Core Learning Objectives
- 1.Visually map in-memory data structures to physical NVMe storage persistence.
- 2.Trace transactional commit handshakes across HANA System Replication topologies.
- 3.Understand MDC tenant isolation and internal communication buses.
- 4.Review end-to-end disaster recovery failover and recovery sequences.

Definition & Architectural Rationale
Technical Definition:
Visual architecture representations of SAP HANA runtime engines, thread pools, persistence loops, and distributed cluster nodes using Mermaid diagrams.
Why this component exists:
Complex multi-process distributed systems are difficult to grasp purely through textual documentation. Clear architectural diagrams accelerate concept retention, system design reasoning, and interview mastery.
Internal Working & Mechanics
This module acts as an interactive visual directory providing interactive, zoomable, copyable Mermaid diagrams with accompanying structural explanations, dependency breakdowns, and failure mode analysis.

Architectural Flow: SQL statements enter via client ports, are parsed, optimized by the Cost-Based Optimizer, checked against SQL Plan Cache, and executed by specialized vector engines before persistence logging.
Production Best Practices & Operational Risks
Mandatory Best Practices
- Use Plan Visualizer (PlanViz) in SAP HANA Cockpit to visualize real query execution graphs when diagnosing slow reports.
- Refer to these visual maps when explaining architectural decisions during senior DBA interviews.
