 The log printed by the Pipeline framework will carry both data_id and log_id. After auto-batching is turned on, the first `data_id` in the batch will be used to mark the whole batch, and the framework will print all data_ids in the batch in a log.

 ## 5.日志追踪
 Pipeline服务日志在当前目录的PipelineServingLogs目录下，有3种类型日志，分别是pipeline.log日志、pipeline.log.wf日志、pipeline.tracer日志。
-- pipeline.log日志 : 记录 debug & info日志信息
-- pipeline.log.wf日志 : 记录 warning & error日志
-- pipeline.tracer日志 : 统计各个阶段耗时、channel堆积信息
+- `pipeline.log` : 记录 debug & info日志信息
+- `pipeline.log.wf` : 记录 warning & error日志

 在服务发生异常时，错误信息会记录在pipeline.log.wf日志中。打印tracer日志要求在config.yml的DAG属性中添加tracer配置。
