With this change the cluster metadata (arbitrary key-value data associated with each node) is now broadcast across the cluster using the standard consensus mechanism. Specifically the use case for this metadata is to allow all nodes know the HTTP API address of all other nodes, for the purpose of redirecting requests to the leader.
This change removed the need for multiplexing two logical connections
over the single Raft TCP connection, which greatly simplifies the
networking code generally.
Original PR https://github.com/rqlite/rqlite/pull/434
The -http-ca-cert and -node-ca-cert options allow the user to specify
trusted X.509 root CA certificates as an alternative to the
-http-no-verify and -node-no-verify options. This behavior is analogous
to the rqlite client -ca-cert option.
* Use resolved Raft address as API peer key
* Allow Raft advertise address to be set
* Better log message for mux
* CHANGELOG updates
* Unit test mux layer address advertise
Integrate TCP mux with cluster and store
This change allows any node, including followers, to use the Raft log to make changes to a cluster-wide state.
