[feature-wip](MTMV) Support importing data to materialized view with
multiple tables (#14944)
## Use Case
create table t_user(
event_day DATE,
id bigint,
username varchar(20)
)
DISTRIBUTED BY HASH(id) BUCKETS 10
PROPERTIES (
"replication_num" = "1"
);
insert into t_user values("2022-10-26",1,"clz");
insert into t_user values("2022-10-28",2,"zhangsang");
insert into t_user values("2022-10-29",3,"lisi");
create table t_user_pv(
event_day DATE,
id bigint,
pv bigint
)
DISTRIBUTED BY HASH(id) BUCKETS 10
PROPERTIES (
"replication_num" = "1"
);
insert into t_user_pv values("2022-10-26",1,200);
insert into t_user_pv values("2022-10-28",2,200);
insert into t_user_pv values("2022-10-28",3,300);
DROP MATERIALIZED VIEW if exists multi_mv;
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 t_user.username, t_user_pv.pv from t_user, t_user_pv where
t_user.id=t_user_pv.id;
