Kurt T Stam commented on JUDDI-423:
-----------------------------------
We intend to only send out notification when there are changes; just like the
'find_service notifications' behavior you describe. So you will receive one
update. Not one with each interval. So there seems to be a bug here. It'd be
great if you can attach a test, so we reproduce it. We currently getting ready
for a 3.0.4 release and it would be nice to fix this.
Interesting to hear that other products send out the notification with each
interval. That could lead to a lot of useless communication. I think we
envision a situation where the interval can be quite small, so you get near
'real-time' updates of services change.
Thx,

> Components: core
> Affects Versions: 3.0.3

> When using any asynchronous subscription using a filter other than
> find_service notifications are sent regularly at the specified
> notifcationInterval regardless of whether or not there is actually a change
> to the applicable entities. This is not the case when using a find_service
> subscriptionFilter, notifications are only sent when changes are made to the
> applicable entities. Which of these is the intended behavior? The
> specification is vague on this issue, stating in one place that "When
> asynchronous notifications are requested, subscriptions provide information
> on new, changed or deleted entities within a registry that occur after the
> point in time that the subscription is registered" (Section 5.5.1) but states
> that notificationIntervals "specifies how often change notifications are to
> be provided to a subscriber." (Section 5.5.8.2). Other products tend to
> follow the model jUDDI follows when using a non find_service filter (i.e.
> sending a notification at every notificationInterval).
