[jira] [Commented] (SCB-268) [pack] compact events to remove
unnecessary fields
[ https://issues.apache.org/jira/browse/SCB-268?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16577788#comment-16577788 ]
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.
