Name

SHOW LOAD

Description

This statement is used to display the execution of the specified import task

grammar:

1. SHOW LOAD
2. [FROM db_name]
3. [
4. WHERE
5. [LABEL [ = "your_label" | LIKE "label_matcher"]]
6. [STATE = ["PENDING"|"ETL"|"LOADING"|"FINISHED"|"CANCELLED"|]]
7. ]
8. [ORDER BY...]
9. [LIMIT limit][OFFSET offset];

illustrate:

  1. If db_name is not specified, the current default db is used
  2. If LABEL LIKE is used, it will match import tasks whose label contains label_matcher
  3. If LABEL = is used, it will match the specified label exactly
  4. If STATE is specified, matches the LOAD state
  5. You can use ORDER BY to sort on any combination of columns
  6. If LIMIT is specified, limit matching records are displayed. Otherwise show all
  7. If OFFSET is specified, the query results are displayed starting at offset offset. By default the offset is 0.
  8. If you are using broker/mini load, the connections in the URL column can be viewed using the following command:

1. SHOW LOAD WARNINGS ON 'url'

Example

  1. Show all import tasks for default db

1. SHOW LOAD; 2. Display the import tasks of the specified db, the label contains the string “2014_01_02”, and display the oldest 10

1. SHOW LOAD FROM example_db WHERE LABEL LIKE "2014_01_02" LIMIT 10; 3. Display the import tasks of the specified db, specify the label as “load_example_db_20140102” and sort by LoadStartTime in descending order

1. SHOW LOAD FROM example_db WHERE LABEL = "load_example_db_20140102" ORDER BY LoadStartTime DESC; 4. Display the import task of the specified db, specify the label as “load_example_db_20140102”, the state as “loading”, and sort by LoadStartTime in descending order

1. SHOW LOAD FROM example_db WHERE LABEL = "load_example_db_20140102" AND STATE = "loading" ORDER BY LoadStartTime DESC; 5. Display the import tasks of the specified db and sort them in descending order by LoadStartTime, and display 10 query results starting from offset 5

1. SHOW LOAD FROM example_db ORDER BY LoadStartTime DESC limit 5,10; 2. SHOW LOAD FROM example_db ORDER BY LoadStartTime DESC limit 10 offset 5; 6. Small batch import is a command to check the import status

1. curl --location-trusted -u {user}:{passwd} http://{hostname}:{port}/api/{database}/_load_info?label={labelname}
