-# etcd/client
-
-etcd/client is the Go client library for etcd.
-
-[](https://godoc.org/go.etcd.io/etcd/client)
-
-For full compatibility, it is recommended to vendor builds using etcd's vendored packages, using tools like `golang/dep`, as in [vendor directories](https://golang.org/cmd/go/#hdr-Vendor_Directories).
-
-## Install
-
-```bash
-go get go.etcd.io/etcd/client
-```
-
-## Usage
-
-```go
-package main
-
-import (
- "log"
- "time"
- "context"
-
- "go.etcd.io/etcd/client"
-)
-
-func main() {
- cfg := client.Config{
- Endpoints: []string{"http://127.0.0.1:2379"},
- Transport: client.DefaultTransport,
- // set timeout per request to fail fast when the target endpoint is unavailable
- HeaderTimeoutPerRequest: time.Second,
- }
- c, err := client.New(cfg)
- if err != nil {
- log.Fatal(err)
- }
- kapi := client.NewKeysAPI(c)
- // set "/foo" key with "bar" value
- log.Print("Setting '/foo' key with 'bar' value")
- resp, err := kapi.Set(context.Background(), "/foo", "bar", nil)
- if err != nil {
- log.Fatal(err)
- } else {
- // print common key info
- log.Printf("Set is done. Metadata is %q\n", resp)
- }
- // get "/foo" key's value
- log.Print("Getting '/foo' key value")
- resp, err = kapi.Get(context.Background(), "/foo", nil)
- if err != nil {
- log.Fatal(err)
- } else {
- // print common key info
- log.Printf("Get is done. Metadata is %q\n", resp)
- // print value
- log.Printf("%q key has %q value\n", resp.Node.Key, resp.Node.Value)
- }
-}
-```
-
-## Error Handling
-
-etcd client might return three types of errors.
-
-- context error
-
-Each API call has its first parameter as `context`. A context can be canceled or have an attached deadline. If the context is canceled or reaches its deadline, the responding context error will be returned no matter what internal errors the API call has already encountered.
-
-- cluster error
-
-Each API call tries to send request to the cluster endpoints one by one until it successfully gets a response. If a requests to an endpoint fails, due to exceeding per request timeout or connection issues, the error will be added into a list of errors. If all possible endpoints fail, a cluster error that includes all encountered errors will be returned.
-
-- response error
-
-If the response gets from the cluster is invalid, a plain string error will be returned. For example, it might be a invalid JSON error.
-
-Here is the example code to handle client errors:
-
-```go
-cfg := client.Config{Endpoints: []string{"http://etcd1:2379","http://etcd2:2379","http://etcd3:2379"}}
-c, err := client.New(cfg)
-if err != nil {
- log.Fatal(err)
-}
-
-kapi := client.NewKeysAPI(c)
-resp, err := kapi.Set(ctx, "test", "bar", nil)
-if err != nil {
- if err == context.Canceled {
- // ctx is canceled by another routine
- } else if err == context.DeadlineExceeded {
- // ctx is attached with a deadline and it exceeded
- } else if cerr, ok := err.(*client.ClusterError); ok {
- // process (cerr.Errors)
- } else {
- // bad cluster endpoints, which are not etcd servers
- }
-}
-```
-
-
-## Caveat
-
-1. etcd/client prefers to use the same endpoint as long as the endpoint continues to work well. This saves socket resources, and improves efficiency for both client and server side. This preference doesn't remove consistency from the data consumed by the client because data replicated to each etcd member has already passed through the consensus process.
-
-2. etcd/client does round-robin rotation on other available endpoints if the preferred endpoint isn't functioning properly. For example, if the member that etcd/client connects to is hard killed, etcd/client will fail on the first attempt with the killed member, and succeed on the second attempt with another member. If it fails to talk to all available endpoints, it will return all errors happened.
-
-3. Default etcd/client cannot handle the case that the remote server is SIGSTOPed now. TCP keepalive mechanism doesn't help in this scenario because operating system may still send TCP keep-alive packets. Over time we'd like to improve this functionality, but solving this issue isn't high priority because a real-life case in which a server is stopped, but the connection is kept alive, hasn't been brought to our attention.
-
-4. etcd/client cannot detect whether a member is healthy with watches and non-quorum read requests. If the member is isolated from the cluster, etcd/client may retrieve outdated data. Instead, users can either issue quorum read requests or monitor the /health endpoint for member health information.

