Back to Basics : Apache Camel Routes and Direct Component

Question

I am bit confused about Camel routes and its two endpoints : Direct and Seda. Well let\'s say i have a route like this :

public void configure()
{
 from(\"di         


        

Answer 1

The direct component runs in the thread of the caller. Simplified, it's as a regular java method invocation. Multiple messages can run through the route as long as multiple threads are calling the direct endpoint.

When invoking the SEDA (or VM) endpoint, you message is put on a queue (in memory). Another thread (in the route) picks messages from the queue one by one and processes them. You can configure how many threads the seda consumer should have by setting the concurrentConsumers option. By default, the one thread consuming messages makes sure only one message at a time is processed no matter how many threads are producing to this route.

It boils down to your statement

in a instant I send multiple different messages to this route

If this means different threads, or just from one single thread in a sequence,
