David E. Jones commented on OFBIZ-4098:
---------------------------------------
This is an interesting request. For Moqui (www.moqui.org) I decided to go with
ehcache itself for the cache implementation. The cache interface design I
started with was based on the OFBiz cache API, and most of it worked pretty
well but there were a few mismatches, and quite a few things I got rid of in
the cache design because ehcache just doesn't support them.
Anyway, the implementation ends up being quite simple, the cache wrapper and
factory in Moqui are complete and available here:
http://moqui.svn.sourceforge.net/viewvc/moqui/trunk/moqui/framework/impl/src/org/moqui/impl/context/CacheImpl.groovy?view=markup
http://moqui.svn.sourceforge.net/viewvc/moqui/trunk/moqui/framework/impl/src/org/moqui/impl/context/CacheFacadeImpl.groovy?view=markup
Chances are it would only take a few hours to implement this in OFBiz (plus
time for whatever configuration mechanism you decide on, which is messy), but
you would have to leave out (effectively disable) certain features that the
OFBiz UtilCache supports. For example, I never could figure out how to get soft
references working in ehcache.

> Hello,
> I would like to contribute a patch to enable switching from Ofbiz native
> Cache (today UtilCache) to another implementation like EhCache for example.
> To avoid big code impacts, UtilCache would stay the same and delegate to the
> real
> cache implementation this will impact less classes and big impacts
> would stay in UtilCache package.
> Ability to plug another implementation like EhCache for example would enable
> easily plugin with Terracota for example which on big Web Site gives much
> performance enhancements.
> Is the format to contribute this kind of evolution also a patch ?
> Thank you
> Regards
> Philippe
