OSS Accelerator warm-up asynchronously preloads data into high-performance cluster storage, reducing latency for subsequent access.
Prerequisites
You have created an OSS Accelerator. Create, modify, and delete an accelerator.
Considerations
-
Only one warm-up job can run at a time per accelerator, with a maximum of 10 path prefixes per job.
-
A warm-up job takes at least 15 minutes. Larger datasets require more time.
-
Warm-up jobs consume accelerator bandwidth and may fail if bandwidth usage is already high.
Procedure
-
Log on to the OSS console.
-
In the left-side navigation pane, click Buckets, and then click the name of the target bucket.
-
In the left-side navigation pane, choose . In the Actions column, click View Details to open the accelerator details page, then click Batch Prefetch Task.
-
Click Create Batch Prefetch Task. In the Create Batch Prefetch Task dialog box, enter a job description, specify batch warm-up paths, and choose whether to start immediately. Click Finish.
-
Select the warm-up job to run and click Start. You can run the same job multiple times.
-
To view a job's execution history, select the job from the list and click Historical Records.
Next steps
OSS Accelerator works with common OSS developer tools and SDKs. Use an accelerator.