-Package client provides bindings for the etcd APIs.
-
-Create a Config and exchange it for a Client:
-
- import (
- "net/http"
- "context"
-
- "go.etcd.io/etcd/client"
- )
-
- cfg := client.Config{
- Endpoints: []string{"http://127.0.0.1:2379"},
- Transport: DefaultTransport,
- }
-
- c, err := client.New(cfg)
- if err != nil {
- // handle error
- }
-
-Clients are safe for concurrent use by multiple goroutines.
-
-Create a KeysAPI using the Client, then use it to interact with etcd:
-
- kAPI := client.NewKeysAPI(c)
-
- // create a new key /foo with the value "bar"
- _, err = kAPI.Create(context.Background(), "/foo", "bar")
- if err != nil {
- // handle error
- }
-
- // delete the newly created key only if the value is still "bar"
- _, err = kAPI.Delete(context.Background(), "/foo", &DeleteOptions{PrevValue: "bar"})
- if err != nil {
- // handle error
- }
-
-Use a custom context to set timeouts on your operations:
-
- import "time"
-
- ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
- defer cancel()
-
- // set a new key, ignoring its previous state
- _, err := kAPI.Set(ctx, "/ping", "pong", nil)
- if err != nil {
- if err == context.DeadlineExceeded {
- // request took longer than 5s
- } else {
- // handle error
- }
- }

-# etcd/clientv3
-
-[](https://etcd.io/docs)
-[](https://godoc.org/go.etcd.io/etcd/clientv3)
-
-`etcd/clientv3` is the official Go etcd client for v3.
-
-## Install
-
-```bash
-go get go.etcd.io/etcd/clientv3
-```
-
-## Get started
-
-Create client using `clientv3.New`:
-
-```go
-cli, err := clientv3.New(clientv3.Config{
- Endpoints: []string{"localhost:2379", "localhost:22379", "localhost:32379"},
- DialTimeout: 5 * time.Second,
-})
-if err != nil {
- // handle error!
-}
-defer cli.Close()
-```
-
-etcd v3 uses [`gRPC`](https://www.grpc.io) for remote procedure calls. And `clientv3` uses
-[`grpc-go`](https://github.com/grpc/grpc-go) to connect to etcd. Make sure to close the client after using it.
-If the client is not closed, the connection will have leaky goroutines. To specify client request timeout,
-pass `context.WithTimeout` to APIs:
-
-```go
-ctx, cancel := context.WithTimeout(context.Background(), timeout)
-resp, err := cli.Put(ctx, "sample_key", "sample_value")
-cancel()
-if err != nil {
- // handle error!
-}
-// use the response
-```
-
-For full compatibility, it is recommended to vendor builds using etcd's vendored packages, using tools like `golang/dep`, as in [vendor directories](https://golang.org/cmd/go/#hdr-Vendor_Directories).
-
-## Error Handling
-
-etcd client returns 2 types of errors:
-
-1. context error: canceled or deadline exceeded.
-2. gRPC error: see [api/v3rpc/rpctypes](https://godoc.org/go.etcd.io/etcd/etcdserver/api/v3rpc/rpctypes).
-
-Here is the example code to handle client errors:
-
-```go
-resp, err := cli.Put(ctx, "", "")
-if err != nil {
- switch err {
- case context.Canceled:
- log.Fatalf("ctx is canceled by another routine: %v", err)
- case context.DeadlineExceeded:
- log.Fatalf("ctx is attached with a deadline is exceeded: %v", err)
- case rpctypes.ErrEmptyKey:
- log.Fatalf("client-side error: %v", err)
- default:
- log.Fatalf("bad cluster endpoints, which are not etcd servers: %v", err)
- }
-}
-```
-
-## Metrics
-
-The etcd client optionally exposes RPC metrics through [go-grpc-prometheus](https://github.com/grpc-ecosystem/go-grpc-prometheus). See the [examples](https://github.com/etcd-io/etcd/blob/master/clientv3/example_metrics_test.go).
-
-## Namespacing
-
-The [namespace](https://godoc.org/go.etcd.io/etcd/clientv3/namespace) package provides `clientv3` interface wrappers to transparently isolate client requests to a user-defined prefix.
-
-## Request size limit
-
-Client request size limit is configurable via `clientv3.Config.MaxCallSendMsgSize` and `MaxCallRecvMsgSize` in bytes. If none given, client request send limit defaults to 2 MiB including gRPC overhead bytes. And receive limit defaults to `math.MaxInt32`.
-
-## Examples
-
-More code examples can be found at [GoDoc](https://godoc.org/go.etcd.io/etcd/clientv3).

-// From google paxosdb paper:

-// and consists of three components:
-// 1. A list of tests called guard. Each test in guard checks a single entry in the database. It may check
-// for the absence or presence of a value, or compare with a given value. Two different tests in the guard
-// may apply to the same or different entries in the database. All tests in the guard are applied and
-// MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise
-// it executes f op (see item 3 below).
-// 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or
-// lookup operation, and applies to a single database entry. Two different operations in the list may apply
-// to the same or different entries in the database. These operations are executed
-// if guard evaluates to
-// true.
-// 3. A list of database operations called f op. Like t op, but executed if guard evaluates to false.

