🏗️ Project Structure

🎯 Core Features
Real-Time Data Streaming
Kafka Producer: Simulates live stock market data feeds with randomized sampling
Distributed Processing: Multi-broker Kafka cluster for high availability
Consumer Groups: Scalable data consumption with automatic load balancing
AWS Data Storage & Management
S3 Bucket Architecture: Created S3 bucket for storing streaming stock market data
File-per-Event Storage: Each consumed message stored as individual JSON file in S3 for granular data management
Automated Data Organization: Structured file naming convention (stock-market-json-1.json, stock-market-json-2.json, etc.)
Data Catalog & Schema Management
AWS Glue Crawler: Automated crawler setup to scan S3 bucket and detect data schemas
Database Creation: Established dedicated database in AWS Glue for data catalog management
Schema Evolution: Automatic schema detection and catalog updates as new data arrives
Metadata Management: Centralized catalog enabling seamless data discovery and querying
Real-Time Analytics Infrastructure
Amazon Athena Integration: SQL-based querying directly on S3-stored JSON files
Serverless Analytics: No infrastructure management for query processing
Real-Time Query Capability: Instant analytics on streaming data with sub-second latency
Scalable Query Performance: Handle concurrent analytical workloads without performance degradation
End-to-End Automation
Seamless Data Pipeline: Automatic flow from Kafka → Consumer → S3 → Glue Catalog → Athena
No Manual Schema Definition: Crawler automatically infers JSON structure and creates queryable tables
Real-Time Data Availability: New data immediately queryable through Athena after S3 upload
✨ Business Impact
Problem Solved: Traditional batch processing creates delays in financial data analysis, missing critical market opportunities.
Solution: Real-time streaming architecture enables instant data processing and analysis, supporting:
High-frequency trading decisions
Risk management alerts
Market trend detection
Regulatory compliance reporting
📊 Technical Achievements
