Iceberg: a fast table format for S3

Tuesday, June 19
11:50 AM - 12:30 PM
Meeting Room 211A/B/C/D

Netflix’s Big Data Platform team manages data warehouse in Amazon S3 with over 60 petabytes of data and writes hundreds of terabytes of data every day. With a data warehouse at this scale, it is a constant challenge to keep improving performance. This talk will focus on Iceberg, a new table metadata format that is designed for managing huge tables backed by S3 storage. Iceberg decreases job planning time from minutes to under a second, while also isolating reads from writes to guarantee jobs always use consistent table snapshots.

In this session, you'll learn:
• Some background about big data at Netflix
• Why Iceberg is needed and the drawbacks of the current tables used by Spark and Hive
• How Iceberg maintains table metadata to make queries fast and reliable
• The benefits of Iceberg's design and how it is changing the way Netflix manages its data warehouse
• How you can get started using Iceberg
