The OSS accelerator preheating feature asynchronously imports OSS data into high-performance cluster storage, providing lower latency when this data is accessed later. This topic describes how to preheat data before it receives multiple access requests.
Prerequisites
An OSS accelerator is created. For more information, see Create, modify, and delete an accelerator.
Considerations
An OSS accelerator can create only one preheating task at a time, and a preheating task can be configured with a maximum of 10 path prefixes.
A preheating task takes at least 15 minutes to execute. The larger the data volume, the longer the execution time.
A preheating task occupies part of the bandwidth capacity of the accelerator. Therefore, if the bandwidth usage of the accelerator is high, the preheating task may not succeed.
Procedure
Log on to the Object Storage Service (OSS) console.
In the left-side menu bar, click Bucket List, and then click the target bucket.
In the left-side navigation pane, click . In the Operation column of the accelerator list, click Details to go to the accelerator details page, and then click Batch Preheating Tasks.
Click Create Batch Preheating Task. In the Create Batch Preheating Task dialog box, enter the task description and batch preheating paths, and select whether to start the preheating task immediately. After you complete the configuration, click OK.
In the preheating task bar, select the target preheating task and click Start to start the preheating task. The task can be executed repeatedly.
In the preheating task bar, select the target preheating task and click History to view the historical execution records of the task.
What to do next
You can use OSS accelerator together with common OSS developer tools and OSS SDKs. For more information, see Use an accelerator.
