Our docs are 100% public and free to view. You just need to register. You got similar behavior with many other software vendors. Not sure "I want to be notified, if there is an entry for a yellow knife AND an entry for a blue fork" Hmmm - Not a trivial request. See our multicast notifications support with its filter s capability: http://www.gigaspaces.com/docs/cache/Multicast_Notifications.htm \GigaSpaces4.1\examples\Getting_Started\multicast-notify Shay -----Original Message----- From: Stefan Schulz [mailto:[email protected]] Sent: Saturday, December 03, 2005 9:56 PM To: [email protected] Subject: Re: entry ordering for blackboard-style communication? Hi Shay, thanks for the reply. Unfortunately, the document links require registration at GigaSpaces. Also it seems to be free, I am not sure if this is the right way to provide information ;) Shay Hassidim wrote: > The Space SQL query API allows you to query one class instances.

It would be rather interesting to know, if it is possible to have complex conditionals with SQL in GigaSpaces, e.g., to register for notification on the existence of more than one (kind of) entry, comparable to SQL JOIN. For example: "I want to be notified, if there is an entry for a yellow knife AND an entry for a blue fork". :) Cheers, Stefan =========================================================================== To unsubscribe, send email to [email protected] and include in the body of the message "signoff JAVASPACES-USERS".
