Method Details

toFollower

ActorFuture<Void> toFollower(long currentTerm)

Transitions to follower asynchronously by closing the current partition's components and opening a follower partition.

Parameters:

currentTerm - the current term on which the transition happens

Returns:

an ActorFuture to be completed when the transition is complete. Completed exceptionally with PartitionTransition.CancelledPartitionTransition if the partition was cancelled.

toLeader

ActorFuture<Void> toLeader(long currentTerm)

Transitions to leader asynchronously by closing the current partition's components and opening a leader partition.

Parameters:

currentTerm - the current term on which the transition happens

Returns:

an ActorFuture to be completed when the transition is complete. Completed exceptionally * with PartitionTransition.CancelledPartitionTransition if the partition was cancelled.

toInactive

ActorFuture<Void> toInactive(long term)

Closes the current partition's components asynchronously.

Parameters:

term -

Returns:

an ActorFuture completed when the transition is complete. Completed exceptionally * with PartitionTransition.CancelledPartitionTransition if the partition was cancelled.

setConcurrencyControl

void setConcurrencyControl(ConcurrencyControl concurrencyControl)

Sets the ConcurrencyControl through which tasks are executed.

Parameters:

concurrencyControl - the concurrency control

updateTransitionContext

void updateTransitionContext(PartitionTransitionContext transitionContext)

Sets the transition context

Parameters:

transitionContext - the context to be used

getHealthIssue

HealthIssue getHealthIssue()

Returns:

null if transition is healthy or a HealthIssue if not.
