Medallion Architecture Layers
Scenario context
Decoupled system architecture isolating ingress, stateless logic, and persistent datastores.
🎯 System Scenario & Requirements
System Goal
Decoupled system architecture isolating ingress, stateless logic, and persistent datastores.
Actors & Components
- Edge Traffic Ingress
- Stateless Microservices
- Datastore Infrastructure
- API Gateway
- Domain Service
- Redis Cache
- Transactional DB
Functional Requirements
- Decoupled system architecture isolating ingress, stateless logic, and persistent datastores.
- The system topology organizes components across groups: Edge Traffic Ingress, Stateless Microservices, Datastore Infrastructure.
- Each component maintains isolated responsibilities to protect system throughput.
Constraints & Assumptions
- The source does not isolate a separate failure mode.
- Limits that matter for the scenario are called out in the stage decisions above.
⚡ Execution Stages & Decision Trace
Stage 1 — Stage 1 — Data Flow & Inter-Service Invariants
- Stateless compute nodes scale horizontally while shielding underlying database clusters behind fast cache layers.
Applies data-warehousing-lakehouse to the decision above.
