The Pipeline FrameworkReactive Pipeline Processing

Key Features ​

The Pipeline Framework is a powerful tool for building reactive pipeline processing systems. It simplifies the development of distributed systems by providing a consistent way to create, configure, and deploy pipeline steps.

Runtime and Processing Model ​

• Reactive by default: Built on Mutiny for non-blocking throughput and backpressure-aware execution.
• Why it matters: Better CPU utilization and higher compute density typically mean lower runtime cost for the same workload.
• Quarkus runtime foundation: Aligns with Quarkus runtime and build-time patterns for fast, production-grade services.
• Immutable event flow: No in-place updates during execution; append/preserve semantics improve traceability and safety.
• Rich step semantics: Supports OneToOne, OneToMany, ManyToOne, ManyToMany, and SideEffect patterns.

Extensibility with Plugins ​

• Plugin-friendly model: Pipeline plugins add cross-cutting capabilities without coupling business logic to infrastructure code.
• Why it matters: You can deliver platform concerns (cache, telemetry, orchestration behaviors) with less code churn in core services.
• Clear extension points: Use Using Plugins and Aspect Semantics as primary references.

Integration and Deployment Flexibility ​

• Transport coverage: Automatic generation for gRPC, REST, and local/in-process clients.
• Quarkus Dev Services workflow: Smooth local development with managed service dependencies (for example, PostgreSQL) in dev/test flows.
• Why it matters: Teams can adapt interfaces to consumers and platform constraints without rewriting core processing logic.
• Deployment layouts: Works across modular, pipeline-runtime, and monolith build layouts.
• Evolution path: Start with a monolith for speed, then break into services as scale and ownership boundaries grow.

Operations ​

• Built-in observability: Metrics, tracing, and structured logging are first-class.
• Resilience features: Health checks, robust error handling, and dead-letter queue support.
• Container-first packaging: Current delivery flow supports image builds with Jib for predictable CI/CD integration.
• Native compilation path: Quarkus native builds support low cold-start and efficient resource usage where needed.
• Why it matters: Teams get faster incident diagnosis, more predictable deployments, and lower operational overhead at scale.

Developer Experience ​

• Shared common module: Central place for entity and DTO definitions used across pipeline components.
• Type safety across the pipeline: Compile-time checks catch contract drift early as steps and transports evolve.
• Why it matters: Teams get safer refactors, fewer runtime mapping errors, and faster confidence when changing domain models.
• Testability gains: Functional boundaries and generated transport layers make behavior easier to isolate and test.
• Fast onboarding and testing: Design visually with Canvas and validate behavior via Testing with Testcontainers.
