集群基本概念(概念本身和AKKA特有的概念，成员状态，集群演示)

Cluster API Extension:Joining and Leaving a Cluster,Cluster Subscriptions,Cluster State Cluster Membership API: Joining,Leaving,Downing Node Roles: Failure Detector: Test Configuration: Higher level Cluster tools:Cluster Singleton,Cluster Sharding,Distributed Data,Distributed Publish Subscribe,Cluster aware routers ,Cluster across multiple data centers,Reliable Delivery

集群功能与模块（带演示集群状态变更和脑裂/集群案例）

Cluster Sharding:ShardCoordinator,Message,ShardRegion,Shard,Entity

Distributed Publish Subscribe:

集群设计与实现

Akka Cluster provides a fault-tolerant decentralized peer-to-peer based Cluster Membership Service with no single point of failure or single point of bottleneck. It does this using gossip protocols and an automatic failure detector.

集群其它技术

和分布式的区别（stateless vs stateful）

和服务注册发现区别

去中心化和中心化区别是什么？通信协议(gossip)，节点职责？

membership change:raft是配置,akka cluster是节点。

membership（每个人知道全部节点）

availability：membership,distributed data,PubSub，Multi-DC consistency: singletons,sharding,lease

Classic Cluster和Typed Cluster的区别

Reliable delivery

脑裂: sh akka cluster start

sh akka node stop 9

sh akka node down 8