-// lookup operation, and applies to a single database entry. Two different operations in the list may apply
-// to the same or different entries in the database. These operations are executed

-## Red-Black Tree
-
-*"Introduction to Algorithms" (Cormen et al, 3rd ed.), Chapter 13*
-
-1. Every node is either red or black.
-2. The root is black.
-3. Every leaf (NIL) is black.
-4. If a node is red, then both its children are black.
-5. For each node, all simple paths from the node to descendant leaves contain the
-same number of black nodes.
-
-For example,
-
-```go
-import (
- "fmt"
-
- "go.etcd.io/etcd/pkg/adt"
-)
-
-func main() {
- ivt := adt.NewIntervalTree()
- ivt.Insert(NewInt64Interval(510, 511), 0)
- ivt.Insert(NewInt64Interval(82, 83), 0)
- ivt.Insert(NewInt64Interval(830, 831), 0)
- ...
-```
-
-After inserting the values `510`, `82`, `830`, `11`, `383`, `647`, `899`, `261`, `410`, `514`, `815`, `888`, `972`, `238`, `292`, `953`.
-
-
-
-Deleting the node `514` should not trigger any rebalancing:
-
-
-
-Deleting the node `11` triggers multiple rotates for rebalancing:

-# Raft library
-
-Raft is a protocol with which a cluster of nodes can maintain a replicated state machine.
-The state machine is kept in sync through the use of a replicated log.
-For more details on Raft, see "In Search of an Understandable Consensus Algorithm"
-(https://raft.github.io/raft.pdf) by Diego Ongaro and John Ousterhout.
-
-This Raft library is stable and feature complete. As of 2016, it is **the most widely used** Raft library in production, serving tens of thousands clusters each day. It powers distributed systems such as etcd, Kubernetes, Docker Swarm, Cloud Foundry Diego, CockroachDB, TiDB, Project Calico, Flannel, and more.
-
-Most Raft implementations have a monolithic design, including storage handling, messaging serialization, and network transport. This library instead follows a minimalistic design philosophy by only implementing the core raft algorithm. This minimalism buys flexibility, determinism, and performance.
-
-To keep the codebase small as well as provide flexibility, the library only implements the Raft algorithm; both network and disk IO are left to the user. Library users must implement their own transportation layer for message passing between Raft peers over the wire. Similarly, users must implement their own storage layer to persist the Raft log and state.
-
-In order to easily test the Raft library, its behavior should be deterministic. To achieve this determinism, the library models Raft as a state machine. The state machine takes a `Message` as input. A message can either be a local timer update or a network message sent from a remote peer. The state machine's output is a 3-tuple `{[]Messages, []LogEntries, NextState}` consisting of an array of `Messages`, `log entries`, and `Raft state changes`. For state machines with the same state, the same state machine input should always generate the same state machine output.
-
-A simple example application, _raftexample_, is also available to help illustrate how to use this package in practice: https://github.com/etcd-io/etcd/tree/master/contrib/raftexample
-
-# Features
-
-This raft implementation is a full feature implementation of Raft protocol. Features includes:
-
-- Leader election
-- Log replication
-- Log compaction
-- Membership changes
-- Leadership transfer extension
-- Efficient linearizable read-only queries served by both the leader and followers
- - leader checks with quorum and bypasses Raft log before processing read-only queries
- - followers asks leader to get a safe read index before processing read-only queries
-- More efficient lease-based linearizable read-only queries served by both the leader and followers
- - leader bypasses Raft log and processing read-only queries locally
- - followers asks leader to get a safe read index before processing read-only queries
- - this approach relies on the clock of the all the machines in raft group
-
-This raft implementation also includes a few optional enhancements:
-
-- Optimistic pipelining to reduce log replication latency
-- Flow control for log replication
-- Batching Raft messages to reduce synchronized network I/O calls
-- Batching log entries to reduce disk synchronized I/O
-- Writing to leader's disk in parallel
-- Internal proposal redirection from followers to leader
-- Automatic stepping down when the leader loses quorum
-- Protection against unbounded log growth when quorum is lost

