Rob Day 959d004bcc docs: install etcdctl with `go get` as well 
The documentation recommends using `etcdctl` to verify that etcd has
been built correctly, but the `go get` command provided does not install
it. This changes it so that it does, and also clarifies terminology
('using `go get`', referring to the command used to install it, rather
than 'using `$GOPATH`').

raft: add (*RawNode).WithProgress
 2018-12-06 10:56:40 -08:00
Tobias Schottdorf bd332b318e raft: add (*RawNode).WithProgress 
Calls to Status can be frequent and currently incur three heap
allocations, but often the caller has no intention to hold on to the
returned status.

Add StatusWithoutProgress and WithProgress to allow avoiding heap
allocations altogether. StatusWithoutProgress does what's on the
tin and additionally returns a value (instead of a pointer) to
avoid the associated heap allocation. By not returning a Progress
map, it avoids all other allocations that Status incurs.

To still introspect the Progress map, add WithProgress, which
uses a simple visitor pattern.

Add benchmarks to verify that this is indeed allocation free.

docs/img: clarify "network partition + membership reconfiguration"
 2018-12-06 09:28:36 -08:00
Tobias Schottdorf bfaae1ba46 raft: enter ProgressStateReplica immediately after snapshot 
When a follower requires a snapshot and the snapshot is sent at the
committed (and last) index in an otherwise idle Raft group, the follower
would previously remain in ProgressStateProbe even though it had been
caught up completely.

In a busy Raft group this wouldn't be an issue since the next round of
MsgApp would update the state, but in an idle group there's nothing
that rectifies the status (since there's nothing to append or update).

The reason this matters is that the state is exposed through
`RaftStatus()`. Concretely, in CockroachDB, we use the Raft status to
make sharding decisions (since it's dangerous to make rapid changes
to a fragile Raft group), and had to work around this problem[1].
