I'm starting to try out XmlBlaster and found that the installation is
simple, and the examples are a great help in understanding the basic
stuff to use XmlBlaster. Thanks.
I have one question though. I'm wondering whether XmlBlaster can
handle this scenario:
A and B subscribe to Server1. C publish, say 10 messages to Server1.
Instead of Server1 resend the 10 messages to both A and B, Server1
sends 5 messages to A and the other 5 to B.
Ok, sounds nice.
But what is the rule behind this scenario?
Is it load balancing, say 1,3,5,7,9 are sent to A and 2,4,6,8,10 are
sent to B?
Subscribe rules are in this case:
subscribe: A-filter = (msg.instanceCounter % 2) == 0
subscribe: B-filter = (msg.instanceCounter % 2) == 1
As there could be millions of different rules, do you have an idea
how to handle this as a generic QoS for xmlBlaster?
But there is a solution for you - our access filter plugin framework:
Write an AccessFilter plugin and filter your subscribes with any
rule you like, please read:
It is very simple to write your own plugin,
This is possible. Is there an example in XmlBlaster that I overlooked
that demonstrates this?
Any help is appreciated.
