[hibernate-dev] Patches for using Hibernate in low-latency environments

Interesting read.  I do wonder though about the types of data 
specifically where this would be useful.  As they say they, a "trading 
application typically receives several thousand market data events per 
second".  There are so many trades, one would think, that holding them 
all in memory (in this zero-level cache) would be a big drain on 
available memory space.  I am curious if the types of data they expect 
to handle that way match up with our "reference data cache" caching 
capabilities added in ORM 4.2

I know we have discussed similar before, but what do you think about 
mentioning this on the Hibernate Google+ page?
