[JBoss JIRA] (WFLY-6596) WrongClassException when using infinispan as remote-store for hibernate entity cache

Radim Vansa commented on WFLY-6596:
-----------------------------------
[~sebersole] It is leading to shared cache region (for all entities) because with the
mentioned configuration the entity caches are merely proxies to single cache located in
different cluster.
[~gvwolf3d] So I understand that your DB is so heavily used that adding one RPC to the
remote cluster upon each read (which fails if the entity is missing) is still better than
trying to read it from DB directly. Do you have any estimate of modifications vs. reads?
We have considered implementing 2LC on top of Hot Rod protocol (Infinispan's native =
most efficient way to talk to remote cluster) but the cost above always seemed to high.
There was some hope that with near caching (keeping some entries on clients = exactly what
you don't want to do) this could be viable, but later we've realized that we could
not keep strict consistency guarantees with this near cache. However, your case supports
the idea that 2LC on Hot Rod without near cache could be worthwhile as well.
