type ConfChangeTransition 

type ConfChangeTransition int32

const (
	// Automatically use the simple protocol if possible, otherwise fall back
	// to ConfChangeJointImplicit. Most applications will want to use this.
	ConfChangeTransitionAuto ConfChangeTransition = 0
	// Use joint consensus unconditionally, and transition out of them
	// automatically (by proposing a zero configuration change).
	//
	// This option is suitable for applications that want to minimize the time
	// spent in the joint configuration and do not store the joint configuration
	// in the state machine (outside of InitialState).
	ConfChangeTransitionJointImplicit ConfChangeTransition = 1
	// Use joint consensus and remain in the joint configuration until the
	// application proposes a no-op configuration change. This is suitable for
	// applications that want to explicitly control the transitions, for example
	// to use a custom payload (via the Context field).
	ConfChangeTransitionJointExplicit ConfChangeTransition = 2

type ConfChangeV2 

type ConfChangeV2 struct {
	Transition ConfChangeTransition `protobuf:"varint,1,opt,name=transition,enum=raftpb.ConfChangeTransition" json:"transition"`
	Changes    []ConfChangeSingle   `protobuf:"bytes,2,rep,name=changes" json:"changes"`
	Context    []byte               `protobuf:"bytes,3,opt,name=context" json:"context,omitempty"`
}

ConfChangeV2 messages initiate configuration changes. They support both the simple "one at a time" membership change protocol and full Joint Consensus allowing for arbitrary changes in membership.

The supplied context is treated as an opaque payload and can be used to attach an action on the state machine to the application of the config change proposal. Note that contrary to Joint Consensus as outlined in the Raft paper1, configuration changes become active when they are *applied* to the state machine (not when they are appended to the log).

The simple protocol can be used whenever only a single change is made.

Non-simple changes require the use of Joint Consensus, for which two configuration changes are run. The first configuration change specifies the desired changes and transitions the Raft group into the joint configuration, in which quorum requires a majority of both the pre-changes and post-changes configuration. Joint Consensus avoids entering fragile intermediate configurations that could compromise survivability. For example, without the use of Joint Consensus and running across three availability zones with a replication factor of three, it is not possible to replace a voter without entering an intermediate configuration that does not survive the outage of one availability zone.

The provided ConfChangeTransition specifies how (and whether) Joint Consensus is used, and assigns the task of leaving the joint configuration either to Raft or the application. Leaving the joint configuration is accomplished by proposing a ConfChangeV2 with only and optionally the Context field populated.

For details on Raft membership changes, see:

func (ConfChangeV2) AsV1 

func (c ConfChangeV2) AsV1() (ConfChange, bool)

AsV1 returns ConfChange{} and false.

func (ConfChangeV2) AsV2 

func (c ConfChangeV2) AsV2() ConfChangeV2

AsV2 is the identity.

func (*ConfChangeV2) Descriptor 

func (*ConfChangeV2) Descriptor() ([]byte, []int)

func (ConfChangeV2) EnterJoint 

func (c ConfChangeV2) EnterJoint() (autoLeave bool, ok bool)

EnterJoint returns two bools. The second bool is true if and only if this config change will use Joint Consensus, which is the case if it contains more than one change or if the use of Joint Consensus was requested explicitly. The first bool can only be true if second one is, and indicates whether the Joint State will be left automatically.

func (ConfChangeV2) LeaveJoint 

func (c ConfChangeV2) LeaveJoint() bool

LeaveJoint is true if the configuration change leaves a joint configuration. This is the case if the ConfChangeV2 is zero, with the possible exception of the Context field.
