Message Flow (Magic xpi 4.1)
Magic xpi engines communicate with the Space through a GigaSpaces proxy, which is a software module that connects client applications to the Space.
Each Magic xpi engine can run flow threads and trigger threads. In addition, there are external triggers running in other process Spaces, such as the HTTP trigger or the Web Services trigger.
Triggers create new flow invocation request messages that are handled by workers, either synchronously or asynchronously.
