[weld-dev] [seam-dev] Weld/Seam in the cloud

[Pete Muir]

Hi Sanne,

Yes, as part of the "integrating with distributed databases" we did talk a bit about how the Hibernate Search is a good match for the cloud. Really, this item on the todo list is more of a documentation/blog/tutorial issue, than something we can address IMO. Something to make sure people are aware of...

This can then be read in when the app starts, rather than using reflection to study the classes. This may lead to faster boot (needs research!)
