Apache Camel - What is SEDA? How can I add concurrency in SEDA? (8/250-2016)

SEDA - Staged Event Driven Architecture - breaks donw complex application into statges using internal queues - to handover messages between routes.

DIRECT - is similar to SEDA component - but it is fully synchronized and acts as a direct call.

Ex.

from("file:\\...")
.to("seda:test")
...

from("seda:test?concurrentConsumers=20")
....
....


In this case -  20 threads will be created and the processing will be fast.
