 <ol>
-<li>A &quot;client-side&quot; approach in which message producers and consumers are responsible for not only serializing and deserializing messages (which consist of raw bytes) but also &quot;knowing&quot; which types are being transmitted via which topics. If a producer is sending temperature sensor data on the topic <code>topic-1</code>, consumers of that topic will run into trouble if they attempt to parse that data as, say, moisture sensor readings.</li>
-<li>A &quot;server-side&quot; approach in which producers and consumers inform the system which data types can be transmitted via the topic. With this approach, the messaging system enforces type safety and ensures that producers and consumers remain synced.</li>
+<li>&quot;客户端&quot; 方法, 消息生产者和消费者不仅负责序列化和反序列处理消息 (包括原始字节), 而且还 &quot;知道&quot; 哪些类型是通过哪些topic传输的。 如果生产者往主题 <code>topic-1</code>发送温度感应数据,而这个topic的consumer按照读取湿度感应的方式来转换数据,将会遇到问题。</li>
+<li>&quot;服务器端&quot; 方法, 生产者和消费者告知系统哪些数据类型可以通过topic传输。 通过这种方法,消息系统强制执行类型安全, 并确保生产者和消费者保持同步。</li>
 </ol>
-<p>Both approaches are available in Pulsar, and you're free to adopt one or the other or to mix and match on a per-topic basis.</p>
+<p>这两种方法都被Pulsar支持,你可以在topic的基础上,自由选择采用哪一种,或者混用。</p>
 <ol>
-<li>For the &quot;client-side&quot; approach, producers and consumers can send and receive messages consisting of raw byte arrays and leave all type safety enforcement to the application on an &quot;out-of-band&quot; basis.</li>
-<li>For the &quot;server-side&quot; approach, Pulsar has a built-in <strong>schema registry</strong> that enables clients to upload data schemas on a per-topic basis. Those schemas dictate which data types are recognized as valid for that topic.</li>
+<li>&quot;客户端&quot; 方法中, 生产者和消费者可以发送和接收由原始字节数组组成的消息, 并保留所有的类型安全在应用中,以“带外”基础上强制执行。</li>
+<li>&quot;服务器端&quot; 方法中,Pulsar有一个内置的 <strong>schema registry</strong>,它使客户端能够根据每个topic载入数据schema。 这些schema显示了,topic可以识别哪些数据类型为有效。</li>

 <ol>
-<li>A &quot;client-side&quot; approach in which message producers and consumers are responsible for not only serializing and deserializing messages (which consist of raw bytes) but also &quot;knowing&quot; which types are being transmitted via which topics. If a producer is sending temperature sensor data on the topic <code>topic-1</code>, consumers of that topic will run into trouble if they attempt to parse that data as, say, moisture sensor readings.</li>
-<li>A &quot;server-side&quot; approach in which producers and consumers inform the system which data types can be transmitted via the topic. With this approach, the messaging system enforces type safety and ensures that producers and consumers remain synced.</li>
+<li>&quot;客户端&quot; 方法, 消息生产者和消费者不仅负责序列化和反序列处理消息 (包括原始字节), 而且还 &quot;知道&quot; 哪些类型是通过哪些topic传输的。 如果生产者往主题 <code>topic-1</code>发送温度感应数据,而这个topic的consumer按照读取湿度感应的方式来转换数据,将会遇到问题。</li>
+<li>&quot;服务器端&quot; 方法, 生产者和消费者告知系统哪些数据类型可以通过topic传输。 通过这种方法,消息系统强制执行类型安全, 并确保生产者和消费者保持同步。</li>
 </ol>

 <ol>
-<li>For the &quot;client-side&quot; approach, producers and consumers can send and receive messages consisting of raw byte arrays and leave all type safety enforcement to the application on an &quot;out-of-band&quot; basis.</li>
-<li>For the &quot;server-side&quot; approach, Pulsar has a built-in <strong>schema registry</strong> that enables clients to upload data schemas on a per-topic basis. Those schemas dictate which data types are recognized as valid for that topic.</li>
+<li>&quot;客户端&quot; 方法中, 生产者和消费者可以发送和接收由原始字节数组组成的消息, 并保留所有的类型安全在应用中,以“带外”基础上强制执行。</li>

