    ->   id bigint,
    ->   username varchar(20)
    -> )
    -> DISTRIBUTED BY HASH(id) BUCKETS 10
    -> PROPERTIES ('replication_num' = '1');
Query OK, 0 rows affected (0.07 sec)

mysql> CREATE TABLE t_user_pv(
    ->   event_day DATE,
    ->   id bigint,
    ->   pv bigint
    -> )
    -> DISTRIBUTED BY HASH(id) BUCKETS 10
    -> PROPERTIES ('replication_num' = '1');
Query OK, 0 rows affected (0.09 sec)

    -> BUILD IMMEDIATE REFRESH COMPLETE
    -> KEY (username)
    -> DISTRIBUTED BY HASH(username) BUCKETS 10
    -> PROPERTIES ('replication_num' = '1')
    -> AS SELECT /*+ SET_VAR(exec_mem_limit=1048576, query_timeout=3600) */ t1.username ,t2.pv FROM t_user t1 LEFT JOIN t_user_pv t2 on t1.id = t2.id;
