Exploring Apache Iceberg: A Modern Data Lake Stack

Abstract

Bloomberg is a leading provider of financial data, with information spanning multiple decades. Handling and organizing these huge datasets can be challenging, with typical concerns including sluggish query performance, high storage costs, and data consistency problems. This talk will describe how Apache Iceberg is revolutionizing big data management, offering ACID transactions, time travel, and seamless schema evolution that enable lightning-fast query performance and robust data consistency for even our largest workloads. The session will introduce Apache Iceberg, an open-source table format that enables incremental updates, versioning, and schema evolution. The discussion will focus on how these features address common big data management challenges, improve query performance, and reduce storage costs. Finally, the session will outline how our Enterprise Data Lake Applications engineering team has harnessed the capabilities of Apache Iceberg (especially PyIceberg) to revolutionize our data management and analytical processing workflows. Attendees will be able to apply the best practices discussed in the talk to build better infrastructure for their growing data demands and spur innovation within their organization.
