Features

• Cloud-Native Frameworks - Provides a Java framework optimized for containerized and serverless cloud environments with native compilation support.
• CDI and JAX-RS Implementations - Implements standard Java enterprise specifications, specifically CDI and JAX-RS, to ensure microservice interoperability.
• Native AOT Compilation - Converts Java applications into small-footprint native binaries to significantly reduce startup time and memory usage.
• Observability API Standards - Applies a consistent set of standardized APIs for telemetry and core profiles to ensure service interoperability.
• Multi-Protocol Support - Provides multi-protocol support enabling the delivery of data through REST, GraphQL, and gRPC interfaces.
• Ahead-Of-Time Compilation - Transforms Java bytecode into standalone machine code binaries to minimize startup time and memory overhead.
• Virtual Thread Executors - Utilizes virtual thread executors to map each connection to a lightweight Java virtual thread for high-volume concurrency.
• Web Server Virtual Threading - Ships a high-performance web server that uses Java virtual threads to handle high-volume concurrent requests.
• Cloud-Native Java Frameworks - Provides a comprehensive Java framework for building cloud-native applications with functional-reactive programming support.
• Unified Observability Interfaces - Implements unified observability interfaces for integrating health checks, metrics, and tracing across distributed environments.
• Service Observability Integrations - Integrates standardized health checks, metrics, and distributed tracing for monitoring service reliability in clusters.
• HTTP Request Handling - Provides high-performance HTTP request handling utilizing Java virtual threads to process high volumes of concurrent traffic.
• High-Performance HTTP Servers - Implements a high-performance HTTP server utilizing virtual threads for high-throughput and low-latency request handling.
• HTTP Request Routing - Implements a routing system that maps incoming network paths to specific service handlers based on predefined patterns.
• Application Project Bootstrapping - Offers a CLI and predefined archetypes for generating the initial structure and dependencies of new applications.
• Global Configurations - Centralizes framework-wide system settings using a single global configuration instance accessible application-wide.
• Standalone Binaries - Generates standalone native binary executables from Java bytecode to minimize startup time and memory footprint.
• Project Lifecycle Management Tools - Provides command-line tools to automate the generation, building, and continuous development lifecycle of applications.
• API Gateway - Functions as an API gateway that maps requests to multiple backend service protocols like REST, GraphQL, and gRPC.
• Hierarchical Configuration Systems - Provides a hierarchical configuration system that resolves settings across multiple nested sources into a single instance.
• Automatic Dependency Discovery - Automatically discovers and registers server extensions and features based on dependencies present on the classpath.
• Functional Reactive Programming Frameworks - Implements a functional-reactive programming model to process asynchronous data streams and maintain high throughput.
• Classpath Service Discovery - Automatically detects and registers server features and extensions by scanning the application classpath at runtime.
• Reactive & Messaging - Supports reactive messaging and streams to manage asynchronous data flow and communication between independent microservices.
• Microservice Management CLIs - Automates the setup and management of microservice components across different operating systems via a dedicated CLI.
• Multi-Protocol API Design - Supports multi-protocol API design by exposing service data through REST, GraphQL, and gRPC.
