-## 13. Lambda Expression
-
-### 13.1 JEXL Function
-
-Java Expression Language (JEXL) is an expression language engine. We use JEXL to extend UDFs, which are implemented on the command line with simple lambda expressions. See the link for [operators supported in jexl lambda expressions](https://commons.apache.org/proper/commons-jexl/apidocs/org/apache/commons/jexl3/package-summary.html#customization).

-| JEXL   | INT32 / INT64 / FLOAT / DOUBLE / TEXT / BOOLEAN | `expr` is a lambda expression that supports standard one or multi arguments in the form `x -> {...}` or `(x, y, z) -> {...}`, e.g. ` x -> {x * 2}`, `(x, y, z) -> {x + y * z}` | INT32 / INT64 / FLOAT / DOUBLE / TEXT / BOOLEAN | Returns the input time series transformed by a lambda expression |

-
-### 13.1 JEXL 自定义函数
-
-#### 函数简介
-
-Java Expression Language (JEXL) 是一个表达式语言引擎。我们使用 JEXL 来扩展 UDF，在命令行中，通过简易的 lambda 表达式来实现 UDF。
-
-lambda 表达式中支持的运算符详见链接 [JEXL 中 lambda 表达式支持的运算符](https://commons.apache.org/proper/commons-jexl/apidocs/org/apache/commons/jexl3/package-summary.html#customization) 。
-
-| 函数名      | 可接收的输入序列类型                     | 必要的属性参数                               | 输出序列类型     | 功能类型                                             |
-|----------|--------------------------------|---------------------------------------|------------|--------------------------------------------------|
-| JEXL   | INT32 / INT64 / FLOAT / DOUBLE / TEXT / BOOLEAN | `expr`是一个支持标准的一元或多元参数的lambda表达式，符合`x -> {...}`或`(x, y, z) -> {...}`的格式，例如`x -> {x * 2}`, `(x, y, z) -> {x + y * z}`| INT32 / INT64 / FLOAT / DOUBLE / TEXT / BOOLEAN | 返回将输入的时间序列通过lambda表达式变换的序列             |

-## Lambda 表达式
-
-### JEXL 自定义函数
-
-#### 函数简介
-
-Java Expression Language (JEXL) 是一个表达式语言引擎。我们使用 JEXL 来扩展 UDF，在命令行中，通过简易的 lambda 表达式来实现 UDF。
-
-lambda 表达式中支持的运算符详见链接 [JEXL 中 lambda 表达式支持的运算符](https://commons.apache.org/proper/commons-jexl/apidocs/org/apache/commons/jexl3/package-summary.html#customization) 。
-
-| 函数名      | 可接收的输入序列类型                     | 必要的属性参数                               | 输出序列类型     | 功能类型                                             |
-|----------|--------------------------------|---------------------------------------|------------|--------------------------------------------------|
-| JEXL   | INT32 / INT64 / FLOAT / DOUBLE / TEXT / BOOLEAN | `expr`是一个支持标准的一元或多元参数的lambda表达式，符合`x -> {...}`或`(x, y, z) -> {...}`的格式，例如`x -> {x * 2}`, `(x, y, z) -> {x + y * z}`| INT32 / INT64 / FLOAT / DOUBLE / TEXT / BOOLEAN | 返回将输入的时间序列通过lambda表达式变换的序列             |
