Metadata Management And Integration At LinkedIn With DataHub

Audio version of the article

SummaryIn order to scale the use of data across an organization there are a number of challenges related to discovery, governance, and integration that need to be solved. The key to those solutions is a robust and flexible metadata management system. LinkedIn has gone through several iterations on the most maintainable and scalable approach to metadata, leading them to their current work on DataHub. In this episode Mars Lan and Pardhu Gunnam explain how they designed the platform, how it integrates into their data platforms, and how it is being used to power data discovery and analytics at LinkedIn.

The need for quality customer data across the entire organization has never been greater, but data engineers on the ground know that building a scalable pipeline and securely distributing that data across the company is no small task. Customer data platforms can help automate the process, but most have broken MTU pricing models or cloud security issues. RudderStack is the answer to those customer data infrastructure problems. Our open source data capture and routing solutions help you turn your own warehouse into a secure customer data platform and our fixed-fee pricing means you never have to worry about unexpected costs from spikes in volume.
