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.
