It would probably be more dependent on
your messaging system, and what you decide to configure. I think
you’re probably on the right track with dividing your topics in such a
way that they’ll be more efficient in what data gets pushed regularly so
that a client can better optimize their experience.

Enterprise Server 2.0
Hi all,
I was at the Macromedia Max 2005 in Hong Kong and got a 'taste' of the new
Enterprise Services in 2.0.
One of the interesting things is the messaging
service and the ability to
push data to the client. The issue I have is that
if it is using the
traditional sense of publishing data to be
listened to, how does such a
feature deal with potentially large amount of data
such as the stock market
information?
In a 'real time' scenario, stock market
information is being published at
very short intervals and transactions can be heavy
depending on market and
specific stocks. On the face of it, this seems
like the best scenario for
such a messaging feature.
If we publish all stock information, then it seems
like the client will have
to manage the data that it wants to display. This
could be expensive for the
client.
Maybe we divide the channels up so that different
information (different
markets) are published on different channels? This
could reduce some of the
workload for the client.
In any case, if a market has thousands of stocks,
then the client would
still need to do a lot of expensive processing.
The question is:
Is there someway for the publisher to recognise
different listeners and
publish accordingly? Theorectically, this should
be an acceptable way of
publishing data... But can someone tell me if this
would be possible with
the upcoming Enterprise Services? Or does this all
depend on the
implementation of the messaging system (e.g. JMS,
MQ etc)?
Thanks,
Kam.
