Case Study: Airtel Scales Data Mesh Governance and Discovery with DataHub

Airtel scales data mesh across 30+ petabytes with DataHub

The telecommunications company Airtel faced scaling challenges with its centralized data lake as volumes grew beyond 30 petabytes, slowing innovation and making governance difficult. To enable a shift to a scalable, decentralized data mesh architecture, they implemented DataHub as their metadata management backbone.

DataHub provided the solution by becoming the mandatory governance foundation, requiring cataloging for all data ingestion and tracking lineage and quality. This allowed Airtel to operationalize its data-as-a-product model securely at scale. The measurable impact included a successful transformation to a data mesh serving over 30 petabytes across 10,000+ daily jobs, with improved data discovery, streamlined quality checks, and secure, tag-based access control.
