In NormalizeRepeat, three parts of the outputExpression of LogicalRepeat need to be pushed down and outputted by bottom project: flattenGroupingSetExpr, argumentsOfGroupingScalarFunction, argumentsOfAggregateFunction. In the original code, use these three parts to rewrite the outputExpressions of LogicalRepeat to slots.This can cause problems in some cases, for example: ```sql SELECT ROUND( SUM(pk + 1) - 3) col_alias1, pk + 1 AS col_alias3 FROM table_20_undef_partitions2_keys3_properties4_distributed_by53 GROUP BY GROUPING SETS ((pk), ()) ; ``` The three parts expression needed to be pushed down are: pk, pk+1. The original code use pk+1 to rewrite the pk + 1 AS col_alias3 to slot. But the pk+1 is not in the list of grouping outputs, and then report error. This pr change the rewrite process, divide the expression needed to be pushed down into 2 parts: one is (flattenGroupingSetExpr) and the other one is (argumentsOfGroupingScalarFunction, argumentsOfAggregateFunction). and use the flattenGroupingSetExpr rewrite all LogicalRepeat outputExpressions, and use the argumentsOfGroupingScalarFunction, argumentsOfAggregateFunction to rewrite only the agg function arguments and the grouping scalar function. So, in the above sql, the pk + 1 AS col_alias3 will not be rewritten to slot, and can be computed.
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 """
