      Description

      Currently it relies on the default implementation of FileSystem. But it would be good to explore using TransferManager.download() (Ref: https://java.awsblog.com/post/Tx3Z7NO7C2TVLB/Parallelizing-Large-Downloads-for-Optimal-Speed for recent aws-sdk-java). When aws-sdk version is bumped it,it would automatically get the benefit of parallel download sas well.
