Hi,

Can the query cache be distributed?

Thanks

Define "distributed".

"Distributed" in this case means an Apache/Tomcat cluster running web app with Hibernate persistence.

IOW, can query cache be used in a cluster? Thanks

Yes, JBossCache supports the Hibernate query cache.

Hi!
Yes, but according to official docs on http://www.hibernate.org/hib_docs/refer ... ance-cache
the "Query Cache" and "Cluster Safe" are mutually exclusive - as shown on the chart - JBoss Tree Cache is Cluster safe, but does not support Query Cache. Is it correct? Pleasy, clarify.

Thank you.

This is not up-to-date, I'll fix it. JBossCache supports the query cache, but only if times are synchronized in your cluster, e.g. via NTP.