-<li>A <strong>name</strong>. In Pulsar, a schema's name is the topic to which the schema is applied.</li>
-<li>A <strong>payload</strong>, which is a binary representation of the schema</li>
-<li>A schema <a href="#supported-schema-formats"><strong>type</strong></a></li>
-<li>User-defined <strong>properties</strong> as a string/string map. Usage of properties is wholly application specific. Possible properties might be the Git hash associated with a schema, an environment like <code>dev</code> or <code>prod</code>, etc.</li>
+<li><strong>name</strong>。Pulsar中, schema的名称是schema应用于的topic。</li>
+<li>** payload **, 它是schema的二进制表示形式。</li>
+<li>Schema<a href="#supported-schema-formats"><strong>类型</strong></a></li>
+<li>用户定义的字符串/字符串映射map,** properties ** 。 Properties如何使用,完全由程序指定。 Properties可能是关联到schema的Git hash,例如<code>dev</code>或者<code>prod</code>等环境信息。</li>
 </ul>

+<p>Pulsar schema应用于<em>主题层面</em>(schema无法应用于namespace和tenant层面),并且被强制执行,producer和consumer上传schema到Pulsar broker。</p>
+<p>Pulsar schema是非常简单的数据结构,它的构成如下:</p>
 <ul>
-<li>A <strong>name</strong>. In Pulsar, a schema's name is the topic to which the schema is applied.</li>
-<li>A <strong>payload</strong>, which is a binary representation of the schema</li>
-<li>A schema <a href="#supported-schema-formats"><strong>type</strong></a></li>
-<li>User-defined <strong>properties</strong> as a string/string map. Usage of properties is wholly application specific. Possible properties might be the Git hash associated with a schema, an environment like <code>dev</code> or <code>prod</code>, etc.</li>
+<li><strong>name</strong>。Pulsar中, schema的名称是schema应用于的topic。</li>
+<li>** payload **, 它是schema的二进制表示形式。</li>
+<li>Schema<a href="#supported-schema-formats"><strong>类型</strong></a></li>
+<li>用户定义的字符串/字符串映射map,** properties ** 。 Properties如何使用,完全由程序指定。 Properties可能是关联到schema的Git hash,例如<code>dev</code>或者<code>prod</code>等环境信息。</li>

+<p>Pulsar schema应用于<em>主题层面</em>(schema无法应用于namespace和tenant层面),并且被强制执行,producer和consumer上传schema到Pulsar broker。</p>
+<p>Pulsar schema是非常简单的数据结构,它的构成如下:</p>
 <ul>
-<li>A <strong>name</strong>. In Pulsar, a schema's name is the topic to which the schema is applied.</li>
-<li>A <strong>payload</strong>, which is a binary representation of the schema</li>
-<li>A schema <a href="#supported-schema-formats"><strong>type</strong></a></li>
-<li>User-defined <strong>properties</strong> as a string/string map. Usage of properties is wholly application specific. Possible properties might be the Git hash associated with a schema, an environment like <code>dev</code> or <code>prod</code>, etc.</li>
+<li><strong>name</strong>。Pulsar中, schema的名称是schema应用于的topic。</li>
+<li>** payload **, 它是schema的二进制表示形式。</li>
+<li>Schema<a href="#supported-schema-formats"><strong>类型</strong></a></li>
+<li>用户定义的字符串/字符串映射map,** properties ** 。 Properties如何使用,完全由程序指定。 Properties可能是关联到schema的Git hash,例如<code>dev</code>或者<code>prod</code>等环境信息。</li>

+<p>租户和namespace是Pulsar支持多租户的两个关键概念。</p>

-<li>A namespace is the administrative unit nomenclature within a tenant. The configuration policies set on a namespace apply to all the topics created in that namespace. A tenant may create multiple namespaces via self-administration using the REST API and the <a href="/docs/zh-CN/next/pulsar-admin"><code>pulsar-admin</code></a> CLI tool. 例如,一个对接多个应用的租户,可以为每个应用创建不同的namespace。</li>
+<li>Pulsar为指定租户配置了适当的容量分配。</li>
+<li>Namespace是租户中管理单元的命名。 命名空间上设置的配置策略,适用于该命名空间中创建的所有主题。 租户可以通过自我管理,使用 REST API 和 <a href="/docs/zh-CN/next/pulsar-admin"><code>pulsar-admin</code></a> CLI 工具, 创建多个命名空间。 例如,一个对接多个应用的租户,可以为每个应用创建不同的namespace。</li>
 </ul>

