Description
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
- Merge into Narayana code base
- OOTB support in WildFly
