group by array<json>字段导致be宕机

【详述】group by的字段类型为array时，导致be宕机

建表语句：
CREATE TABLE test_json_001 (
id int(11) NULL COMMENT “”,
aa json NULL COMMENT “”,
bb ARRAY NULL COMMENT “”
) ENGINE=OLAP
DUPLICATE KEY(id)
COMMENT “OLAP”
DISTRIBUTED BY HASH(id) BUCKETS 3
PROPERTIES (
“replication_num” = “3”,
“in_memory” = “false”,
“storage_format” = “DEFAULT”,
“enable_persistent_index” = “false”,
“compression” = “LZ4”
);

导致be宕机的sql：
select bb,count(1) from rx_bd_test.test_json_001 group by bb;

【业务影响】
【StarRocks版本】2.5.2
【集群规模】3fe+3be（fe与be混部）

数据表；
CREATE TABLE rx_bd_test.test_ods_001 (
id int,
aa string
) ENGINE=OLAP
DUPLICATE KEY(id)
COMMENT “OLAP”
DISTRIBUTED BY HASH(id) BUCKETS 3
PROPERTIES (
“replication_num” = “3”,
“in_memory” = “false”,
“storage_format” = “DEFAULT”,
“enable_persistent_index” = “false”,
“compression” = “LZ4”
);

插入数据：
insert into rx_bd_test.test_json_001 values(1, ‘{“k1”:“v1”,“k2”:“v2”}’, ‘[{“k1”:“v1”,“k2”:“v2”},{“k3”:“v3”,“k4”:“v4”}]’);

导入到查询的目标表：
insert into rx_bd_test.test_json_001
SELECT
1 as id
, json_query(parse_json(aa), ‘$.k3’) as aa
, json_query(parse_json(aa), ‘$.k4’) as bb
from rx_bd_test.test_ods_001
;

查询sql：
select bb,count(1) from rx_bd_test.test_json_001 group by bb;

好的 我尝试复现下 稍等

复现了该问题 我们修复下 有进展会在此帖子下同步

ok，麻烦大佬了

大佬，这个问题有修复安排吗？什么版本发布？

您好 这个问题当前会在2.5.5版本进行修复

ok，多谢大佬 ，

@U_1647419731669_9072 SR 还不支持 group by JSON， group by array，你们具体是怎样的需求？
