SHOW-LOAD-PROFILE

Name

SHOW LOAD PROFILE

caution

Since 2.1.1, this syntax is deprecated.

Description

This statement is used to view the Profile information of the import operation. This function requires the user to open the Profile settings. The versions before 0.15 perform the following settings:

SET is_report_success=true;

Versions 0.15 and later perform the following settings:

SET [GLOBAL] enable_profile=true;

grammar:

show load profile "/";

show load profile "/[queryId]"

show load profile "/[queryId]/[TaskId]"

show load profile "/[queryId]/[TaskId]/[FragmentId]/"

show load profile "/[queryId]/[TaskId]/[FragmentId]/[InstanceId]"

This command will list all currently saved import profiles. Each line corresponds to one import. where the QueryId column is the ID of the import job. This ID can also be viewed through the SHOW LOAD statement. We can select the QueryId corresponding to the Profile we want to see to see the specific situation

Example

1. List all Load Profiles

   mysql> show load profile "/"\G
