Using JSR-107 for jackrabbit caches?

["Padraic I. Hannon" <pi...@wasabicowboy.com>]

Not sure if this has been brought up, however, has this group considered 
moving towards using the JSR-107 spec for the internal jackrabbit 
caching? This would enable us to use a more pluggable cache model. Thoughts?

Yeah that is what I was thinking about, this jsr is also known as  
JCache. Perhaps it is not as supported as I thought, but basically  
everything looks like a Map. My thought is that by using such an  
interface or by making the cache system pluggable is that we could  
swap out cache providers for different scenarios. One thing we are  
interested in looking at is using Coherence (http://www.tangosol.com/coherence-overview.jsp 
) which is used by atlassian and others for to allow for scaling. This  
combined with a pluggable persistence model would allow for different  
cluster implementations. I would also be interested in looking at  
terracotta (http://www.terracotta.org/confluence/display/orgsite/Home)  
or swarmcache (http://swarmcache.sourceforge.net/). While there could  
be a lot of work to create a fully clusterable/grid-ed version of  
jackrabbit with pluggable cache and persistence managers we might be  
able to do this using existing projects. One cool thing is that a lot  
of these distributed caches support read-through and write-through (or  
even write-behind) semantics for caching which could create an  
extremely scalable solution for accessing content using jcr.

Hi,

Do you mean https://jsr-107-interest.dev.java.net/ ? I have never
heard about this JSR, but it sounds interesting. Is it still active? I
saw the last update was on 01/19/2005. It says "Draft Specification:
coming soon!". Maybe it would be better to wait until the
specification is available?

Could you explain the use case? Why do you need a more pluggable cache model?

Thomas
