if create MTMV `date_trunc(`xxx`,'month')` when related table is `range` partition,and have 3 partitions: ``` 20200101-20200102 20200102-20200103 20200201-20200202 ``` then MTMV will have 2 partitions: ``` 20200101-20200201 20200201-20200301 ``` when related table is `list` partition,and have 3 partitions: ``` (20200101,20200102) (20200103) (20200201) ``` then MTMV will have 2 partitions: ``` (20200101,20200102,20200103) (20200201) ```
新加case注意事项
-
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 = *** -
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;""" -
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。
-
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';""" -
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 """
