Example 2 with CompleteMultipartUploadRequest

use of com.emc.object.s3.request.CompleteMultipartUploadRequest in project pravega by pravega.

the class ExtendedS3Storage method doConcat.

/**
 * The concat is implemented using extended S3 implementation of multipart copy API. Please see here for
 * more detail on multipart copy:
 * http://docs.aws.amazon.com/AmazonS3/latest/dev/CopyingObjctsUsingLLJavaMPUapi.html
 *
 * The multipart copy is an atomic operation. We schedule two parts and commit them atomically using
 * completeMultiPartUpload call. Specifically, to concatenate, we are copying the target segment T and the
 * source segment S to T, so essentially we are doing T <- T + S.
