Project Name
How Ksolves Unified Distributed Store Data into a Scalable Global Lakehouse
The client is a major retail conglomerate operating 200+ hypermarkets across the Middle East, Asia, and beyond. As a global retail leader, it generates massive volumes of transaction and inventory data daily. This project establishes a unified, sovereign data platform to consolidate data from distributed regional sites into a centralized Lakehouse, enabling real-time analytics for multi-regional management.
- Secure Global Ingestion: Protecting sensitive POS (Point of Sale) data transfers from hundreds of geographically dispersed stores into a central hub.
- Edge Transformation: Cleaning "noisy" store logs (handling local taxes, currencies, and SKUs) before they transit to avoid central hub congestion.
- ACID Compliance at Scale: Ensuring transaction integrity for millions of daily sales records where partial writes would lead to inaccurate financial reporting.
- Regional Data Sovereignty: Maintaining strict multi-tenant isolation so regional managers see only their respective branch data within a shared central dashboard.
- Intelligent Edge Processing: Apache NiFi is deployed at each store to perform initial filtering and standardization of raw POS data. This "Edge Intelligence" reduces data volume by 30% before pushing it to the Central Kafka Cluster.
- Real-time Lakehouse Transition: Spark Streaming consumes the cleaned Kafka topics and writes them directly into Apache Iceberg tables. By using Iceberg over traditional formats, the system gains "Time Travel" capabilities (allowing it to audit inventory states at any historical timestamp).
- High-Performance Querying: Trino serves as the federated engine, querying the data on MinIO with sub-second latency. This eliminates the need to move data into a separate data warehouse.
- Unified Visualization: Apache Superset connects via Trino to provide real-time dashboards. Keycloak integration ensures that SSO is seamless and data access is governed by user roles.
- Operational Agility: NiFi Registry allows the central IT team to push new pricing or tax logic updates to all 200+ stores in seconds.
- Financial Accuracy: Apache Iceberg’s ACID transactions ensure that financial data is 100% consistent, even during network flickers or peak holiday sales.
- Cost Efficiency: Using MinIO on-premises provides a high-performance storage layer at a fraction of the cost of legacy enterprise warehouses.
- Real-time Visibility: Time-to-insight dropped from 24 hours (legacy batch) to under 60 seconds, enabling instant stock-out alerts.
MODERN DATA LAKEHOUSE ARCHITECTURE STACK
The Modern Data Lakehouse successfully bridges the gap between massive edge-scale operations and centralized corporate intelligence. By transitioning from a legacy siloed model to an Iceberg-on-MinIO architecture, the client has achieved a production-ready, highly available platform. This implementation reflects Ksolves’ expertise in building a modern data lakehouse architecture, combining warehouse-grade performance with lake flexibility for global enterprises. This setup provides the performance of a data warehouse with the flexibility of a data lake, ensuring the client remains data-driven as it expands into new global markets.
