CompensatingTransaction

Undo the work performed by a series of steps, which together define an eventually consistent operation, if one or more of the steps fail. 

When to use this pattern?  

• ONLY for operations that must be undone if they fail.  

• If possible, design your solution to avoid the complexity of requiring compensating transactions. 

Considerations  

• detect eventual consistency Failure.  

• Not easy to generalized  

• Idempotent commands  

• Infrastructure  

• Original State  

• Order of steps  

• Time-out  Retry
