In the last few years, Netflix’s S3 data warehouse has grown to more than 100 PB. In that time, the company has shared several techniques and released open source tools for working around S3’s quirks, including s3mper to work around eventual consistency, S3 multipart committers to commit data without renames, and the batchid pattern for cross-partition atomic commits. Ryan Blue and Daniel Weeks share lessons learned, the tools Netflix currently uses and those it has retired, and the improvements it is rolling out, including Iceberg, a new table format for S3 that is replacing many of the company’s current tools. Iceberg enables a new generation of improvements, including: * Snapshot isolation with no directory listing or file renames * Distributed planning to relieve metastore bottlenecks * Improved data layout for S3 performance * Immediately available writes from streaming applications * Opportunistic compaction and data optimization]]>

Hive tables are an integral part of the big data ecosystem, but the simple directory-based design that made them ubiquitous is increasingly problematic. Netflix uses tables backed by S3 that, like other object stores, don’t fit this directory-based model: listings are much slower, renames are not atomic, and results are eventually consistent. Even tables in HDFS are problematic at scale, and reliable query behavior requires readers to acquire locks and wait. Owen O’Malley and Ryan Blue offer an overview of Iceberg, a new open source project that defines a new table layout addresses the challenges of current Hive tables, with properties specifically designed for cloud object stores, such as S3. Iceberg is an Apache-licensed open source project. It specifies the portable table format and standardizes many important features, including: * All reads use snapshot isolation without locking. * No directory listings are required for query planning. * Files can be added, removed, or replaced atomically. * Full schema evolution supports changes in the table over time. * Partitioning evolution enables changes to the physical layout without breaking existing queries. * Data files are stored as Avro, ORC, or Parquet. * Support for Spark, Pig, and Presto.]]>

Ryan Blue explains how Netflix is building on Parquet to enhance its 40+ petabyte warehouse, combining Parquet’s features with Presto and Spark to boost ETL and interactive queries. Information about tuning Parquet is hard to find. Ryan shares what he’s learned, creating the missing guide you need. Topics include: * The tools and techniques Netflix uses to analyze Parquet tables * How to spot common problems * Recommendations for Parquet configuration settings to get the best performance out of your processing platform * The impact of this work in speeding up applications like Netflix’s telemetry service and A/B testing platform]]>
