>             Project: Atlas
>          Issue Type: Bug
>          Components:  atlas-core
>    Affects Versions: 0.8.3
>            Reporter: Ashutosh Mestry
>            Assignee: Ashutosh Mestry
>            Priority: Major

>
> *Background*
> Existing implementation of _AtlasClient.exportData and AtlasClient.importData_ converts the stream returned by the REST APIs to _byte_ array and then passes it on to the caller. 
> In case of _importData_ with absolute file path, it converts it to byte array and then writes the bytes to the file.
> This is inefficient from memory perspective and may cause problems on client-side if the data is large.
> *Solution*
>  * The APIs should return streams.
>  * The API that writes file, should implement a version that works with streams.
