21 . Tiered Storage •Infinite Stream: 以流的⽅式永远保存原始 数据 • 分区的容量不再受限 •充分利⽤云存储或者现有的廉价存储 （e.g.HDFS） •数据统⼀表征：客户端不需要关⼼数据究竟 存储在哪⾥
22 .Pulsar Functions
23 . 03 Go Client In Apache Pulasr
24 . CGO Is Not Go • Go 最初的定位（下⼀代的 C 语⾔） • 混合编程 （C && Go） • CGO 是⼀种⼯具，不是对 Go 语⾔的扩展 • 不⽀持交叉编译
25 . 性能损耗 • Go 的内存模型与 C 的不⼀致 • ⼤量的 runtime.cgocall() <go tool objdump> • 阻塞可能导致 M 的数量陡增 • 内存管理的⽅式不同
26 . 使⽤ CGO 的感悟 • ⼀定要严格控制边界 • 谨慎使⽤指针 • 注意类型转换 • 尽量减少 C 的调⽤ • 注意内存在哪⾥分配
