cherry-pick #36828 to branch-2.1 The requirement for predicate pushdown through the window operator is that the partition by slots of the window contains all slots in the predicate. The original implementation of doris only allows predicate pushdown with one slot. This PR relaxes this restriction and allows for predicate pushdown with multiple slots. The same applies to the predicate pushdown of the LogicalPartitionTopN operator. The following sql is an example. select * from ( select row_number() over(partition by id, value1 order by value1) as num, id, value1 from push_down_multi_column_predicate_through_window_t ) t where abs(id + value1)<4 and num <= 2; Co-authored-by: feiniaofeiafei <moailing@selectdb.com>
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 """
