[GitHub] [incubator-doris] HappenLee opened a new issue #4546: [ColocateJoin][Bug] Colocate join can not perceive parameters parallel_ fragment_ exec_ instance_num settings
HappenLee opened a new issue #4546:
URL: https://github.com/apache/incubator-doris/issues/4546
**Describe the bug**
Colocate join can not perceive parameters `parallel_ fragment_ exec_ instance_num` settings:
If we only hava one BE and create a table:
```
CREATE TABLE `baseall` (
`k1` tinyint(4) NULL COMMENT "",
`k2` smallint(6) NULL COMMENT "",
`k3` int(11) NULL COMMENT "",
`k4` bigint(20) NULL COMMENT "",
`k5` decimal(9, 3) NULL COMMENT "",
`k6` char(5) NULL COMMENT "",
`k10` date NULL COMMENT "",
`k11` datetime NULL COMMENT "",
`k7` varchar(20) NULL COMMENT "",
`k8` double MAX NULL COMMENT "",
`k9` float SUM NULL COMMENT ""
) ENGINE=OLAP
AGGREGATE KEY(`k1`, `k2`, `k3`, `k4`, `k5`, `k6`, `k10`, `k11`, `k7`)
COMMENT "OLAP"
DISTRIBUTED BY HASH(`k1`) BUCKETS 5
PROPERTIES (
"replication_num" = "1",
"in_memory" = "false",
"storage_format" = "V2"
);
```
do the query
```
select * from baseall b1, baseall b2 where b1.k1 = b2.k1;
```
this is a `colocate join`. Because the bucket num is 5, the instance of one fragmnet is same 5, no matter the how `parallel_ fragment_ exec_ instance_num` be set.
**Expected behavior**
the instance of one fragmnet should be ```<= parallel_ fragment_ exec_ instance_num```
