this is brought by https://github.com/apache/doris/pull/33800 if mv is partitioned materialzied view, the data will be wrong by using the hited materialized view when the paritions in related base partiton table are deleted, created and so on. this fix the problem. if **SET enable_materialized_view_union_rewrite=true;** this will use the materializd view and make sure the data is corrent if **SET enable_materialized_view_union_rewrite=false;** this will query base table directly to make sure the data is right
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 """
