**Introduce routine load job statistic system table:**
```
mysql> show create table information_schema.routine_load_job\G
*************************** 1. row ***************************
Table: routine_load_job
Create Table: CREATE TABLE `routine_load_job` (
`JOB_ID` text NULL,
`JOB_NAME` text NULL,
`CREATE_TIME` text NULL,
`PAUSE_TIME` text NULL,
`END_TIME` text NULL,
`DB_NAME` text NULL,
`TABLE_NAME` text NULL,
`STATE` text NULL,
`CURRENT_TASK_NUM` text NULL,
`JOB_PROPERTIES` text NULL,
`DATA_SOURCE_PROPERTIES` text NULL,
`CUSTOM_PROPERTIES` text NULL,
`STATISTIC` text NULL,
`PROGRESS` text NULL,
`LAG` text NULL,
`REASON_OF_STATE_CHANGED` text NULL,
`ERROR_LOG_URLS` text NULL,
`USER_NAME` text NULL,
`CURRENT_ABORT_TASK_NUM` int NULL,
`IS_ABNORMAL_PAUSE` boolean NULL
) ENGINE=SCHEMA;
1 row in set (0.00 sec)
```
**There are some benefits to empower job with SQL query capability for
statistical information:**
- It can be used in conjunction with metrics add through
https://github.com/apache/doris/pull/48209 to roughly locate abnormal
jobs when Grafana alarms, and the following SQL can be used:
```
SELECT JOB_NAME
FROM information_schema.routine_load_job_statistics
WHERE CURRENT_ABORT_TASK_NUM > 0
OR IS_ABNORMAL_PAUSE = TRUE;
```
- User can use the `select * from information_schema.routine_load_job`
instead of the `show routine load`. The advantage is that the `show
routine load` can only be searched by name, but SQL can be very flexible
in locating jobs
