  1. 案例-SDD的由来和设计 蓝金伟(lanjinwei@gmail.com)

  2. 通读 Dynamo 论文 • Dynamo: Amazon’s Highly Available Key-value Store • Amazon主要强调了 dynamo的高可用

  3. 核心数据结构 • Ring(环状结构)

  4. 技术要点 • 一致性hash • 向量时钟 • 故障处理 • 节点维护

  5. SDD的设计图 • 基本参照 dynamo 的思想

  6. SDD的实现 • C++ • NRW=322 • MC协议 • MCDB • Gossip协议 • 一致性hash • Membership • Bdb • 历时2个月

  7. SDD的问题 • 应用方认为太浪费了,因为SDD采用1式三份的机制 • 应用方认为运维工具不够成熟,需要完善 • 应用方认为性能没有mc,mcdb高
