新加case注意事项

  1. 变量名前要写 def,否则是全局变量,并行跑的 case 的时候可能被其他 case 影响。

    Problematic code:

    ret = ***
    

    Correct code:

    def ret = ***
    
  2. 尽量不要在 case 中 global 的设置 session variable,或者修改集群配置,可能会影响其他 case。

    Problematic code:

    sql """set global enable_pipeline_x_engine=true;"""
    

    Correct code:

    sql """set enable_pipeline_x_engine=true;"""
    
  3. 如果必须要设置 global,或者要改集群配置,可以指定 case 以 nonConcurrent 的方式运行。

    示例

  4. case 中涉及时间相关的,最好固定时间,不要用类似 now() 函数这种动态值,避免过一段时间后 case 就跑不过了。

    Problematic code:

    sql """select count(*) from table where created < now();"""
    

    Correct code:

    sql """select count(*) from table where created < '2023-11-13';"""
    
  5. case 中 streamload 后请加上 sync 一下,避免在多 FE 环境中执行不稳定。

    Problematic code:

    streamLoad { ... }
    sql """select count(*) from table """
    

    Correct code:

    streamLoad { ... }
    sql """sync"""
    sql """select count(*) from table """
