>
> S3 offers persistence only when uploads are complete. That means at the end
> of simple uploads and uploads of parts of a MultiPartUpload.
> We should implement a RecoverableWriter for S3 that does a MultiPartUpload
> with a Part per checkpoint.
> Recovering the reader needs the MultiPartUploadID and the list of ETags of
> previous parts.
> We need additional staging of data in Flink state to work around the fact that
> - Parts in a MultiPartUpload must be at least 5MB
> - Part sizes must be known up front. (Note that data can still be streamed
> in the upload)
