测试librdkafka

1. 版本匹配问题
2. 重新编译0.8版本
3. 进入tests目录
4. 运行example

1 版本匹配问题

经过尝试，librdkafka 0.9 不向前兼容kafka 0.8.1, 因此，当使用kafka0.8.1 server的时候，需要使用对应的librdkafka版本。

2 重新编译0.8版本

首先切换到librdkafka代码的0.8 branch 然后重新编译代码

make clean./configuremake

3 进入tests目录

运行下面的命令进行测试，可以看到测试全部通过。

4 运行example

前面已经在test topic中写入了消息，这里需要读取出来 -p 0 指的是partition 0

[dean@dell_xps_13 examples]$ ./rdkafka_example_cpp -C -t test -p 0% Created consumer rdkafka#consumer-0Read msg at offset 0hello, world

也可以对多个broker读取信息，并且采用ccb的方式，ccb指的是consumber call back，据说这个性能更高。

./rdkafka_example_cpp -C -t test -p 0 -b localhost:9093,localhost:9094,localhost:9095 -f ccb

你好！这是你第一次使用 **Markdown编辑器** 所展示的欢迎页。如果你想学习如何使用Markdown编辑器, 可以仔细阅读这篇文章，了解一下Markdown的基本语法知识。

新的改变

我们对Markdown编辑器进行了一些功能拓展与语法支持，除了标准的Markdown编辑器功能，我们增加了如下几点新功能，帮助你用它写博客：

全新的界面设计 ，将会带来全新的写作体验；
在创作中心设置你喜爱的代码高亮样式，Markdown 将代码片显示选择的高亮样式 进行展示；
增加了 图片拖拽 功能，你可以将本地的图片直接拖拽到编辑区域直接展示；
全新的 KaTeX数学公式 语法；
增加了支持甘特图的mermaid语法¹ 功能；
增加了 多屏幕编辑 Markdown文章功能；
增加了 焦点写作模式、预览模式、简洁写作模式、左右区域同步滚轮设置 等功能，功能按钮位于编辑区域与预览区域中间；
增加了 检查列表 功能。

功能快捷键

撤销：Ctrl/Command + Z
重做：Ctrl/Command + Y
加粗：Ctrl/Command + B
斜体：Ctrl/Command + I
标题：Ctrl/Command + Shift + H
无序列表：Ctrl/Command + Shift + U
有序列表：Ctrl/Command + Shift + O
检查列表：Ctrl/Command + Shift + C
插入代码：Ctrl/Command + Shift + K
插入链接：Ctrl/Command + Shift + L
插入图片：Ctrl/Command + Shift + G

合理的创建标题，有助于目录的生成

直接输入1次#，并按下space后，将生成1级标题。
输入2次#，并按下space后，将生成2级标题。
以此类推，我们支持6级标题。有助于使用TOC语法后生成一个完美的目录。

如何改变文本的样式

强调文本 强调文本

加粗文本 加粗文本

标记文本

删除文本

引用文本

H₂O is是液体。

2¹⁰ 运算结果是 1024.

插入链接与图片

链接: link.

带尺寸的图片:

当然，我们为了让用户更加便捷，我们增加了图片拖拽功能。

如何插入一段漂亮的代码片

去博客设置页面，选择一款你喜欢的代码片高亮样式，下面展示同样高亮的 代码片.

// An highlighted block var foo = 'bar';

生成一个适合你的列表

创建一个表格

一个简单的表格是这么创建的：

项目	Value
电脑	$1600
手机	$12
导管	$1

设定内容居中、居左、居右

使用:---------:居中
使用:----------居左
使用----------:居右

第一列	第二列	第三列
第一列文本居中	第二列文本居右	第三列文本居左

SmartyPants

SmartyPants将ASCII标点字符转换为“智能”印刷标点HTML实体。例如：

TYPE	ASCII	HTML
Single backticks	`'Isn't this fun?'`	‘Isn’t this fun?’
Quotes	`"Isn't this fun?"`	“Isn’t this fun?”
Dashes	`-- is en-dash, --- is em-dash`	– is en-dash, — is em-dash

创建一个自定义列表

Markdown: Text-to-HTML conversion tool

如何创建一个注脚

一个具有注脚的文本。²

注释也是必不可少的

Markdown将文本转换为 HTML。

KaTeX数学公式

您可以使用渲染LaTeX数学表达式 KaTeX:

Gamma公式展示 Γ(n)=(n−1)!∀n∈N\Gamma(n) = (n-1)!\quad\forall n\in\mathbb NΓ(n)=(n−1)!∀n∈N 是通过欧拉积分

Γ(z)=∫0∞tz−1e−tdt .\Gamma(z) = \int_0^\infty t^{z-1}e^{-t}dt\,. Γ(z)=∫0∞tz−1e−tdt.

新的甘特图功能，丰富你的文章

ganttdateFormat  YYYY-MM-DDtitle Adding GANTT diagram functionality to mermaidsection 现有任务已完成               :done,    des1, 2014-01-06,2014-01-08进行中               :active,  des2, 2014-01-09, 3d计划一               :         des3, after des2, 5d计划二               :         des4, after des3, 5d

关于 甘特图 语法，参考这儿,

UML 图表

可以使用UML图表进行渲染。 Mermaid. 例如下面产生的一个序列图：:

张三李四王五你好！李四, 最近怎么样?你最近怎么样，王五？我很好，谢谢!我很好，谢谢!李四想了很长时间,文字太长了不适合放在一行.打量着王五...很好... 王五, 你怎么样?张三李四王五

这将产生一个流程图。:

链接

长方形

圆

圆角长方形

菱形

关于 Mermaid 语法，参考这儿,

FLowchart流程图

我们依旧会支持flowchart的流程图：
