public static final class Eraftpb.ConfChangeV2
extends com.google.protobuf.GeneratedMessageV3
implements Eraftpb.ConfChangeV2OrBuilder

 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
 paper[1], 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.
