The challenge

What was in the way

A leading retail bank in the UK was looking to modernize its data warehousing capabilities and consolidate multiple fragmented data sources into a single, scalable lakehouse platform.

  • 01
    Regulatory & compliance pressure

    Strict data governance requirements that any new platform had to satisfy from day one, not retrofit later.

  • 02
    Rapidly growing data volumes

    Transactional, customer and operational data growing exponentially against a warehouse that scaled by procurement.

  • 03
    Operational complexity

    Legacy systems required high manual intervention, with failed jobs needing someone to notice and rerun them.

  • 04
    High cost of change

    Traditional data warehouse enhancements were time-consuming, making every new source a project of its own.

Our solution

What we built

We designed and implemented an Azure-based metadata-driven lakehouse that addressed both the immediate operational pain points and the bank's long-term scalability goals.

01

Fully Metadata-Driven Architecture

New data sources are onboarded by adding metadata configurations rather than writing bespoke pipelines, reducing development from weeks to days.

02

Automated Failure Recovery

Intelligent monitoring with automatic detection and reprocessing of failed jobs, without manual intervention or an engineer on call.

03

Cost-Optimized Design

Azure's tiered storage and elastic compute used deliberately, holding performance targets while staying inside budget.

04

Governance Carried Through

Lineage, access control and audit evidence built into the platform itself, so compliance is a property of the system rather than a reporting exercise.

Impact & results

What changed

Faster onboarding

New datasets moved from weeks to days.

Cost reduction

Significant infrastructure and operational savings against the legacy estate.

Full compliance

Meeting all financial industry standards.
