About Bundler
gem install bundler installs the bundler gem through RubyGems. You only need to install it once - not every time you create a new Jekyll project. Here are some additional details:

分布式系统的常见数据场景：复制(Replication)、分区(Partitioning)和事务(Transactions) --《设计数据密集型应用》读书笔记
复制和分区是把数据分布在多台机器节点上的两种通用方式。其中，复制是把相同的数据复制一份放到多个不同的节点上（常常是物理上的不同地点），以数据冗余的方式提供系统的高可用（HA）和高性能；分区是把一个大的数据库拆分成一个个小的子集（叫partition），把它们分布到多个节点上。两者常常伴随一起使用。

Gossip协议
当你希望保证自己的系统在极端情况下（比如集群中只有一个节点在运行）的可用性，只需要实现最终一致性，可以通过 Gossip 协议实现这个目标。

一致性哈希算法
Raft 算法实现了 KV 存储，虽然领导者模型简化了算法实现和共识协商，但写请求只能限制在领导者节点上处理，导致了集群的接入性能约等于单机，那么随着业务发展，集群的性能可能就扛不住了，会造成系统过载和服务不可用，这时我们就要通过分集群，突破单集群的性能限制。
