Can i use seda:start or direct:start to start a route?

[gudiseashok <gu...@gmail.com>]

Hi 

Sorry to be silly with my question but i would like to know whether
inter-communication components like seda/direct to kick start my routers, I
do have configured ActiveMQ also but I didn't find any justification myself
to kickstart only with MQ when I need to start some routers (load on
startup) and doesnt need any from any consumer.

So, suppose I have three routers A,B,C

I would like to know, whether is it a right approach to do like mentioned
below,

from("seda:start").multicast().parallelProcessing().to("direct:a","direct:b","direct:c");

from("direct:a").from("remoteFTP1:///")
						.routeId("ftpRoute1").to("file://{{sftp.destination.directory}}");
from("direct:b").from("remoteFTP2:///")
						.routeId("ftpRoute2").to("file://{{sftp.destination.directory}}");
from("direct:b").from("remoteFTP3:///")
						.routeId("ftpRoute3").to("file://{{sftp.destination.directory}}");

Because I read like "direct:XXX" is for synchronous communication but
multicast/parallel prosessing will be depricated in near future, 

but "seda:XXX" for asynchronous but we can configure this to act as
synchronous and can be used for operations like "fire and forget" with added
advantage of parallelprocessing with concurrentconsumer attribute.

I see lot of examples using from("seda:start,direct:start... and it is
working for me in my local, but most of the stuff being using either using
activeMQ or external end point.

Is it right way of doing to kick start (just to use loadOnstartup) using
"seda:start" or "direct:start" (I would like to use "seda:start",since its
been written it supports concurrent operation)

Ashok Gudise

Hi Thanks for reply, I will change accordingly

adding to my previous question,

RouteBuilder routeBuilder = new RouteBuilder() {
	@Override
	public void configure() throws Exception {

		from("seda:start").routeId("mainRoute")
		.multicast().parallelProcessing().to("direct:a","direct:b");

		from("direct:a").from("sftp://ftp1)
			.routeId("helloRoute1").to("file://{{sftp.destination.directory}}");
		from("direct:b").from("sftp://ftp2)
			.routeId("helloRoute2").to("file://{{sftp.destination.directory}}");
	}
};

Thread.sleep(6000); //Wait for a minute

RouteBuilder routeBuilder1 = new RouteBuilder() {
	@Override
	public void configure() throws Exception {
		from("direct:c").from("sftp://ftp3")
		.routeId("helloRoute3").to("file://{{sftp.destination.directory}}");

	}
};
camelContext.addRoutes(routeBuilder1);
Thread.sleep(500000);

------------ Does this equal to 
<from uri="seda:start"/>
<multicast>
   <to uri="direct:a"/>
   <to uri="direct:a"/>
<multicast>

when I add <direct:c> like above 

<from uri="seda:start"/>
<multicast>
   <to uri="direct:a"/>
   <to uri="direct:a"/>
   <to uri="direct:c"/>
<multicast>  (does the above code converts like this?, because I want to add
another router which is similar to what I have added as parallel to those
already started processes).


Thanks you very much for your response.

[Christian Posta <ch...@gmail.com>]

well, it's fine to kick off routes with direct or seda.
however what are you expecting your second route to do? poll the FTP
location? when you have from(a).from(b).to(...) you basically have two
separate entry points to your route: from(a) and from(b). so if you're
trying to kick of something to call FTP, change the from(remoteFTP) to use
pollEnrich().
