跑批调额系统说明文档

简介

业务想对贷后的人员贷款金额进行适当的调整，来优化贷后流程并且精准投放贷款给特定的人群。

流程主要包含四个部分：

数仓出数到 SFTP 系统
Spark 作业加载数据到 TIDB 表中
联机主任务和子任务处理数据库数据（该文档的核心工作）
贷后进行额度的审批调额（其他组的工作）

核心流程图：

post:http://localhost:8088/batchmaintask/putDatas

json 复制代码

{
    "taskId": "main_taskId_0",
    "inputCount": 100,
    "status": "INIT"
}

响应报文：

发起子任务功能

这个功能是由主任务调起的，但是方便测试，也可以单独调起。
