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?

What is it you're suggesting to mention on Google+ ? The "reference data cache" or the zero-level cache? I wouldn't mind seeing both, these things deserve some more publicity. Would be nice to have a blog on the reference cache too.
