I would need to handle puts as well, since I can't predict how someone is using POJO Cache. They could retrieve an object, wait for some period time (during which the data has been gravitated to another node), then trigger an update which would fail. Now I could provide some kind of options API, but the problem is that since the user is using standard POJO calls it is not always clear what such an operation involves. -Jason View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4056716#...
