event driven architecture microservices

. A second challenge is how to search for data from multiple services. For example, imagine that an app needs to show customers and his orders. If the order service provides an API to accept user order information, the user can receive data using a class-applied join operation. The app accepts user information from the User Service and accepts this user order from the order service. Assuming that the order service only supports querying orders via private key (key) (perhaps using a NoSQL databa

to trace eventsEvent traceability is a special idea for us, he does not persist the entity object, but only the initial state and the event of each change is recorded, and in memory based on the event to restore the entity object's latest state, the implementation is similar to the implementation of database Redolog, It's just that he put this mechanism into the application layer.Although the traceability

For a long time, I've been thinking about how to implement a complete set of event-driven architectures in the framework of ASP. The problem looks a bit big, but the main goal is to implement an ASP. NET core-based microservices that can easily subscribe to event messages from a channel and process the received message

In actual use, may also encounter some problems related to RABBITMQ it

The following is an excerpt from his original words: "Is the current SOA, ESB, and other things like building a" neural context "of an enterprise, and" OO "like" neurons ", communication between them relies on biological electric pulse, which is message-driven." Therefore, I

This paper introduces the application of Enode frame to staged event-driven architecture thought. We know from the previous article that command service is highly concurrent access, and we can improve system response performance in addition to executing command

Event-driven: trigger an event and then call the relevant available resources to solve the event.Asynchronous: you do not need to wait for the return value of the called function to make the next call.I/O: Short for input/output, that is, the input/output port.First, node is an architecture that serves I/O through
