Status: Open (was: Received)
This issue was discussed in DSpace Developer Mtg on Feb 23, 2011.
Full discussion thread follows:
[20:06] <tdonohue> https://jira.duraspace.org/browse/DS-682 : The Select
Collection step performs badly with a large number of collections.
[20:06] <stuartlewis> Did you want someone to do the loading, or the counting
for each?
[20:07] <tdonohue> stuartlewis -- i can load up next issue, if you would be
willing to count votes :)
[20:07] <stuartlewis> tdonohue: OK.
[20:07] <PeterDietz> I have a patch: https://gist.github.com/830334
[20:07] <kshepherd> DS-682 - PeterDietz has definitely been looking into this,
though there are no comments from him in JIRA yet
[20:07] <kshepherd> oh, snap :)
[20:07] <tdonohue> Excellent...PeterDietz, can we assign to you then?
[20:07] <PeterDietz> still a little work to do, see comment, //check
eperson->comm-admin
[20:07] <stuartlewis> +1 then :)
[20:08] <PeterDietz> yeah sure, tdonohue I'll take it
[20:08] <tdonohue> +1 -- assign to PeterDietz
[20:08] <kshepherd> +1
[20:08] <mhwood> +1 solution in progress
[20:08] <PeterDietz> If I spent half as much time working on things as I do
talking about them, it would be done a month ago ;)
[20:08] <stuartlewis> Any other votes? If not, +4 and assign to PeterDietz

> Project: DSpace
> Issue Type: Bug
> Affects Versions: 1.6.2
> Reporter: Robin Taylor
> Assignee: Peter Dietz
>
> The Select Collection step build a list of collections that the user is
> authorised to submit to by calling Collection.findAuthorized(...). This
> code either reads all the collections or just those in the current community
> and then checks each one to see if the user has the neccessary authorisation.
> With a large number of collections this performs badly. We have an instance
> where the user is typically only authorised to submit to one collection but
> the code reads all collections from the database and checks each one.
> Sorry, just the problem, no solution at this time.
