Method Details

prepareTransition

public ActorFuture<Void> prepareTransition(PartitionTransitionContext context,
 long term,
 RaftServer.Role targetRole)

Description copied from interface: PartitionTransitionStep

This method is a hook to prepare steps for a pending transition. This method is deprecated because eventually we want ro remove it. Once removed, all steps need to take the necessary preparatory steps as part of newRaftRole(...).

For a time being, however, this method will be supported. Steps will be called in reverse order and are expected to take any steps to assume a neutral stance

Specified by:

prepareTransition in interface PartitionTransitionStep

transitionTo

public ActorFuture<Void> transitionTo(PartitionTransitionContext context,
 long term,
 RaftServer.Role targetRole)

Description copied from interface: PartitionTransitionStep

This method is called to start the actual transition

Specified by:

transitionTo in interface PartitionTransitionStep

getName

public String getName()

Specified by:

getName in interface PartitionTransitionStep

Returns:

A log-friendly identification of the PartitionTransitionStep.
