> 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
