[jira] [Updated] (SCB-1695) Add attribute mode to @Compensable
annotation
[ https://issues.apache.org/jira/browse/SCB-1695?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Lei Zhang updated SCB-1695:
---------------------------
Summary: Add attribute mode to @Compensable annotation (was: Add attribute compensationMode to @Compensable annotation)
> Add attribute mode 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
> Priority: Major
> 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)