-
-## Usage
-
-The primary object in raft is a Node. Either start a Node from scratch using raft.StartNode or start a Node from some initial state using raft.RestartNode.
-
-To start a three-node cluster
-```go
- storage := raft.NewMemoryStorage()
- c := &Config{
- ID: 0x01,
- ElectionTick: 10,
- HeartbeatTick: 1,
- Storage: storage,
- MaxSizePerMsg: 4096,
- MaxInflightMsgs: 256,
- }
- // Set peer list to the other nodes in the cluster.
- // Note that they need to be started separately as well.
- n := raft.StartNode(c, []raft.Peer{{ID: 0x02}, {ID: 0x03}})
-```
-
-Start a single node cluster, like so:
-```go
- // Create storage and config as shown above.
- // Set peer list to itself, so this node can become the leader of this single-node cluster.
- peers := []raft.Peer{{ID: 0x01}}
- n := raft.StartNode(c, peers)
-```
-
-To allow a new node to join this cluster, do not pass in any peers. First, add the node to the existing cluster by calling `ProposeConfChange` on any existing node inside the cluster. Then, start the node with an empty peer list, like so:
-```go
- // Create storage and config as shown above.
- n := raft.StartNode(c, nil)
-```
-
-To restart a node from previous state:
-```go
- storage := raft.NewMemoryStorage()
-
- // Recover the in-memory storage from persistent snapshot, state and entries.
- storage.ApplySnapshot(snapshot)
- storage.SetHardState(state)
- storage.Append(entries)
-
- c := &Config{
- ID: 0x01,
- ElectionTick: 10,
- HeartbeatTick: 1,
- Storage: storage,
- MaxSizePerMsg: 4096,
- MaxInflightMsgs: 256,
- }
-
- // Restart raft without peer information.
- // Peer information is already included in the storage.
- n := raft.RestartNode(c)
-```
-
-After creating a Node, the user has a few responsibilities:
-
-First, read from the Node.Ready() channel and process the updates it contains. These steps may be performed in parallel, except as noted in step 2.
-
-1. Write Entries, HardState and Snapshot to persistent storage in order, i.e. Entries first, then HardState and Snapshot if they are not empty. If persistent storage supports atomic writes then all of them can be written together. Note that when writing an Entry with Index i, any previously-persisted entries with Index >= i must be discarded.
-
-2. Send all Messages to the nodes named in the To field. It is important that no messages be sent until the latest HardState has been persisted to disk, and all Entries written by any previous Ready batch (Messages may be sent while entries from the same batch are being persisted). To reduce the I/O latency, an optimization can be applied to make leader write to disk in parallel with its followers (as explained at section 10.2.1 in Raft thesis). If any Message has type MsgSnap, call Node.ReportSnapshot() after it has been sent (these messages may be large). Note: Marshalling messages is not thread-safe; it is important to make sure that no new entries are persisted while marshalling. The easiest way to achieve this is to serialise the messages directly inside the main raft loop.
-
-3. Apply Snapshot (if any) and CommittedEntries to the state machine. If any committed Entry has Type EntryConfChange, call Node.ApplyConfChange() to apply it to the node. The configuration change may be cancelled at this point by setting the NodeID field to zero before calling ApplyConfChange (but ApplyConfChange must be called one way or the other, and the decision to cancel must be based solely on the state machine and not external information such as the observed health of the node).
-
-4. Call Node.Advance() to signal readiness for the next batch of updates. This may be done at any time after step 1, although all updates must be processed in the order they were returned by Ready.
-
-Second, all persisted log entries must be made available via an implementation of the Storage interface. The provided MemoryStorage type can be used for this (if repopulating its state upon a restart), or a custom disk-backed implementation can be supplied.
-
-Third, after receiving a message from another node, pass it to Node.Step:
-
-```go
- func recvRaftRPC(ctx context.Context, m raftpb.Message) {
- n.Step(ctx, m)
- }
-```
-
-Finally, call `Node.Tick()` at regular intervals (probably via a `time.Ticker`). Raft has two important timeouts: heartbeat and the election timeout. However, internally to the raft package time is represented by an abstract "tick".
-
-The total state machine handling loop will look something like this:
-
-```go
- for {
- select {
- case <-s.Ticker:
- n.Tick()
- case rd := <-s.Node.Ready():
- saveToStorage(rd.HardState, rd.Entries, rd.Snapshot)
- send(rd.Messages)
- if !raft.IsEmptySnap(rd.Snapshot) {
- processSnapshot(rd.Snapshot)
- }
- for _, entry := range rd.CommittedEntries {
- process(entry)
- if entry.Type == raftpb.EntryConfChange {
- var cc raftpb.ConfChange
- cc.Unmarshal(entry.Data)
- s.Node.ApplyConfChange(cc)
- }
- }
- s.Node.Advance()
- case <-s.done:
- return
- }
- }
-```
-
-To propose changes to the state machine from the node to take application data, serialize it into a byte slice and call:
-
-```go
- n.Propose(ctx, data)
-```
-
-If the proposal is committed, data will appear in committed entries with type raftpb.EntryNormal. There is no guarantee that a proposed command will be committed; the command may have to be reproposed after a timeout.
-
-To add or remove node in a cluster, build ConfChange struct 'cc' and call:
-
-```go
- n.ProposeConfChange(ctx, cc)
-```
-
-After config change is committed, some committed entry with type raftpb.EntryConfChange will be returned. This must be applied to node through:
-
-```go
- var cc raftpb.ConfChange
- cc.Unmarshal(data)
- n.ApplyConfChange(cc)
-```
-
-Note: An ID represents a unique node in a cluster for all time. A
-given ID MUST be used only once even if the old node has been removed.
-This means that for example IP addresses make poor node IDs since they
-may be reused. Node IDs must be non-zero.
-
-## Implementation notes
-
-This implementation is up to date with the final Raft thesis (https://github.com/ongardie/dissertation/blob/master/stanford.pdf), although this implementation of the membership change protocol differs somewhat from that described in chapter 4. The key invariant that membership changes happen one node at a time is preserved, but in our implementation the membership change takes effect when its entry is applied, not when it is added to the log (so the entry is committed under the old membership instead of the new). This is equivalent in terms of safety, since the old and new configurations are guaranteed to overlap.
-
-To ensure there is no attempt to commit two membership changes at once by matching log positions (which would be unsafe since they should have different quorum requirements), any proposed membership change is simply disallowed while any uncommitted change appears in the leader's log.
-
-This approach introduces a problem when removing a member from a two-member cluster: If one of the members dies before the other one receives the commit of the confchange entry, then the member cannot be removed any more since the cluster cannot make progress. For this reason it is highly recommended to use three or more nodes in every cluster.

