   - 在数据流的不同处理阶段可以引用不同类型的Pipelines，所有Pipelines(一系列Functions组成)架构和内部结构一致，只分为Projection和Aggregate两种类型。按Pipeline所在数据流的位置可分为：
-    - **Pre-processing Pipelines ：，可选，**前处理数据管道对输入日志进行格式化或执行一系列全局处理函数（例如：从原始日志中提取感兴趣的字段）。

     - **Post-processing Pipelines ，可选，**后处理数据管道，发送到目的地之前对日志进行格式化或执行一系列全局处理函数（例如：对输出的日志进行格式验证、类型转换）
   - 数据流处理基本单元为处理器，按功能分为无状态和有状态处理器。每个处理器可以连接多个函数，组成一个Pipeline。

+### UUID
 
+Generate a version 4 (random) UUID in accordance with [RFC-9562](https://datatracker.ietf.org/doc/rfc9562/).
+
+```UUID(output_fields)```
+- filter: not required
+- lookup_fields: not required
+- output_fields: required
+- parameters: not required
+
+Example:
+
+```yaml
+- function: UUID
+  output_fields: [uuid]
+```
+Result: such as 3f0f8d7e-d89e-4b0a-9f2e-2eab5c99d062.
+
+### UUIDv5
+
+Generate a version 5 (namespaced) UUID in accordance with RFC-9562 for the given name and namespace. If namespace is not a valid UUID, this function will fail.
+Suitable for consistent identifiers across different systems. One of IP, DOMAIN, APP, or SUBSCRIBER to use a predefined namespace. 
+- NAMESPACE_IP: `6ba7b890-9dad-11d1-80b4-00c04fd430c8`

+### UUIDv7
+
+Generate a version 7 (Unix-timestamp + random based variant) UUID in accordance with RFC-9562. Suitable for scenarios that require time ordering, such as database indexing and logging.
