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