Re: [eclipselink-users] Lifetime of Transient lists in the cache

[Tim Hollosy <hollosyt@xxxxxxxxx>]

The query caching works well, I've also had very good luck with ehcache, it's a dead simple cache to configure and is very lightweight. There is even a project that adds @Cacheable annotations for use with Spring.

Thanks Tom.

That looks interesting. I could combine QueryHints with the list
holder. I would still need the list holder, so it would be interesting
to know how the list holder expires.

Kind Regards,
