DSpace @ Lyncode commented on DS-1205:
--------------------------------------
Yes, that makes sense, thanks. I agree on the performance issue. Disagree on
the actual implementation (not optional usage).
However, documentation could be improved in order to explain this detail.
https://wiki.duraspace.org/display/DSDOC18/Storage+Layer
I'm just worried about new developers, they should be aware of this detail, by
means using the DSpace Storage Layer requires caution at this level. I did
found the problem after some deep analysis.
I agree with you, this implementation doesn't work, because EhCache is a global
cache mechanism, and this simple map is a context based (request based) caching
system.

> Key: DS-1205
> URL: https://jira.duraspace.org/browse/DS-1205
> Project: DSpace
> Issue Type: Bug
> Components: DSpace API
> Affects Versions: 1.8.2
> Reporter: DSpace @ Lyncode
> Priority: Blocker
> Labels: Core
> Fix For: 3.0
>
>
> bin/dspace script is crashing with OutOfMemory problems related with the
> org.dspace.core.Context HashMap.
> Proof: https://github.com/lyncode/DSpace/issues/5
> I think this is a critical problem, mainly because it does not make sense
> (for me) to have crashing applications because of caching mechanism memory
> overusage. As good practices for implementing caches, this cache mechanism
> could be aware of it's memory usage threshold, if reached, it could start
> discarding old and unused objects in it.