-## Progress
-
-Progress represents a follower’s progress in the view of the leader. Leader maintains progresses of all followers, and sends `replication message` to the follower based on its progress.
-
-`replication message` is a `msgApp` with log entries.
-
-A progress has two attribute: `match` and `next`. `match` is the index of the highest known matched entry. If leader knows nothing about follower’s replication status, `match` is set to zero. `next` is the index of the first entry that will be replicated to the follower. Leader puts entries from `next` to its latest one in next `replication message`.
-
-A progress is in one of the three state: `probe`, `replicate`, `snapshot`.
-
-```
- +--------------------------------------------------------+
- | send snapshot |
- | |
- +---------+----------+ +----------v---------+
- +---> probe | | snapshot |
- | | max inflight = 1 <----------------------------------+ max inflight = 0 |
- | +---------+----------+ +--------------------+
- | | 1. snapshot success
- | | (next=snapshot.index + 1)
- | | 2. snapshot failure
- | | (no change)
- | | 3. receives msgAppResp(rej=false&&index>lastsnap.index)
- | | (match=m.index,next=match+1)
-receives msgAppResp(rej=true)
-(next=match+1)| |
- | |
- | |
- | | receives msgAppResp(rej=false&&index>match)
- | | (match=m.index,next=match+1)
- | |
- | |
- | |
- | +---------v----------+
- | | replicate |
- +---+ max inflight = n |
- +--------------------+
-```
-
-When the progress of a follower is in `probe` state, leader sends at most one `replication message` per heartbeat interval. The leader sends `replication message` slowly and probing the actual progress of the follower. A `msgHeartbeatResp` or a `msgAppResp` with reject might trigger the sending of the next `replication message`.
-
-When the progress of a follower is in `replicate` state, leader sends `replication message`, then optimistically increases `next` to the latest entry sent. This is an optimized state for fast replicating log entries to the follower.
-
-When the progress of a follower is in `snapshot` state, leader stops sending any `replication message`.
-
-A newly elected leader sets the progresses of all the followers to `probe` state with `match` = 0 and `next` = last index. The leader slowly (at most once per heartbeat) sends `replication message` to the follower and probes its progress.
-
-A progress changes to `replicate` when the follower replies with a non-rejection `msgAppResp`, which implies that it has matched the index sent. At this point, leader starts to stream log entries to the follower fast. The progress will fall back to `probe` when the follower replies a rejection `msgAppResp` or the link layer reports the follower is unreachable. We aggressively reset `next` to `match`+1 since if we receive any `msgAppResp` soon, both `match` and `next` will increase directly to the `index` in `msgAppResp`. (We might end up with sending some duplicate entries when aggressively reset `next` too low. see open question)
-
-A progress changes from `probe` to `snapshot` when the follower falls very far behind and requires a snapshot. After sending `msgSnap`, the leader waits until the success, failure or abortion of the previous snapshot sent. The progress will go back to `probe` after the sending result is applied.
-
-### Flow Control
-
-1. limit the max size of message sent per message. Max should be configurable.
-Lower the cost at probing state as we limit the size per message; lower the penalty when aggressively decreased to a too low `next`
-
-2. limit the # of in flight messages < N when in `replicate` state. N should be configurable. Most implementation will have a sending buffer on top of its actual network transport layer (not blocking raft node). We want to make sure raft does not overflow that buffer, which can cause message dropping and triggering a bunch of unnecessary resending repeatedly.

