System Motivation

[cite_start]Modern systems live or die by their data flow. While managed solutions like Kafka or RabbitMQ exist, true system design mastery requires understanding the mechanics under the hood: partitioning, coordination, fault tolerance, and backpressure[cite: 16].

System Topology

ARCHITECTURE SPLIT: INFRASTRUCTURE vs APPLICATION LAYERS

1. Message Broker (mini-Kafka)

[cite_start]A simplified Kafka-like system implemented to reason about distributed log internals[cite: 18].

  • Topic & Partition Management

  • Sequential vs. Concurrent I/O

  • Broker Coordination

2. Real-Time Streaming Pipeline

[cite_start]A practical alerting application demonstrating how infrastructure supports real-time decisions[cite: 19].

  • Async Event Processing

  • Condition-based Alerting

  • Persistent Storage

Engineering Kernels

Event-Driven Architecture

Producers and consumers are strictly decoupled via topics. [cite_start]This separation allows independent scaling of ingestion and processing layers[cite: 16].

Ordering & Consistency

[cite_start]Investigated how partition-level ordering guarantees function and the trade-offs involved in maintaining total vs. causal ordering[cite: 16].

Fault Awareness

The system assumes failure is inevitable. [cite_start]Components are designed to recover cleanly from broker crashes or network partitions without data corruption[cite: 16].

Backpressure & Lag

[cite_start]Evaluated system stability when producer ingestion rates exceed consumer processing capabilities, ensuring the system degrades gracefully[cite: 16].

PHILOSOPHY_LOG

This implementation prioritized conceptual clarity and correctness over full protocol compatibility or raw throughput. The goal was observability: ensuring system behavior under load could be reasoned about and debugged effectively.
