qzsee opened a new pull request, #21906:
URL: https://github.com/apache/doris/pull/21906
## Proposed changes
for example
```sql
CREATE TABLE `colocate_a` (
dt date,
k1 int,
v1 int
) ENGINE=OLAP
DUPLICATE KEY(`k1`)
PARTITION BY RANGE(`dt`)
(PARTITION p1 VALUES [('2022-10-02'), ('2022-10-03'))
DISTRIBUTED BY HASH(`k1`) BUCKETS 2
PROPERTIES (
"replication_num" = "3",
"in_memory" = "false",
"storage_format" = "V2"
);
ALTER TABLE colocate_a set ("colocate_with" = "ab");
CREATE TABLE `colocate_b` (
dt date,
k1 int,
v1 int
) ENGINE=OLAP
DUPLICATE KEY(`k1`)
PARTITION BY RANGE(`dt`)
(PARTITION p1 VALUES [('2022-10-02'), ('2022-10-03'))
DISTRIBUTED BY HASH(`k1`) BUCKETS 2
PROPERTIES (
"replication_num" = "3",
"in_memory" = "false",
"storage_format" = "V2"
);
ALTER TABLE colocate_b ADD PARTITION p2 VALUES
[("2022-10-03"),("2022-10-04")) DISTRIBUTED BY HASH(k1) BUCKETS 10;
ALTER TABLE colocate_b set ("colocate_with" = "ab");
```
table `colocate_b` partition p2 set bucket num is 10 then take it into group
`ab`.
In `ColocateTableCheckerAndBalancer` matchGroup occur :
```
