----------------------------------
Summary: Reduce getBucket API invocations in S3 bucket owner
verification
Key: HDDS-13270
URL: https://issues.apache.org/jira/browse/HDDS-13270
Project: Apache Ozone
Issue Type: Improvement
Components: s3gateway
Reporter: Hsu Han Wen
As part of HDDS-10775, bucket owner verification was added to support
S3-compatible behavior using the {{x-amz-expected-bucket-owner}} and
{{x-amz-source-expected-bucket-owner}} headers.
To perform the verification, a {{getBucket}} call is made to obtain the bucket
owner's information. However, this results in an additional OM RPC call even
for normal requests that do not include these headers. This may introduce
unnecessary latency, especially for high-throughput S3 workloads.
This Jira aims to optimize the behavior by avoiding {{getBucket}} calls unless
one of the expected bucket owner headers is explicitly present. This would
slightly increase the logic complexity but help reduce RTT and improve
performance for general requests.
