末蓝、 2023-02-22 12:30 27阅读 0赞

Apache DolphinScheduler 是一个分布式去中心化，易扩展的可视化 DAG 工作流任务调度系统。致力于解决数据处理流程中错综复杂的依赖关系，使调度系统在数据处理流程中开箱即用。

近日，伯毅同学给社区贡献了工作流核心表结构的剖析文章，非常细致，喜欢的伙伴请转走

# 1. 工作流总体存储结构 #

在 dolphinscheduler 库中创建的所有工作流定义(模板)都保存在 t\_ds\_process\_definition 表中.

该数据库表结构如下表所示:

<table> 
 <thead> 
  <tr> 
   <th>序号</th> 
   <th>字段</th> 
   <th>类型</th> 
   <th>描述</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>1</td> 
   <td>id</td> 
   <td>int(11)</td> 
   <td>主键</td> 
  </tr> 
  <tr> 
   <td>2</td> 
   <td>name</td> 
   <td>varchar(255)</td> 
   <td>流程定义名称</td> 
  </tr> 
  <tr> 
   <td>3</td> 
   <td>version</td> 
   <td>int(11)</td> 
   <td>流程定义版本</td> 
  </tr> 
  <tr> 
   <td>4</td> 
   <td>release_state</td> 
   <td>tinyint(4)</td> 
   <td>流程定义的发布状态：0 未上线 , 1已上线</td> 
  </tr> 
  <tr> 
   <td>5</td> 
   <td>project_id</td> 
   <td>int(11)</td> 
   <td>项目id</td> 
  </tr> 
  <tr> 
   <td>6</td> 
   <td>user_id</td> 
   <td>int(11)</td> 
   <td>流程定义所属用户id</td> 
  </tr> 
  <tr> 
   <td>7</td> 
   <td>process_definition_json</td> 
   <td>longtext</td> 
   <td>流程定义JSON</td> 
  </tr> 
  <tr> 
   <td>8</td> 
   <td>description</td> 
   <td>text</td> 
   <td>流程定义描述</td> 
  </tr> 
  <tr> 
   <td>9</td> 
   <td>global_params</td> 
   <td>text</td> 
   <td>全局参数</td> 
  </tr> 
  <tr> 
   <td>10</td> 
   <td>flag</td> 
   <td>tinyint(4)</td> 
   <td>流程是否可用：0 不可用，1 可用</td> 
  </tr> 
  <tr> 
   <td>11</td> 
   <td>locations</td> 
   <td>text</td> 
   <td>节点坐标信息</td> 
  </tr> 
  <tr> 
   <td>12</td> 
   <td>connects</td> 
   <td>text</td> 
   <td>节点连线信息</td> 
  </tr> 
  <tr> 
   <td>13</td> 
   <td>receivers</td> 
   <td>text</td> 
   <td>收件人</td> 
  </tr> 
  <tr> 
   <td>14</td> 
   <td>receivers_cc</td> 
   <td>text</td> 
   <td>抄送人</td> 
  </tr> 
  <tr> 
   <td>15</td> 
   <td>create_time</td> 
   <td>datetime</td> 
   <td>创建时间</td> 
  </tr> 
  <tr> 
   <td>16</td> 
   <td>timeout</td> 
   <td>int(11)</td> 
   <td>超时时间</td> 
  </tr> 
  <tr> 
   <td>17</td> 
   <td>tenant_id</td> 
   <td>int(11)</td> 
   <td>租户id</td> 
  </tr> 
  <tr> 
   <td>18</td> 
   <td>update_time</td> 
   <td>datetime</td> 
   <td>更新时间</td> 
  </tr> 
  <tr> 
   <td>19</td> 
   <td>modify_by</td> 
   <td>varchar(36)</td> 
   <td>修改用户</td> 
  </tr> 
  <tr> 
   <td>20</td> 
   <td>resource_ids</td> 
   <td>varchar(255)</td> 
   <td>资源ids</td> 
  </tr> 
 </tbody> 
</table>

其中 process\_definition\_json 字段为核心字段, 定义了 DAG 图中的任务信息.该数据以JSON 的方式进行存储.

公共的数据结构如下表:

<table> 
 <thead> 
  <tr> 
   <th>序号</th> 
   <th>字段</th> 
   <th>类型</th> 
   <th>描述</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>1</td> 
   <td>globalParams</td> 
   <td>Array</td> 
   <td>全局参数</td> 
  </tr> 
  <tr> 
   <td>2</td> 
   <td>tasks</td> 
   <td>Array</td> 
   <td>流程中的任务集合 [ 各个类型的结构请参考如下章节]</td> 
  </tr> 
  <tr> 
   <td>3</td> 
   <td>tenantId</td> 
   <td>int</td> 
   <td>租户id</td> 
  </tr> 
  <tr> 
   <td>4</td> 
   <td>timeout</td> 
   <td>int</td> 
   <td>超时时间</td> 
  </tr> 
 </tbody> 
</table>

数据示例:

{ 
        "globalParams":[
            { 
                "prop":"golbal_bizdate",
                "direct":"IN",
                "type":"VARCHAR",
                "value":"${system.biz.date}"
            }
        ],
        "tasks":Array[1],
        "tenantId":0,
        "timeout":0
    }

### Apache DolphinScheduler四大特性 ###

![file][file 3]

### Apache DolphinScheduler 能力: ###

*  以DAG图的方式将Task按照任务的依赖关系关联起来，可实时可视化监控任务的运行状态
 *  支持丰富的任务类型：Shell、MR、Spark、Flink、SQL(mysql、postgresql、hive、sparksql)、Python、Http、Sub\_Process、Procedure等
 *  支持工作流定时调度、依赖调度、手动调度、手动暂停/停止/恢复，同时支持失败重试/告警、从指定节点恢复失败、Kill任务等操作
 *  支持工作流优先级、任务优先级及任务的故障转移及任务超时告警/失败
 *  支持工作流全局参数及节点自定义参数设置
 *  支持资源文件的在线上传/下载，管理等，支持在线文件创建、编辑
 *  支持任务日志在线查看及滚动、在线下载日志等
 *  实现集群HA，通过Zookeeper实现Master集群和Worker集群去中心化
 *  支持对Master/Worker cpu load，memory，cpu在线查看
 *  支持工作流运行历史树形/甘特图展示、支持任务状态统计、流程状态统计
 *  支持补数
 *  支持多租户
 *  支持国际化

### Apache DolphinScheduler 1.3 新特性 ###

* Worker实现重构，提升Worker性能
    
    * Master和Worker引入Netty通信
    
    * 去zookeeper任务队列
    
    * Worker节点的三种选择：随机、循环和CPU和内存的线性加权负载平衡
    
    * Worker去数据库操作
    
    * 资源中心支持多目录
    
    * 添加 if/else 条件任务
    
    * 添加 sqoop/datax 任务
    
    * 支持 k8s 部署
    
    * 添加DAG流程图一键格式化
    
    * 流程图美化
    
    * 支持 ambari 插件安装
    
    * 批量导出和导入工作流
    
    * 流程定义支持复制
    
    * 大幅简化配置项，简化部署
