Chaos
Chaos is used to check the distributed system linearizability.
Chaos is inspired by jepsen and uses porcupine as its linearizability checker.
Architecture
Chaos runs your registered database on 5 nodes, sends the command through ssh
to control the service, like starting/stoping the service, or using a nemesis to disturb the whole cluster.

| n1 | n2 | n3 | <+ +> | n4 | n5 |
+----+----+----+ +----+----+
Usage
In one shell, we start the 5 nodes and the controller.
cd docker
./up.sh
In another shell, use docker exec -it chaos-control bash
to enter the controller, then:
# build the node and your own chaos test
make
# run you own chaos like
./bin/chaos-tidb
Scaffold
It is very easy to write your own chaos test. TODO...
