Richard Rodgers commented on DS-1205:
-------------------------------------
Another, possibly slightly more performant, solution would be to count items
read, and flush (clear) the cache every 'n' times (or query the cache with
'getCacheSize()'). where 'n x item size' fits comfortably inside the memory
allocated to the JVM heap.
But you are quite right that DSpace lacks the ability to 'optionalize' the use
of the cache where one naturally would want to (essentially read-only cases).

> 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.
