Aevum News — Data Flow Architecture

System Overview

End-to-End Data Pipeline

📡

Sources

APIs, RSS, wire services, journalist submissions, IoT sensors

🌐

Ingestion

Kafka streams, message queues, rate limiting, deduplication

🔍

Validation

Schema checks, NLP fact-crossing, plagiarism detection, source verification

⚙️

Processing

Metadata tagging, AI summarization, translation, media transcoding

💾

Storage

PostgreSQL, S3/COS, Redis cache, Elasticsearch index

📤

Distribution

CDN, API gateway, webhooks, mobile push, partner feeds

📡 Ingestion Layer

All content enters through standardized protocols. We support REST, GraphQL, WebSub, and raw TCP streams for real-time data.

Idempotency keys prevent duplicate ingestion
Rate limits: 10k events/sec per source
Automatic retry with exponential backoff

🔍 Validation & Enrichment

Multi-stage verification pipeline ensures data integrity before publication routing.

JSON Schema validation (draft-07)
NLP entity resolution against knowledge graph
Media fingerprinting & hash verification

⚙️ Processing Pipeline

Parallel microservices transform raw payloads into publishable assets.

Automated captioning & metadata extraction
Multi-language translation (42 locales)
Accessibility compliance (WCAG 2.1 AA)

💾 Storage & Indexing

Hybrid storage architecture optimized for read/write patterns.

Relational: PostgreSQL (articles, authors, permissions)
Object: Global S3-compatible storage (media, archives)
Search: Elasticsearch with custom analyzers
