Workspace - concept

Hi to all,

I just thinking about the best way of using the workspaces in conjunction with user/rights management for an application using JCR/Jackrabbit as storage:
1. Every user gets his/her own workspace
Advantage: all data is clearly separated, the user/rights management must only deals with workspace-wide constraints (perhaps nearly the node-wide access management can be left out); no problem with workspace-wide indexing (I see that the workspace contains the index of the data; if I think correct, taht would mean, that anyone can search for key words, but some keywords perhaps should not be seen by all users)
Disadvantage: this can be perhaps many thousends workspaces (I have no idea at the moment if this can be handled)

2. One global workspace, all users connect through this workspace
Advantage: links to other nodes in another tree-part can be established; easier handling of this one workspace
Disadvantage: can all users search for "keywords" which they should not see? (if the whole index is shared by all users); more handling of ACL-constraints on the per-node-basis; very big workspace with big index

So, I would like to know, if someone had some experiences, which concept to use in practice with very big data (could be about 2TB in the next 2-5 years) and many thousend users.

Thanks in advance,
Ulrich

Hi Chad,

that's a good statement and matters much to me. I am a friend of standarized usages (because it's most economic). Thanks for that. And if workspaces are not designed for that, I won't use them for that.

Best regards,
Ulrich

I don't know if this counts as a "real life" issue . . .   The
workspace usage you describe in #1 is clearly not a common practice in
the Jackrabbit community.  I've found that departures from the way the
community is using Jackrabbit can quickly lead you into a less
finished part of the software.  Perhaps this doesn't matter to you,
but my experiences with Jackrabbit are:

1) good software

2) the farther you stray from the standard community usage patterns,
the more time you can expect to spend figuring it out for yourself and
debugging
