sceneryback opened a new issue #3697:
URL: https://github.com/apache/incubator-doris/issues/3697
version: apachedoris/doris-dev:build-env-1.2
Json format in kafka, not array:
```
{
"id": "xxx",
"a": {
"id": "xxx"
}
}
```
a.id is in format like '11:22:33:44:55:66'
Create Table:
```
CREATE TABLE `test` (
`a_id` varchar(24) not null
)
DUPLICATE KEY(`a_id`)
DISTRIBUTED BY HASH(`a_id`) BUCKETS 4
PROPERTIES (
"storage_type" = "COLUMN",
"replication_num" = "1"
);
```
Create load routine:
```
CREATE ROUTINE LOAD testdb.test_load ON test
COLUMNS(a_id)
PROPERTIES
(
"desired_concurrent_number"="3",
"max_batch_interval" = "20",
"max_batch_rows" = "300000",
"max_batch_size" = "209715200",
"strict_mode" = "false",
"format" = "json",
"jsonpaths" = "[\"$.a.id\"]"
)
FROM KAFKA
(
"kafka_broker_list" = "xxx",
"kafka_topic" = "yyy"
);
```
BUT results in table are:
```
select distinct a_id from test limit 5
```
+----------+
| 1 |
| 1 |
| 1 |
| 1 |
| 1 |
+----------+
Seems it only loads the first character in a.id
