+// ConfChangeV2 messages initiate configuration changes. They support both the

+// 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.