 <ol>
-<li>A &quot;client-side&quot; approach in which message producers and consumers are responsible for not only serializing and deserializing messages (which consist of raw bytes) but also &quot;knowing&quot; which types are being transmitted via which topics. If a producer is sending temperature sensor data on the topic <code>topic-1</code>, consumers of that topic will run into trouble if they attempt to parse that data as, say, moisture sensor readings.</li>
-<li>A &quot;server-side&quot; approach in which producers and consumers inform the system which data types can be transmitted via the topic. With this approach, the messaging system enforces type safety and ensures that producers and consumers remain synced.</li>
+<li>&quot;客户端&quot; 方法, 消息生产者和消费者不仅负责序列化和反序列处理消息 (包括原始字节), 而且还 &quot;知道&quot; 哪些类型是通过哪些topic传输的。 如果生产者往主题 <code>topic-1</code>发送温度感应数据,而这个topic的consumer按照读取湿度感应的方式来转换数据,将会遇到问题。</li>
+<li>&quot;服务器端&quot; 方法, 生产者和消费者告知系统哪些数据类型可以通过topic传输。 通过这种方法,消息系统强制执行类型安全, 并确保生产者和消费者保持同步。</li>
 </ol>
-<p>Both approaches are available in Pulsar, and you're free to adopt one or the other or to mix and match on a per-topic basis.</p>
+<p>这两种方法都被Pulsar支持,你可以在topic的基础上,自由选择采用哪一种,或者混用。</p>
 <ol>
-<li>For the &quot;client-side&quot; approach, producers and consumers can send and receive messages consisting of raw byte arrays and leave all type safety enforcement to the application on an &quot;out-of-band&quot; basis.</li>
-<li>For the &quot;server-side&quot; approach, Pulsar has a built-in <strong>schema registry</strong> that enables clients to upload data schemas on a per-topic basis. Those schemas dictate which data types are recognized as valid for that topic.</li>
+<li>&quot;客户端&quot; 方法中, 生产者和消费者可以发送和接收由原始字节数组组成的消息, 并保留所有的类型安全在应用中,以“带外”基础上强制执行。</li>
+<li>&quot;服务器端&quot; 方法中,Pulsar有一个内置的 <strong>schema registry</strong>,它使客户端能够根据每个topic载入数据schema。 这些schema显示了,topic可以识别哪些数据类型为有效。</li>

 <ol>
-<li>A &quot;client-side&quot; approach in which message producers and consumers are responsible for not only serializing and deserializing messages (which consist of raw bytes) but also &quot;knowing&quot; which types are being transmitted via which topics. If a producer is sending temperature sensor data on the topic <code>topic-1</code>, consumers of that topic will run into trouble if they attempt to parse that data as, say, moisture sensor readings.</li>
-<li>A &quot;server-side&quot; approach in which producers and consumers inform the system which data types can be transmitted via the topic. With this approach, the messaging system enforces type safety and ensures that producers and consumers remain synced.</li>
+<li>&quot;客户端&quot; 方法, 消息生产者和消费者不仅负责序列化和反序列处理消息 (包括原始字节), 而且还 &quot;知道&quot; 哪些类型是通过哪些topic传输的。 如果生产者往主题 <code>topic-1</code>发送温度感应数据,而这个topic的consumer按照读取湿度感应的方式来转换数据,将会遇到问题。</li>
+<li>&quot;服务器端&quot; 方法, 生产者和消费者告知系统哪些数据类型可以通过topic传输。 通过这种方法,消息系统强制执行类型安全, 并确保生产者和消费者保持同步。</li>
 </ol>
-<p>Both approaches are available in Pulsar, and you're free to adopt one or the other or to mix and match on a per-topic basis.</p>
+<p>这两种方法都被Pulsar支持,你可以在topic的基础上,自由选择采用哪一种,或者混用。</p>
 <ol>
-<li>For the &quot;client-side&quot; approach, producers and consumers can send and receive messages consisting of raw byte arrays and leave all type safety enforcement to the application on an &quot;out-of-band&quot; basis.</li>
-<li>For the &quot;server-side&quot; approach, Pulsar has a built-in <strong>schema registry</strong> that enables clients to upload data schemas on a per-topic basis. Those schemas dictate which data types are recognized as valid for that topic.</li>
+<li>&quot;客户端&quot; 方法中, 生产者和消费者可以发送和接收由原始字节数组组成的消息, 并保留所有的类型安全在应用中,以“带外”基础上强制执行。</li>
+<li>&quot;服务器端&quot; 方法中,Pulsar有一个内置的 <strong>schema registry</strong>,它使客户端能够根据每个topic载入数据schema。 这些schema显示了,topic可以识别哪些数据类型为有效。</li>
