FSI304: Nasdaq: From data warehouse to data lake

Earlier this year, Nasdaq embarked on a strategy to migrate its growing 68-node Amazon Redshift data warehouse to a more modern data lake architecture with the goal of better managing expenses and taking advantage of additional analytical services. In this session, we share the path Nasdaq took, what worked well, what challenges we encountered, and how and why we had to rewrite queries and rethink our initial strategy. In completing this migration, Nasdaq reduced the cost of its existing data warehouse environment while providing a more cost-effective, scalable, and elastic platform to its business.
