Android Event Driven Architecture. An extended architecture provides two points of integration: A producer publishes an event to the router, which filters and pushes the events to consumers.
Specifically, when an application or service performs an action or undergoes a change that another application or service might want to know about, it publishes an event —a record of that action or change—that another. It provides five key benefits to modern application. Some business transactions, however, span multiple service so you need a mechanism to ensure data consistency across services.

An event producer detects or senses an event and represents the event as a message. Each service has its own database. Events are written to a log.
Some Time Ago, I Noticed Something About Architectural Patterns Like Mvp And Mvvm That Hadn’t Occurred To Me Before:
Event producers, event channel, and event consumers. Like button presses or screen touch etc. The contracts for these patterns loosely describe state machines.
Events Can Either Carry The State (The Item Purchased, Its Price, And A.
The messaging infrastructure keeps track of subscriptions. Integration with analytics or machine learning to derive insights In android this could be done through handler and messenger, but the android style is so primitive as we have to setup too many stuff manually, there are libraries for message driven architecture.
Mvp Typically Has A One To One Mapping Between The Presenter And The View, While Mvvm Can Map Many Views To One View Model In Mvvm The View Model Has No Reference To The View, While In Mvp The View Knows The Presenter.
You have applied the database per service pattern. You get rid of the headache of adding/removing components, i.e removing subscribers without modifying publishers an so forth. Broker scaling the second point is about broker scaling.
Integration With Traditional Applications And Data Resources.
This pattern has been deprecated and replaced by the saga pattern. After an event is received, it cannot be replayed, and new subscribers do not see the event. It provides five key benefits to modern application.