-Package raft sends and receives messages in the Protocol Buffer format
-defined in the raftpb package.
-
-Raft is a protocol with which a cluster of nodes can maintain a replicated state machine.
-The state machine is kept in sync through the use of a replicated log.
-For more details on Raft, see "In Search of an Understandable Consensus Algorithm"
-(https://raft.github.io/raft.pdf) by Diego Ongaro and John Ousterhout.
-
-A simple example application, _raftexample_, is also available to help illustrate
-how to use this package in practice:
-https://github.com/etcd-io/etcd/tree/master/contrib/raftexample
-
-Usage
-
-The primary object in raft is a Node. You either start a Node from scratch
-using raft.StartNode or start a Node from some initial state using raft.RestartNode.
-
-To start a node from scratch:
-
- storage := raft.NewMemoryStorage()
- c := &Config{
- ID: 0x01,
- ElectionTick: 10,
- HeartbeatTick: 1,
- Storage: storage,
- MaxSizePerMsg: 4096,
- MaxInflightMsgs: 256,
- }
- n := raft.StartNode(c, []raft.Peer{{ID: 0x02}, {ID: 0x03}})
-
-To restart a node from previous state:
-
- storage := raft.NewMemoryStorage()
-
- // recover the in-memory storage from persistent
- // snapshot, state and entries.
- storage.ApplySnapshot(snapshot)
- storage.SetHardState(state)
- storage.Append(entries)
-
- c := &Config{
- ID: 0x01,
- ElectionTick: 10,
- HeartbeatTick: 1,
- Storage: storage,
- MaxSizePerMsg: 4096,
- MaxInflightMsgs: 256,
- }
-
- // restart raft without peer information.
- // peer information is already included in the storage.
- n := raft.RestartNode(c)
-
-Now that you are holding onto a Node you have a few responsibilities:
-
-First, you must read from the Node.Ready() channel and process the updates
-it contains. These steps may be performed in parallel, except as noted in step
-2.
-
-1. Write HardState, Entries, and Snapshot to persistent storage if they are
-not empty. Note that when writing an Entry with Index i, any
-previously-persisted entries with Index >= i must be discarded.
-
-2. Send all Messages to the nodes named in the To field. It is important that
-no messages be sent until the latest HardState has been persisted to disk,
-and all Entries written by any previous Ready batch (Messages may be sent while
-entries from the same batch are being persisted). To reduce the I/O latency, an
-optimization can be applied to make leader write to disk in parallel with its
-followers (as explained at section 10.2.1 in Raft thesis). If any Message has type
-MsgSnap, call Node.ReportSnapshot() after it has been sent (these messages may be
-large).
-
-Note: Marshalling messages is not thread-safe; it is important that you
-make sure that no new entries are persisted while marshalling.
-The easiest way to achieve this is to serialize the messages directly inside
-your main raft loop.
-
-3. Apply Snapshot (if any) and CommittedEntries to the state machine.
-If any committed Entry has Type EntryConfChange, call Node.ApplyConfChange()
-to apply it to the node. The configuration change may be cancelled at this point
-by setting the NodeID field to zero before calling ApplyConfChange
-(but ApplyConfChange must be called one way or the other, and the decision to cancel
-must be based solely on the state machine and not external information such as
-the observed health of the node).
-
-4. Call Node.Advance() to signal readiness for the next batch of updates.
-This may be done at any time after step 1, although all updates must be processed
-in the order they were returned by Ready.
-
-Second, all persisted log entries must be made available via an
-implementation of the Storage interface. The provided MemoryStorage
-type can be used for this (if you repopulate its state upon a
-restart), or you can supply your own disk-backed implementation.
-
-Third, when you receive a message from another node, pass it to Node.Step:
-
- func recvRaftRPC(ctx context.Context, m raftpb.Message) {
- n.Step(ctx, m)
- }
-
-Finally, you need to call Node.Tick() at regular intervals (probably
-via a time.Ticker). Raft has two important timeouts: heartbeat and the
-election timeout. However, internally to the raft package time is
-represented by an abstract "tick".
-
-The total state machine handling loop will look something like this:
-
- for {
- select {
- case <-s.Ticker:
- n.Tick()
- case rd := <-s.Node.Ready():
- saveToStorage(rd.State, rd.Entries, rd.Snapshot)
- send(rd.Messages)
- if !raft.IsEmptySnap(rd.Snapshot) {
- processSnapshot(rd.Snapshot)
- }
- for _, entry := range rd.CommittedEntries {
- process(entry)
- if entry.Type == raftpb.EntryConfChange {
- var cc raftpb.ConfChange
- cc.Unmarshal(entry.Data)
- s.Node.ApplyConfChange(cc)
- }
- }
- s.Node.Advance()
- case <-s.done:
- return
- }
- }
-
-To propose changes to the state machine from your node take your application
-data, serialize it into a byte slice and call:
-
- n.Propose(ctx, data)
-
-If the proposal is committed, data will appear in committed entries with type
-raftpb.EntryNormal. There is no guarantee that a proposed command will be
-committed; you may have to re-propose after a timeout.
-
-To add or remove a node in a cluster, build ConfChange struct 'cc' and call:
-
- n.ProposeConfChange(ctx, cc)
-
-After config change is committed, some committed entry with type
-raftpb.EntryConfChange will be returned. You must apply it to node through:
-
- var cc raftpb.ConfChange
- cc.Unmarshal(data)
- n.ApplyConfChange(cc)
-
-Note: An ID represents a unique node in a cluster for all time. A
-given ID MUST be used only once even if the old node has been removed.
-This means that for example IP addresses make poor node IDs since they
-may be reused. Node IDs must be non-zero.
-
-Implementation notes
-
-This implementation is up to date with the final Raft thesis
-(https://github.com/ongardie/dissertation/blob/master/stanford.pdf), although our
-implementation of the membership change protocol differs somewhat from
-that described in chapter 4. The key invariant that membership changes
-happen one node at a time is preserved, but in our implementation the
-membership change takes effect when its entry is applied, not when it
-is added to the log (so the entry is committed under the old
-membership instead of the new). This is equivalent in terms of safety,
-since the old and new configurations are guaranteed to overlap.
-
-To ensure that we do not attempt to commit two membership changes at
