After this PR #9272, the `docs/build_help_zip.sh` will run failed. This PR fix this issue. But the help module still has some parse problem, I will fix it in next PR. This CL mainly changes: 1. fix `docs/build_help_zip.sh` error 2. remove `sql-reference-v2` to `sql-reference` 3. modify build extension github action to run `docs/build_help_zip.sh`

|
|
### Name
|
|
|
|

|
|
查看一个指定的 Routine Load 作业的当前正在运行的子任务情况。
|
|

|
|
```

|
TaskId: d67ce537f1be4b86-abf47530b79ab8e6
|
|
TxnId: 4
|
|
TxnStatus: UNKNOWN
|
|
JobId: 10280
|
|
CreateTime: 2020-12-12 20:29:48
|
|
ExecuteStartTime: 2020-12-12 20:29:48
|
|
Timeout: 20
|
|
BeId: 10002
|
|
DataSourceProperties: {"0":19}
|
|
```
|
|
|
|
- `TaskId`：子任务的唯一 ID。
|
|
- `TxnId`：子任务对应的导入事务 ID。
|
|
- `TxnStatus`：子任务对应的导入事务状态。通常为 UNKNOWN。并无实际意思。
|
|
- `JobId`：子任务对应的作业 ID。
|
|
- `CreateTime`：子任务的创建时间。
|
|
- `ExecuteStartTime`：子任务被调度执行的时间，通常晚于创建时间。
|
|
- `Timeout`：子任务超时时间，通常是作业设置的 `MaxIntervalS` 的两倍。
|
|
- `BeId`：执行这个子任务的 BE 节点 ID。
|
|
- `DataSourceProperties`：子任务准备消费的 Kafka Partition 的起始 offset。是一个 Json 格式字符串。Key 为 Partition Id。Value 为消费的起始 offset。
|
|
|
|
### Example
|
|
|
|
1. 展示名为 test1 的例行导入任务的子任务信息。
|
|
|
|
```sql
|
|
SHOW ROUTINE LOAD TASK WHERE JobName = "test1";
|
|
```
|
|
|
|
### Keywords
|
|
|
|
SHOW, ROUTINE, LOAD, TASK
|
|
|
|
### Best Practice
|
|
|
|
通过这个命令，可以查看一个 Routine Load 作业当前有多少子任务在运行，具体运行在哪个 BE 节点上。
