15+ legacy data warehouses consolidated onto Snowflake
SnowflakedbtApache Kafka
Executive Summary
A tier-1 telco migrated 15+ legacy data warehouses to Snowflake, enabling real-time network performance analytics and reducing reporting latency from hours to seconds.
- Industry: Telecommunications
- Geography: India
- Capability: Data Practice Modernisation
- Technologies: Snowflake, dbt, Apache Kafka, Databricks
- Key Outcome: 15 legacy data warehouses consolidated into one platform
The Challenge
The operator's data landscape was fragmented and unmanageable. Key pain points included:
- •Fragmented analytics estate spanning 15+ legacy on-premises data warehouses
- •Reporting latency of 4–12 hours preventing real-time network management decisions
- •Significant data quality issues arising from disconnected siloed systems across teams
Delivery
Saints & Masters designed a unified data platform to replace the fragmented legacy estate:
- •Designed a unified Snowflake Data Cloud architecture to consolidate all 15 legacy source systems
- •Migrated and transformed all data sources using dbt with comprehensive data quality validation
- •Implemented real-time Apache Kafka ingestion pipelines for live network telemetry and event streams
- •Delivered a governed semantic layer in Snowflake accessible to 300+ analysts across the organisation
Results
The transformation delivered measurable excellence across the enterprise:
- •15 legacy data warehouses consolidated into one platform
- •Reporting latency reduced from hours to under 30 seconds
- •300+ analysts now working from a single governed data source
- •Real-time network fault detection enabled for the first time
- •40% reduction in data infrastructure operational costs
