CurveBS I/O processing flow Before introducing IO processing flow, we first describe the overall architecture, data organization and topology structure of CURVE. CurveBS uses the central uses RAFT as a consistency protocol. The figure above is from the RAFT paper(https://raft.github.io/raft.pdf). CurveBS uses BRaft to implement the consistency protocol. For CurveBS 1. A CopySet curve-client, you only need to restart the NEBDServer, which affects services in few seconds. CurveBS IO processing flow Overall process The flow of user's read and write request to curve: 1.

I/O（Input/Output）基本概念 ▶ 数据源（Data Source） ▶ 数据宿（Data Sink） ▶ 流（Stream） Java 中把不同的数据源与程序间的数据传输都抽象表述为 流，java.io 包中定义了多种 I/O 流类型实现数据 I/O 功能。 大纲 Java I/O 原理 基础 I/O 流 常用 I/O 流类型 I/O 应用 Java I/O 流的分类 O 按照数据流动的方向 流可分为输入流（Input Stream）和输出流（Output Stream）。 ▶ 输入流只能从中读取数据，而不能向其写出数据； ▶ 输出流则只能向其写出数据，而不能从中读取数据。 ▶（特例 java.io.RandomAccessFile 类） 大纲 Java I/O 原理 基础 I/O 流 常用 I/O 流类型 I/O 应用 Java I/O 流的分类 O 根据数据流所关联的是数据源还是其他数据流 PrintStream BufferedOutputStream Object 大纲 Java I/O 原理 基础 I/O 流 常用 I/O 流类型 I/O 应用 InputStream 抽象类 java.io.InputStream 是所有字节输入流类型的父类，该 类中定义了以字节为单位读取数据的基本方法，并在其子类中进 行了分化和实现。 三个基本的 read 方法 ▶ int read() ▶ int
