Initial version of Compensations API ------------------------------------ Key: JBTM-1472 URL: https://issues.jboss.org/browse/JBTM-1472 Project: JBoss Transaction Manager Issue Type: Feature Request Security Level: Public(Everyone can see) Components: Transaction Core, XTS Reporter: Paul Robinson Assignee: Paul Robinson Fix For: 5.0.0.M3 Original Estimate: 2 weeks Time Spent: 1 week, 6 hours Remaining Estimate: 3 days We essentially provide a JTA-like implementation for using compensations. We would support distribution over Web services and REST via WS-BA and REST-JDI. This is similar in how we do distributed ACID transactions today; the application is developed against the JTA, but through configuration we enable distributed transactions over a particular transport (remoting, IIOP, WS). It would be good to have some subset of functionality that worked on a raw VM (i.e. no appserver). This would hopefully broaden the market. This first piece of work is to do some initial research and support an API with potentially a subset of features of the final API. Tasks: # Investigate existing WS-BA APIs ## Try code examples if possible # Produce an initial list of features that should be covered by the API # Create a simple implementation backed by WS-BA. Implementation work, to complete this issue: # Manage lifecycle of transaction via the @Compensatable annotation # Allow Compensation and Completion handlers to be registered via annotations # Mechanism for allowing application to mark the transaction as CompensateOnly # Document the API # Merge into Narayana code base # OOTB support in WildFly
