org.elasticsearch.xpack.core.ilm.UnfollowAction

All Implemented Interfaces:

NamedWriteable, Writeable, ToXContent, ToXContentObject, LifecycleAction

public final class UnfollowAction
extends Object
implements LifecycleAction

Converts a CCR following index into a normal, standalone index, once the index is ready to be safely separated.

"Readiness" is composed of two conditions: 1) The index must have LifecycleSettings.LIFECYCLE_INDEXING_COMPLETE set to true, which is done automatically by RolloverAction (or manually). 2) The index must be up to date with the leader, defined as the follower checkpoint being equal to the global checkpoint for all shards.

toSteps

public List<Step> toSteps(Client client,
 String phase,
 Step.StepKey nextStepKey)

Description copied from interface: LifecycleAction

converts the LifecycleAction's execution plan into a series of Steps that reference each other to preserve order of operations.

Specified by:

toSteps in interface LifecycleAction

Parameters:

client - the client that will be used by AsyncActionStep and AsyncWaitStep steps

phase - the name of the phase this action is being executed within

nextStepKey - the next step to execute after this action's steps. If null, then there are no further steps to run. It is the responsibility of each LifecycleAction to implement this correctly and not forget to link to this final step so that the policy can continue.

Returns:

an ordered list of steps that represent the execution plan of the action

isSafeAction

public boolean isSafeAction()

Specified by:

isSafeAction in interface LifecycleAction

Returns:

true if this action is considered safe. An action is not safe if it will produce unwanted side effects or will get stuck when the action configuration is changed while an index is in this action
