2. remove instance from cache can rollback.
i think that is a limitation for treecache but can not found any explication
about that in the treecache document.

Hi,
For currently evict policy only support node level. so I use one onde to

Had anyone tried put 1,000,000 nodes in TreeCache. when using JDBC cache

I don't know it is a bug or is my misunderstand.

Hi,
I found that statement in the jbosscache document "Eviction policies
specify the behavior of a node residing inside the cache" , that means the
policy only support NODE level?
currently, I need the such policy that support on node's value level.
E.G
set MAXVALUE of a node, if the number
15 matches
