterAwareLifecycleManagerImpl

@Internal
public interface ClusterAwareLifecycleManager

Manages the cluster life cycle. Responsible for setting different states for both the whole cluster and the current node. Use NodeLifecycleProvider to get current node life cycle.

Since:

9.5

Method Details

nodeStarting

void nodeStarting()

Puts the current node into the NodeLifecycleState.STARTING state

nodeRunning

void nodeRunning()

Puts the current node into the NodeLifecycleState.RUNNING state

nodeRunningAsSecondary

void nodeRunningAsSecondary()

Puts the current node into the NodeLifecycleState.RUNNING_AS_SECONDARY state

pauseCluster

CompletableFuture<NodeLifecycleState> pauseCluster()

Submits pause cluster request.

Returns:

Future for pause cluster operation

pauseCluster

CompletableFuture<NodeLifecycleState> pauseCluster(@NotNull
 @NotNull NodeLifecycleState fakeNodeLifecycleState)

Submits pause cluster request with the context of the current node state being fakeNodeLifecycleState. This method is considered extremely unsafe because calling it might end up with an undermined node state.

Parameters:

fakeNodeLifecycleState - Node state in which context the pause cluster request is executed

Returns:

Future for force pause cluster operation

prepareNodeForRestart

@NotNull
@NotNull NodeLifecycleState prepareNodeForRestart()

Puts the current node into the NodeLifecycleState.PREPARING_FOR_RESTART state

Returns:

NodeLifecycleState of the current node

resumeCluster

@NotNull
@NotNull NodeLifecycleState resumeCluster()

Puts the cluster into the NodeLifecycleState.RUNNING state

Returns:

NodeLifecycleState of the current node

getNodeLifecycleState

@NotNull
@NotNull NodeLifecycleState getNodeLifecycleState()

Returns:

gets the NodeLifecycleState of the current node

getBufferedNodeLifecycleState

@NotNull
@NotNull NodeLifecycleState getBufferedNodeLifecycleState()

Returns:

gets the cached NodeLifecycleState of the current node, the result is eventually consistent

refreshNodeLifecycleState

boolean refreshNodeLifecycleState()

Refreshes the cached NodeLifecycleState

Returns:

whether the refresh was successfully performed

getClusterLifecycleState

@NotNull
@NotNull ClusterLifecycleState getClusterLifecycleState()

Returns:

gets the ClusterLifecycleState of the cluster
