… group by (apache#39041) this is brought by apache#34185 if query external table without group by, rewrite by materialized view will fail such as mv def is select o_custkey, o_orderdate from ${hive_catalog_name}.${hive_database}.${hive_table}; query is query external table directly as following, this would fail when try to rewrte by materialized view select o_custkey from ${hive_catalog_name}.${hive_database}.${hive_table}; this pr fix the problem.
…terialized view (apache#38958) This is brought by apache#34274 if mv def is select o_orderdate from orders group by o_orderdate; query is as followiing, the result is wrong. select 1 from orders group by o_orderdate;
…an for performance (apache#39541) Before query rewrite by materialized view, we collecet the table which query used by method org.apache.doris.mtmv.MTMVCache#from. In MTMVCache#from we calcute the cost of plan which is useless for collecting table. So add boolean needCost param in method MTMVCache#from to identify that if need cost of plan or not for performance.