-once by matching log positions (which would be unsafe since they
-should have different quorum requirements), we simply disallow any
-proposed membership change while any uncommitted change appears in
-the leader's log.
-
-This approach introduces a problem when you try to remove a member
-from a two-member cluster: If one of the members dies before the
-other one receives the commit of the confchange entry, then the member
-cannot be removed any more since the cluster cannot make progress.
-For this reason it is highly recommended to use three or more nodes in
-every cluster.
-
-MessageType
-
-Package raft sends and receives message in Protocol Buffer format (defined
-in raftpb package). Each state (follower, candidate, leader) implements its
-own 'step' method ('stepFollower', 'stepCandidate', 'stepLeader') when
-advancing with the given raftpb.Message. Each step is determined by its
-raftpb.MessageType. Note that every step is checked by one common method
-'Step' that safety-checks the terms of node and incoming message to prevent
-stale log entries:
-
- 'MsgHup' is used for election. If a node is a follower or candidate, the
- 'tick' function in 'raft' struct is set as 'tickElection'. If a follower or
- candidate has not received any heartbeat before the election timeout, it
- passes 'MsgHup' to its Step method and becomes (or remains) a candidate to
- start a new election.
-
- 'MsgBeat' is an internal type that signals the leader to send a heartbeat of
- the 'MsgHeartbeat' type. If a node is a leader, the 'tick' function in
- the 'raft' struct is set as 'tickHeartbeat', and triggers the leader to
- send periodic 'MsgHeartbeat' messages to its followers.
-
- 'MsgProp' proposes to append data to its log entries. This is a special
- type to redirect proposals to leader. Therefore, send method overwrites
- raftpb.Message's term with its HardState's term to avoid attaching its
- local term to 'MsgProp'. When 'MsgProp' is passed to the leader's 'Step'
- method, the leader first calls the 'appendEntry' method to append entries
- to its log, and then calls 'bcastAppend' method to send those entries to
- its peers. When passed to candidate, 'MsgProp' is dropped. When passed to
- follower, 'MsgProp' is stored in follower's mailbox(msgs) by the send
- method. It is stored with sender's ID and later forwarded to leader by
- rafthttp package.
-
- 'MsgApp' contains log entries to replicate. A leader calls bcastAppend,
- which calls sendAppend, which sends soon-to-be-replicated logs in 'MsgApp'
- type. When 'MsgApp' is passed to candidate's Step method, candidate reverts
- back to follower, because it indicates that there is a valid leader sending
- 'MsgApp' messages. Candidate and follower respond to this message in
- 'MsgAppResp' type.
-
- 'MsgAppResp' is response to log replication request('MsgApp'). When
- 'MsgApp' is passed to candidate or follower's Step method, it responds by
- calling 'handleAppendEntries' method, which sends 'MsgAppResp' to raft
- mailbox.
-
- 'MsgVote' requests votes for election. When a node is a follower or
- candidate and 'MsgHup' is passed to its Step method, then the node calls
- 'campaign' method to campaign itself to become a leader. Once 'campaign'
- method is called, the node becomes candidate and sends 'MsgVote' to peers
- in cluster to request votes. When passed to leader or candidate's Step
- method and the message's Term is lower than leader's or candidate's,
- 'MsgVote' will be rejected ('MsgVoteResp' is returned with Reject true).
- If leader or candidate receives 'MsgVote' with higher term, it will revert
- back to follower. When 'MsgVote' is passed to follower, it votes for the
- sender only when sender's last term is greater than MsgVote's term or
- sender's last term is equal to MsgVote's term but sender's last committed
- index is greater than or equal to follower's.
-
- 'MsgVoteResp' contains responses from voting request. When 'MsgVoteResp' is
- passed to candidate, the candidate calculates how many votes it has won. If
- it's more than majority (quorum), it becomes leader and calls 'bcastAppend'.
- If candidate receives majority of votes of denials, it reverts back to
- follower.
-
- 'MsgPreVote' and 'MsgPreVoteResp' are used in an optional two-phase election
- protocol. When Config.PreVote is true, a pre-election is carried out first
- (using the same rules as a regular election), and no node increases its term
- number unless the pre-election indicates that the campaigning node would win.
- This minimizes disruption when a partitioned node rejoins the cluster.
-
- 'MsgSnap' requests to install a snapshot message. When a node has just
- become a leader or the leader receives 'MsgProp' message, it calls
- 'bcastAppend' method, which then calls 'sendAppend' method to each
- follower. In 'sendAppend', if a leader fails to get term or entries,
- the leader requests snapshot by sending 'MsgSnap' type message.
-
- 'MsgSnapStatus' tells the result of snapshot install message. When a
- follower rejected 'MsgSnap', it indicates the snapshot request with
- 'MsgSnap' had failed from network issues which causes the network layer
- to fail to send out snapshots to its followers. Then leader considers
- follower's progress as probe. When 'MsgSnap' were not rejected, it
- indicates that the snapshot succeeded and the leader sets follower's
- progress to probe and resumes its log replication.
-
- 'MsgHeartbeat' sends heartbeat from leader. When 'MsgHeartbeat' is passed
- to candidate and message's term is higher than candidate's, the candidate
- reverts back to follower and updates its committed index from the one in
- this heartbeat. And it sends the message to its mailbox. When
- 'MsgHeartbeat' is passed to follower's Step method and message's term is
- higher than follower's, the follower updates its leaderID with the ID
- from the message.
-
- 'MsgHeartbeatResp' is a response to 'MsgHeartbeat'. When 'MsgHeartbeatResp'
- is passed to leader's Step method, the leader knows which follower
- responded. And only when the leader's last committed index is greater than
- follower's Match index, the leader runs 'sendAppend` method.
-
- 'MsgUnreachable' tells that request(message) wasn't delivered. When
- 'MsgUnreachable' is passed to leader's Step method, the leader discovers
- that the follower that sent this 'MsgUnreachable' is not reachable, often
- indicating 'MsgApp' is lost. When follower's progress state is replicate,
- the leader sets it back to probe.

