[GitHub] [doris] chenlinzhong opened a new pull request, #15948: [mtmv](opt) mtmv task use original query stmt so that user can set var more flexible

chenlinzhong opened a new pull request, #15948:
URL: https://github.com/apache/doris/pull/15948

   # Proposed changes
   mtmv task use original query stmt so that user can set var more flexible, for example set  query_timeout, exec_mem_limit etc
   though ``CREATE MATERIALIZED VIEW`` statement
   
   ```
   CREATE MATERIALIZED VIEW  multi_mv
   BUILD IMMEDIATE 
   REFRESH COMPLETE 
   start with "2022-10-27 19:35:00"
   next  60 second
   KEY(username)   
   DISTRIBUTED BY HASH (username)  buckets 1
   PROPERTIES ('replication_num' = '1') 
   AS 
   select  /*+set_var(query_timeout=1000)*/ t_user.username, t_user_pv.pv  from t_user, t_user_pv where t_user.id=t_user_pv.id;
   ```
   
   mtmv task will  use the original stmt  when insert data to table 
   ```
   select  /*+set_var(query_timeout=1000)*/ t_user.username, t_user_pv.pv  from t_user, t_user_pv where t_user.id=t_user_pv.id;
   ```
   instead of 
   ```
   select  t_user.username, t_user_pv.pv  from t_user, t_user_pv where t_user.id=t_user_pv.id;
   ```
