Hi all,
I would like to know what are the real differences between ONE_PHASE
and TWO_PHASES operations (create, update,delete,etc…).
In detail I’ve looked through update function of ConnectorFacadeProxy
class and I’ve not understood which are differences.
It seems in every case it calls in async mode, is it right?
Hi Nicola,
as you can rad from [1], ONE_PHASE means that propagation is an atomic
operation: Syncope calls the external resource and expects an immediate
result.
Conversely, TWO_PHASES means that Syncope calls the external resource
and returns immediately. Later, when the propagation has completed, the
external resource will notify the actual propagation result to Syncope.
Hope this clarifies.
Regards.
