So, after reading some documentation and getting a lot of help from you guys
here, I finally implemented a recipient list that choose the endpoints
dynamically (a dynamic recipient list):
http://camel.apache.org/recipient-list.html
http://camel.apache.org/recipientlist-annotation.html
In my code, MainApp_A generates reports every 10 seconds, and I want it to
send the reports to all the servers at the same time, instead of doing it
one by one. Thus I have developed the following route.
//MainApp_A
main.addRouteBuilder(new RouteBuilder(){
@Override
public void configure() throws Exception {
from("direct:start").multicast().parallelProcessing()
.beanRef("recipientListBean", "route").end()
.log("${body}");
}
});
//RecipientListBean
@RecipientList
public Set<String> route(String body) {
return servers; //returns a collection of several severs
}
-----
I also checked the documentation for the Multicast pattern and the Dynamic
route:
http://camel.apache.org/multicast.html
http://camel.apache.org/dynamic-router.html
Now I have a few questions and I am confused. So I have a few questions:
1 - Is the recipient dynamic list simply the junction of the Multicast
pattern with the Dynamic Route Pattern?
2 - the multicast() call alone is purely sequential right? What is the
difference between using multicast() and recipientList()?
3 - For both multicast() and recipientList() to be concorrent I have to use
parallelProcessing(). In my case, which is more efficient?
