[Building Sakai] Alternatives to Session State These Days

[Steven Githens]

Hi Dev,

I need to store a list of sorted UUID's ( String[] ) for a user to page 
through grading students assignments.  Because of the current structures 
of things, the page actually needs to refresh, etc, so I need to store 
this on the server.  I really do need to store it as well, because the 
potential ordering of the data is expected to change during the course 
of working with it, but we want to keep the original order for working 
through.

In Sakai 2.7+ I've been trying to determine the best way to do this 
using minimal session storage.  And because it very large cases I'm not 
sure I would want to store it, even if just briefly.

To avoid having to make a separate table (or maybe using a file in 
resources), I've been looking at the Caching in the Memory service. 

Does this seem like an appropriate domain of the Memory Service?  
Storing interim results of things that users are paging through in tables?

Maximum cheers,
Steve
