Motivation: Solving the Low-Code Dilemma While the market is saturated with low-code platforms, most solutions suffer from critical limitations: they operate as "black boxes," introduce significant runtime performance overhead, and lack flexibility when deep customization is required. CodeSpirit was designed to address these pain poin ...

Understanding Distributed Transactions A distributed transaction involves the coordination and management of data operations across multiple distinct nodes or databases within a distributed environment. Unlike local transactions that operate within a single database instance, distributed transactions must ensure data integrity across several ph ...

Architectural Evolution and Microservices Modern software engineering has transitioned from monolithic architectures, where all components share a single database and deployment unit, to distributed systems. While Service-Oriented Architecture (SOA) abstracted common functionalities into services, Microservices architecture refines this by brea ...

Service discovery in Eureka revolves around two primary requirements for a client: obtaining the list of service provider addresses during bootstrap and dynamically detectnig changes in the Eureka server registry. This article explores how these processes are implemented on both the client and server sides. Registry Initialization in DiscoveryC ...

System Architecture The underlying infrastructure follows a layered design typical of distributed systems, separating registration, authentication, and gateway responsibilities to ensure modularity. CI/CD Workflow Implementation Automated delivery relies on a Jenkins-based pipeline that handles source control integration, build artifacts, conta ...

Overview A microservices gateway is a system that provides centralized authentication, security control, unified logging, monitoring, and rate limiting by exposing a single entry point. Spring Cloud Gateway Workflow A client sends a request to Spring Cloud Gateway. The request is first extracted and assembled into a gateway context by HttpWeb ...

Apache Dubbo RPC Framework Overview Apache Dubbo is a high-performance RPC (Remote Procedure Call) service development framework designed to address service governance and communication challenges in microservice architectures. The framework provides multi-language SDK implementations including Java and Golang. Microservices built with Dubbo in ...

Project Architecture Overview The system adopts a microservices architecture, decomposing business capabilities into independently deployable services communicating over lightweight HTTP APIs. Each service handles its own data storage and can be developed with dedicated technology stacks. The architecture diagram splits the monolith into servic ...

The Vert.x framework facilitates high-performance asynchronous programming. When a request arrives, it is delegated to the event loop rather than blocking threads. The server dispatches the task and continues processing immediately. Once the background operation completes, the result is returned via a callback mechanism, notifying the client. T ...

Previous implementations of Spring Cloud Config typically required clients to specify the server's URL directly using spring.cloud.config.uri. This approach becomes problematic when scaling the server into a cluster, as changes to the server's IP address or load-balancing setup necessitate manual updates to every client. To align with the servi ...
