> Key: ATLAS-2843
> URL: https://issues.apache.org/jira/browse/ATLAS-2843
> Project: Atlas
> Issue Type: Bug
> Components: atlas-core
> Affects Versions: 0.8.3
> Reporter: Ashutosh Mestry
> Assignee: Ashutosh Mestry
> Priority: Major
> Fix For: 0.8.3
>
> Attachments: ATLAS-2843-AtlasClient-updates-for-exportData-and-im.patch
>
>
> *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.
