Add aggregate materializedviewRules for query rewrite.
it support the query rewrite as following:
def mv = "select lineitem.L_LINENUMBER, orders.O_CUSTKEY, sum(O_TOTALPRICE) as sum_alias " +
"from lineitem " +
"inner join orders on lineitem.L_ORDERKEY = orders.O_ORDERKEY " +
"group by lineitem.L_LINENUMBER, orders.O_CUSTKEY "
def query = "select lineitem.L_LINENUMBER, sum(O_TOTALPRICE) as sum_alias " +
"from lineitem " +
"inner join orders on lineitem.L_ORDERKEY = orders.O_ORDERKEY " +
"group by lineitem.L_LINENUMBER"
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';"""
