It supports +fully serializable transactions, ACID semantics, and lock-free MVCC with +multiple readers and a single writer. Bolt can be used for projects that +want a simple data store without the need to add large dependencies such as +Postgres or MySQL. + +Bolt is a single-level, zero-copy, B+tree data store. This means that Bolt is +optimized for fast read access and does not require recovery in the event of a +system crash. Transactions which have not finished committing will simply be +rolled back in the event of a crash. + +The design of Bolt is based on Howard Chu's LMDB database project. + +Bolt currently works on Windows, Mac OS X, and Linux. + + +Basics + +There are only a few types in Bolt: DB, Bucket, Tx, and Cursor. The DB is +a collection of buckets and is represented by a single file on disk. A bucket is +a collection of unique keys that are associated with values. + +Transactions provide either read-only or read-write access to the database. +Read-only transactions can retrieve key/value pairs and can use Cursors to +iterate over the dataset sequentially. Read-write transactions can create and +delete buckets and can insert and remove keys. Only one read-write transaction +is allowed at a time. + + +Caveats + +The database uses a read-only, memory-mapped data file to ensure that +applications cannot corrupt the database, however, this means that keys and +values returned from Bolt cannot be changed. Writing to a read-only byte slice +will cause Go to panic. + +Keys and values retrieved from the database are only valid for the life of +the transaction. When used outside the transaction, these byte slices can +point to different data or can point to invalid memory which will cause a panic. + + +*/ +package bbolt diff --git

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 serialise 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 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://ramcloud.stanford.edu/~ongaro/thesis.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 campaigining 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. + +*/ +package raft diff --git a/vendor/github.com/coreos/etcd/raft/log.go b/vendor/github.com/coreos/etcd/raft/log.go new file mode 100644 index 00000000000..c3036d3c90d --- /dev/null +++ b/vendor/github.com/coreos/etcd/raft/log.go @@ -0,0 +1,358 @@ +// Copyright 2015 The etcd Authors +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +package raft + +import ( + "fmt" + "log" + + pb "github.com/coreos/etcd/raft/raftpb" +) + +type raftLog struct { + // storage contains all stable entries since the last snapshot. + storage Storage + + // unstable contains all unstable entries and snapshot. + // they will be saved into storage. + unstable unstable + + // committed is the highest log position that is known to be in + // stable storage on a quorum of nodes. + committed uint64 + // applied is the highest log position that the application has + // been instructed to apply to its state machine. + // Invariant: applied <= committed + applied uint64 + + logger Logger +} + +// newLog returns log using the given storage.

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 serialise 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 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://ramcloud.stanford.edu/~ongaro/thesis.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 campaigining 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. + +*/ +package raft diff --git a/vendor/go.etcd.io/etcd/raft/log.go b/vendor/go.etcd.io/etcd/raft/log.go new file mode 100644 index 00000000000..c3036d3c90d --- /dev/null +++ b/vendor/go.etcd.io/etcd/raft/log.go @@ -0,0 +1,358 @@ +// Copyright 2015 The etcd Authors +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +package raft + +import ( + "fmt" + "log" + + pb "github.com/coreos/etcd/raft/raftpb" +) + +type raftLog struct { + // storage contains all stable entries since the last snapshot. + storage Storage + + // unstable contains all unstable entries and snapshot. + // they will be saved into storage. + unstable unstable + + // committed is the highest log position that is known to be in + // stable storage on a quorum of nodes. + committed uint64 + // applied is the highest log position that the application has + // been instructed to apply to its state machine. + // Invariant: applied <= committed + applied uint64 + + logger Logger +} + +// newLog returns log using the given storage.

Each +record is 8-byte aligned so that the length field is never torn.
