How can I scale my request rate to S3, to improve request rate performance?

Last updated: 2022-11-22

I expect my Amazon Simple Storage Service (Amazon S3) bucket to get high request rates. What object key naming pattern should I use to get better performance?

Resolution

Amazon S3 automatically scales by dynamically optimizing performance in response to sustained high request rates. Your application can achieve 3,500 PUT/COPY/POST/DELETE or 5,500 GET/HEAD requests per second per prefix in a bucket. There are no limits to the number of prefixes in a bucket. You can increase your read or write performance by using parallelization. If Amazon S3 is optimizing for a new request rate, you receive a temporary HTTP 503 request response until the optimization completes. Because Amazon S3 optimizes its prefixes for request rates, unique key naming patterns are no longer a best practice.