- // For example, consider a group in which id=1 is a learner and id=2 and

- // the quorum `{2,3}` without the config change being appended to the
- // learner's log. If the leader (say 2) fails, there are de facto two

- // all committed entries), but to do so it will need 1 to vote. But 1
- // considers itself a learner and will continue to do so until 3 has
- // stepped up as leader, replicates the conf change to 1, and 1 applies it.
- // Ultimately, by receiving a request to vote, the learner realizes that
- // the candidate believes it to be a voter, and that it should act
- // accordingly. The candidate's config may be stale, too; but in that case
- // it won't win the election, at least in the absence of the bug discussed

-// 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.

-Package wal provides an implementation of a write ahead log that is used by
-etcd.
-
-A WAL is created at a particular directory and is made up of a number of
-segmented WAL files. Inside of each file the raft state and entries are appended
-to it with the Save method:
-
- metadata := []byte{}
- w, err := wal.Create(zap.NewExample(), "/var/lib/etcd", metadata)
- ...
- err := w.Save(s, ents)
-
-After saving a raft snapshot to disk, SaveSnapshot method should be called to
-record it. So WAL can match with the saved snapshot when restarting.
-
- err := w.SaveSnapshot(walpb.Snapshot{Index: 10, Term: 2})
-
-When a user has finished using a WAL it must be closed:
-
- w.Close()
-
-Each WAL file is a stream of WAL records. A WAL record is a length field and a wal record
-protobuf. The record protobuf contains a CRC, a type, and a data payload. The length field is a
-64-bit packed structure holding the length of the remaining logical record data in its lower
-56 bits and its physical padding in the first three bits of the most significant byte. Each
-record is 8-byte aligned so that the length field is never torn. The CRC contains the CRC32
-value of all record protobufs preceding the current record.
-
-WAL files are placed inside of the directory in the following format:
-$seq-$index.wal
-
-The first WAL file to be created will be 0000000000000000-0000000000000000.wal
-indicating an initial sequence of 0 and an initial raft index of 0. The first
-entry written to WAL MUST have raft index 0.
-
-WAL will cut its current tail wal file if its size exceeds 64MB. This will increment an internal
-sequence number and cause a new file to be created. If the last raft index saved
-was 0x20 and this is the first time cut has been called on this WAL then the sequence will
-increment from 0x0 to 0x1. The new file will be: 0000000000000001-0000000000000021.wal.
-If a second cut issues 0x10 entries with incremental index later then the file will be called:
-0000000000000002-0000000000000031.wal.
-
-At a later time a WAL can be opened at a particular snapshot. If there is no
-snapshot, an empty snapshot should be passed in.
-
- w, err := wal.Open("/var/lib/etcd", walpb.Snapshot{Index: 10, Term: 2})
- ...
-
-The snapshot must have been written to the WAL.
-
-Additional items cannot be Saved to this WAL until all of the items from the given
-snapshot to the end of the WAL are read first:
-
- metadata, state, ents, err := w.ReadAll()
-
-This will give you the metadata, the last raft.State and the slice of
-raft.Entry items in the log.
