TOS accelerator

Creating warm-up tasks

The TOS accelerator enables asynchronous warm-up, pre-caching relevant data within the acceleration scope. The next time the data is accessed, it loads faster. This topic introduces notes and steps for creating warm-up tasks.

Notes

Warm-up tasks only cache data within the acceleration scope.

Warm-up tasks run for at least 15 minutes. Larger data volumes require more time to execute. Thank you for your patience.

Warm-up tasks use some of the accelerator’s read bandwidth. The warm-up bandwidth is determined by the formula: Min{TOS accelerator bandwidth − Actual read request bandwidth, TOS accelerator bandwidth × 10%}. If the accelerator's bandwidth utilization is high, some objects may not be pre-cached.

Steps

In the left navigation pane, click TOS accelerator.

On the TOS accelerator page, click the accelerator you want to manage.

On the accelerator details page, click the warm-up task tab, and then click Create warm-up task.

In the New warm-up task dialog box, configure the following parameters:

Parameter	Description
Destination	The name of your accelerator is displayed by default.
Source	Set the path for the data to be pre-cached. Requirements: You can only select a path that is configured for the acceleration strategy. You can add up to 10 paths.
Describe	The description for the warm-up task.
Execute immediately	Choose whether to run the warm-up task right after it has been successfully created.

Once you have finished configuring, click OK.

After creating a warm-up task, you can view its status in the warm-up task list. The task statuses are explained below.

Idle: The task has not started or has finished.

Executing: The task is in progress.

Stopping: The task is exiting from the executing state.

Related operations

You can also perform these actions on the warm-up task tab of an accelerator's details page:

Operation	Steps
Start a warm-up task	Click Start in the Actions column of the task.
Stop a warm-up task	Click Stop in the Actions column of the task.
Modify a warm-up task	Click Modify in the Actions column of the task. In the Edit warm-up task dialog box, modify the parameters as needed. tip You can only modify a warm-up task when its status is idle.
Delete a warm-up task	Click Delete in the Actions column of the task. Then, confirm the deletion by clicking Delete in the box that appears. tip You can only delete a warm-up task when its status is idle.
View task history	Click historical record in the Actions column of the task. Then, view the task history in the box that appears.
