> The Stargate data model supports packaging up a bunch of rows for a multi-put and for returning multiple rows out of a scanner in batch. The data model supports multi-get also but this is not currently implemented -- gets are driven by HTTP transactions requesting path specified resources, with widest scope being the row, as is the REST way. This issue is about how to maintain RESTful sematics on the one hand but also support multi-put _and_ multi-get; furthermore, to return results from multi-get and scanners in a streaming manner. Investigate Jersey multipart support. Can it support streaming the equivalent of List<RowResult>? Would it do the right thing given a list of models to marshal and send along? 
> Acccording to this -- http://n2.nabble.com/Hello-World-and-Welcome-to-jersey-multipart-td1343189.html -- the situation looks promising:

> The need for cleanup() is because the implementation knows how to buffer "large" body parts to temporary files on disk, so you don't blow away your JVM heap on a multi-gigabyte upload or download.

> I would prefer an API that does pure streaming, not store and forward, but that might be good enough.
