<p>基本概念</p>
|
||
<ul>
|
||
<li>bucket – 类比于文件系统的目录</li>
|
||
<li>Object – 类比文件系统的文件</li>
|
||
<li>Keys – 类比文件名</li>

||
<h2 id="2-特点"><a href="#2-特点" class="headerlink" title="2.特点"></a>2.特点</h2><ul>
|
||
<li><p>数据保护</p>
|
||
<p>Minio使用Minio Erasure Code（纠删码）来防止硬件故障。即便损坏一半以上的driver，但是仍然可以从中恢复。</p>
|
||
</li>
|
||
<li><p>高性能</p>
|
||
<p>作为高性能对象存储，在标准硬件条件下它能达到55GB/s的读、35GB/s的写速率</p>
|
||
</li>
|
||
<li><p>可扩容</p>
|
||
<p>不同MinIO集群可以组成联邦，并形成一个全局的命名空间，并跨越多个数据中心</p>
|
||
</li>
|
||
<li><p>SDK支持</p>
|
||
<p>基于Minio轻量的特点，它得到类似Java、Python或Go等语言的sdk支持</p>
|
||
</li>
|
||
<li><p>有操作页面</p>
|
||
<p>面向用户友好的简单操作界面，非常方便的管理Bucket及里面的文件资源</p>
|
||
</li>
|
||
<li><p>功能简单</p>
|
||
<p>这一设计原则让MinIO不容易出错、更快启动</p>
|
||
</li>
|
||
<li><p>丰富的API</p>
|
||
<p>支持文件资源的分享连接及分享链接的过期策略、存储桶操作、文件列表访问及文件上传下载的基本功能等。</p>
|
||
</li>
|
||
<li><p>文件变化主动通知</p>
|
||
<p>存储桶（Bucket）如果发生改变,比如上传对象和删除对象，可以使用存储桶事件通知机制进行监控，并通过以下方式发布出去:AMQP、MQTT、Elasticsearch、Redis、NATS、MySQL、Kafka、Webhooks等。</p>
