Question

I would like to implement a distinct thread for each route in apache camel.I do not want to use a thread pool or async as I want my process to remain synchronous.Could I please get a code example for the same in java DSL format.

Answer 1

Each route uses its own thread, unless a route is using the direct component (http://camel.apache.org/direct), which will re-use the caller thread.

For example having 2 routes

from("file:foo").to("bean:blah");
from("jms:queue:bar").to("bean:great")

Is 2 routes, and each route uses its own thread.

On the other hand the following 2 routes

from("file:foo").to("bean:blah").to("direct:bar");
from("direct:bar").to("bean:great")

Then the 2nd route being a direct endpoint, will re-use the caller thread, from the 1st route, when the 1st route routes the message to it, using: .to(“direct:bar”)
