Willem Jiang commented on SCB-268:
----------------------------------
In the [micro-profile
LRA|https://github.com/eclipse/microprofile-lra/blob/master/spec/src/main/asciidoc/microprofile-lra-spec.adoc#322-compensating-activities],
it just use the LRA reference id as the parameters for the participate to do
the compensation work.
Now we can do the same thing with the help of SCB-785 to reduce the efforts
between the omega and alpha.
Using the Global transaction ID and Local transaction ID or（LRA） with the
local service persistent store can help us find out the context for recovery or
retry.
