Implementing Domain-Driven Design

Distributed Processing

A powerful use of a Data Fabric is to distribute processing across the Fabric’s replicated caches and return the aggregated results to the client. This enables the Fabric to fulfill Event-Driven, distributed parallel processing, perhaps using Long-Running Processes.

To illustrate this feature, we’ll have to mention some concrete approaches in GemFire and Coherence. Your Process executive could be implemented as a GemFire Function or a Coherence Entry Processor. Both can serve as Command [Gamma et al.] handlers that execute in parallel across distributed, replicated cache. (You might instead choose to think of this concept as a Domain Service, but what it does may not be domain-centric.) For consistency let’s call this feature ...
