# SHOW LOAD
|
|
## Description
|
|
This statement is used to show the execution of the specified import task
|
|
Grammar:
|
|
SHOW LOAD
|
|
[FROM both names]
|
|
[
|
|
WHERE
|
|
[LABEL [ = "your_label" | LIKE "label_matcher"]]
|
|
[STATE = ["PENDING"|"ETL"|"LOADING"|"FINISHED"|"CANCELLED"|]]
|
|
]
|
|
[ORDER BY ...]
|
|
[LIMIT limit][OFFSET offset];
|
|
|
|
Explain:
|
|
1) If db_name is not specified, use the current default DB
|
|
2) If you use LABEL LIKE, the label that matches the import task contains the import task of label_matcher
|
|
3) If LABEL = is used, the specified label is matched accurately.
|
|
4) If STATE is specified, the LOAD state is matched
|
|
5) Arbitrary column combinations can be sorted using ORDER BY
|
|
6) If LIMIT is specified, the limit bar matching record is displayed. Otherwise, all of them will be displayed.
|
|
7) If OFFSET is specified, the query results are displayed from offset. By default, the offset is 0.
|
|
8) If broker/mini load is used, the connection in the URL column can be viewed using the following command:
|
|
|
|
SHOW LOAD WARNINGS ON 'url'
|
|
|
|
## example
|
|
1. Show all import tasks of default DB
|
|
SHOW LOAD;
|
|
|
|
2. Show the import task of the specified db. The label contains the string "2014_01_02", showing the oldest 10
|
|
SHOW LOAD FROM example_db WHERE LABEL LIKE "2014_01_02" LIMIT 10;
|
|
|
|
3. Show the import task of the specified db, specify label as "load_example_db_20140102" and sort it in descending order by LoadStartTime
|
|
SHOW LOAD FROM example_db WHERE LABEL = "load_example_db_20140102" ORDER BY LoadStartTime DESC;
|
|
|
|
4. Show the import task of the specified db, specify label as "load_example_db_20140102" and state as "load", and sort it in descending order by LoadStartTime
|
|
SHOW LOAD FROM example_db WHERE LABEL = "load_example_db_20140102" AND STATE = "loading" ORDER BY LoadStartTime DESC;
|
|
|
|
5. Show the import task of the specified dB and sort it in descending order by LoadStartTime, and display 10 query results starting with offset 5
|
|
SHOW LOAD FROM example_db ORDER BY LoadStartTime DESC limit 5,10;
|
|
SHOW LOAD FROM example_db ORDER BY LoadStartTime DESC limit 10 offset 5;
|
|
|
|
6. Small batch import is a command to view the import status
|
|
curl --location-trusted -u {user}:{passwd} http://{hostname}:{port}/api/{database}/_load_info?label={labelname}
