+模块让用户能够对 Flink 内置对象进行扩展。例如，通过自定义函数扩展内置函数，这些自定义函数和内置函数没有区别。模块是可插拔的，Flink
已经提供了一些预构建的模块，用户还可以实现自己的模块。
-Modules allow users to extend Flink's built-in objects, such as defining
functions that behave like Flink
-built-in functions. They are pluggable, and while Flink provides a few
pre-built modules, users can write
-their own.
-
-For example, users can define their own geo functions and plug them into Flink
as built-in functions to be used in
-Flink SQL and Table APIs. Another example is users can load an out-of-shelf
Hive module to use Hive built-in
-functions as Flink built-in functions.
+例如，用户可以自定义 geo 函数，并将其作为内置函数插入 Flink，随后就可以在 Flink SQL 和 Table API
中使用它了。另一个示例是，用户可以加载现成的 Hive 模块，随后就可以像使用 Flink 内置函数一样使用 Hive 模块的函数了。

-## Module Types
+## 模块类型
+
+### 核心模块
-### CoreModule
+`CoreModule` 包含 Flink 的所有内置函数，默认加载。
-`CoreModule` contains all of Flink's system (built-in) functions and is loaded
by default.
+### Hive 模块
-### HiveModule
+ `HiveModule` 为 Flink SQL 和 Table API 的用户提供了Hive 内置函数，它们类似于 Flink 内置函数。 [Hive
文档]({{ site.baseurl }}/zh/dev/table/hive/hive_functions.html) 提供了设置该模块的详细方法。
-The `HiveModule` provides Hive built-in functions as Flink's system functions
to SQL and Table API users.
-Flink's [Hive documentation]({{ site.baseurl
}}/dev/table/hive/hive_functions.html) provides full details on setting up the
module.
+### 自定义模块
-### User-Defined Module
+用户可以通过实现 `Module` 接口来开发自定义模块。为了能在 SQL CLI 使用，用户还需要通过实现 `ModuleFactory`
接口来为对应的模块开发一个模块工厂。
-Users can develop custom modules by implementing the `Module` interface.
-To use custom modules in SQL CLI, users should develop both a module and its
corresponding module factory by implementing
-the `ModuleFactory` interface.
+模块工厂定义了一组属性，用于在 SQL CLI 启动时配置模块。属性会传递给发现服务，发现服务会使用与属性相匹配的模块工厂来创建模块实例。
