"message":"It is now possible to disable payload signing through an operation customization.\n\n```rust\nasync fn put_example_object(client: &aws_sdk_s3::Client) {\n let res = client\n .put_object()\n .bucket(\"test-bucket\")\n .key(\"test-key\")\n .body(ByteStream::from_static(b\"Hello, world!\"))\n .customize()\n // Setting this will disable payload signing.\n .disable_payload_signing()\n .send()\n .await;\n}\n```\n\nDisabling payload signing will result in a small speedup at the cost of removing a data integrity check.\nHowever, this is an advanced feature and **may not be supported by all services/operations**.\n",
