Running heavy analytical reports directly on your primary transactional production database can lock tables, spike CPU utilization, and cause severe user-facing application timeouts.

A modern enterprise analytical architecture extracts transactional data asynchronously using Debezium and CDC (Change Data Capture), streaming records into columnar analytical databases like ClickHouse.

Columnar storage engines compress data by up to 80% and query aggregated metrics across hundreds of millions of rows in single-digit milliseconds.

AVELIO designs enterprise analytical pipelines that give executive leadership real-time business intelligence dashboards without impacting operational transactional databases.

Key Architectural Takeaway

Investing in clean modular architecture, automated CI/CD pipelines, and rigorous security audits early eliminates up to 60% of downstream maintenance costs while positioning your business for rapid international scale.
