Object Storage Service:0004-00000302

Last Updated:Jul 21, 2023

Problem description

The queries per second (QPS) limit is exceeded.

Causes

The number of times that your Alibaba Cloud account accesses OSS is excessively high. The QPS limit is exceeded.

Examples

None

Solutions

Reduce the frequency at which you send requests. The maximum QPS for an Alibaba Cloud account is 10,000. The actual values vary based on the following read and write modes:

  • Sequential read and write: 2,000

    If you upload a large number of objects and the names of the objects contain sequential prefixes such as timestamps and letters, multiple object indexes may be stored in a single partition. In this case, if you send a large number of requests to query these objects, latency may increase. We recommend that you do not upload a large number of objects whose names contain sequential prefixes. For more information about how to change sequential prefixes to random prefixes, see OSS performance and scalability best practices.

  • Non-sequential read and write: 10,000

If your business requires a greater QPS, contact technical support.
