[wyxxxcat]

now:

CREATE TABLE t (
    id int,
    test int,
    `k` int
)
DUPLICATE KEY(`id`)
PARTITION BY range(`id`) (
    partition p1 values less than (5),
    partition p2 values less than (10)
)
DISTRIBUTED BY HASH(`id`) BUCKETS 1
PROPERTIES (
    "replication_num" = "1"
);

insert into t values (1,1,1);
insert into t values (1,2,1);
insert into t values (1,3,1);

CREATE MATERIALIZED VIEW mv
BUILD IMMEDIATE REFRESH AUTO
PROPERTIES ('replication_num' = '1')
AS (select test, id from t);
