             Summary: Define a saga DSL and implementation for long running

                 Key: CAMEL-11665
                 URL: https://issues.apache.org/jira/browse/CAMEL-11665
             Project: Camel
          Issue Type: New Feature
          Components: camel-core
            Reporter: Nicola Ferraro

I'm trying to define a saga interface and DSL for Camel in order to support 
long running actions.

I've done some experiments here: 
https://github.com/nicolaferraro/camel/blob/8ad4a4a264bbcd882507893e810a65578253caa4/camel-core/src/test/java/org/apache/camel/processor/SagaTest.java#L102-L146

The experiment works with a in memory saga manager.
It should be possible to switch to a proper "long running action coordinator" 
(e.g. the one proposed here 
https://github.com/jbosstm/microprofile-sandbox/blob/0009-LRA/proposals/0009-LRA/0009-LRA.md)
 once an implementation is ready.

We can also think to provide our own implementation based on a shared 
transaction log, but it will be a "hard" task and it would not be compatible 
with other languages/frameworks, so the "spec" way should be preferable.
