------------------------------
Summary: Add attribute compensationMode to @Compensable annotation
Key: SCB-1695
URL: https://issues.apache.org/jira/browse/SCB-1695
Project: Apache ServiceComb
Issue Type: Improvement
Components: Saga
Reporter: Lei Zhang
Assignee: Lei Zhang
Fix For: pack-0.6.0
Pack provides two compensation modes 'forward' and 'reverse'. Users can choose
which mode to use by configuring the retries property of @Compensable annotation
If retries == 0 then reverse otherwise forward, more detail [1].
This looks confusing, we need to define a clear attribute that represents the
mode of compensation
I suggest adding a 'mode' attribute to the @Compensable annotation, which
contains three options:
* forward
* reverse (default)
* combine (first forward then reverse)
