Alan,
Thanks for putting this together. First some questions:
* is this meant to do a one-time sync? or provide ongoing
synchronization between two event servers? I think your primary use case
is syncing state between a primary and backup, in which case it would
seem to me you'd need this on an ongoing basis, no?
* Assuming the primary use case is syncing state between a primary and
backup, these batch notifications don't seem sufficient to make that
work. In the case of presence, you really need the input states to the
compositor - whatever they are - in order to allow the backup to
continue to compute the presence state. Similarly, in the case of
conferencing state, the conference itself would need to move to the
backup in order for the backup to continue to generate event state. If
you've moved the conference over anyway, the backup has the state it
needs to generate the event notifications. So I don't see what is served
by the batch notifications.
* is the assumption that the subscription is to ALL state? Or do you
intend that the body of the subscribe could contain, for example, a list
of the URI for which state is desired?
And a comment:
* the example shows the server terminating the subscription when it is
'done'. However, the state may have changed since it was sent to the
backup. Seems you have the 'catch the running train problem' of database
state sync and you'd need to continuously keep the subscription going.
Thanks,
Jonathan R.
