Object-level Operations

Multipart Upload

Multipart upload allows you to upload a single object as a set of parts. Object parts can be uploaded independently and in any order. After all parts are uploaded, Riak CS assembles an object out of the parts. When your object size reaches 100MB, you should consider using multipart uploads instead of uploading the object in a single operation. Read more about multipart uploads on the overview page.
