Types

	ReleaseLockKeys(ctx context.Context, resourceID string, lockKeys []string) (bool, error)
	SetBranchSessionDead(ctx context.Context, branchSession *api.BranchSession) error
	ListDeadBranchSession(ctx context.Context, applicationID string) ([]*api.BranchSession, error)
	WatchGlobalSessions(ctx context.Context, applicationID string) Watcher
	WatchBranchSessions(ctx context.Context, applicationID string) Watcher
}

type TransactionSession

type TransactionSession interface {
	Marshal() (data []byte, err error)
	Unmarshal(data []byte) error
}

type Watcher

type Watcher interface {
	// Stop watching. Will close the channel returned by ResultChan(). Releases
	// any resources used by the watch.
	Stop()

	// ResultChan return a chan which will receive all the TransactionSessions. If an error occurs
	// or Stop() is called, the implementation will close this channel and
	// release any resources used by the watch.
	ResultChan() <-chan TransactionSession
}

Watcher can be implemented by anything that knows how to watch and report changes.
