Class SequentialMultipartUploadStrategy

java.lang.Object
  org.jclouds.aws.s3.blobstore.strategy.internal.SequentialMultipartUploadStrategy

All Implemented Interfaces:

MultipartUpload, MultipartUploadStrategy

public class SequentialMultipartUploadStrategy
extends Object
implements MultipartUploadStrategy

Provides a sequential multipart upload strategy. The file partitioning algorithm: The default partition size we choose is 32mb. A multiple of this default partition size is used. The number of parts first grows to a chosen magnitude (for example 100 parts), then it grows the partition size instead of number of partitions. When we reached the maximum part size, then again it starts to grow the number of partitions.
