Artifactory’s S3 provider offers the same multipart upload mechanism for both AWS SDK v1 and v2. Multipart upload is configured by the parameters multiPartLimit and multipartElementSize.
When using AWS SDK v2, the multipart upload operation is performed using the CRT client. This client aims for high throughput. This means that the CRT client with SDK v2 may trigger a high amount of requests to upload parts to the S3 storage.
If you need to upload less parts, consider decreasing multiPartLimit to have fewer multipart uploads, or increasing multipartElementSize for uploading parts with a bigger size. If your use case involves generally uploading large binaries, consider increasing multipartElementSize.
