name: dm_sharding_pessimistic_add_column
features: [dm]
summary: 测试悲观模式合库合表
steps: |
    1. 使用dmctl operate create source.yaml添加source
    2. 使用dmctl task-start task.yaml with with online-ddl=true, is-sharding=true, shard-mode=pessimistic
    3. 在增量数据导入的时候之前分别执行alter table add column, 之后继续导入数据
    4. check downstream status and analyse the speed.
expectedResult: |
    步骤1. 创建source成功
    步骤2. 创建悲观合库合表任务成功
    步骤3. 使用dmctl query-status task-name查看任务
    步骤4. 5min之后，上下游对比一致
