Summary: high throughput using prevayler persistence?

Initial Comment:
Hi there

Just wondering if anyone has given thought to using
prevayler as the persistence layer.

Prevayler serializes writes to a log file on disk. It also
caches java objects in memory.

For JMS apps focussed on high throughput, I'm thinking
that prevayler might be able to give a large performance
boost.

For example, it claims 3000x performance boost
compared to MySQL for queries. See
http://www.prevayler.org/wiki.jsp

Thanks
edward

No. We're moving towards supporting only JDBC based
persistent solutions. Prevayler also seems to require all
persistent objects to be able to reside in memory - not
applicable to applications such as OpenJMS where the no. of
persistent objects is dynamic.
