Willem Jiang updated SCB-836:
-----------------------------
Description:
We can take the
[nesting-lras|https://github.com/eclipse/microprofile-lra/blob/master/spec/src/main/asciidoc/microprofile-lra-spec.adoc#323-nesting-lras]
from the microprofile as an example.
An activity can be scoped within an existing Saga using the @NestedSaga
annotation. Invoking a method marked with this annotation will start a new Saga
whose outcome depends upon whether the enclosing Saga is closed or cancelled.
* If the nested Saga is closed but the outer Saga is cancelled then the
participants registered with the nested Saga will be told to compensate.
* If the nested Saga is cancelled the outer Saga can be still closed.
> Support the nesting SagaStart
