In this talk I’ll go into detail about Tumblr’s experience developing Motherboy, an eventually consistent inbox style storage system built around HBase. The SLA, write concurrency, data volume, and failure modes for this application created a number of challenges in developing a solution. The user homing scheme introduced additional complexity that made capacity planning tricky as we tried to trad
Apache HBase is a rapidly-evolving random-access distributed data store built on top of Apache Hadoop's HDFS and Apache ZooKeeper. Drawing from real-world support experiences, this talk provides administrators insight into improving HBase's availability and recovering from situations where HBase is not available. We share tips on the common root causes of unavailability, explain how to diagnose th
Optimizing MapReduce job performance is often seen as something of a black art. In order to maximize performance, developers need to understand the inner workings of the MapReduce execution framework and how they are affected by various configuration parameters and MR design patterns. The talk will illustrate the underlying mechanics of job and task execution, including the map side sort/spill, th
Most developers are familiar with the topic of “database design”. In the relational world, normalization is the name of the game. How do things change when you’re working with a scalable, distributed, non-SQL database like HBase? This talk will cover the basics of HBase schema design at a high level and give several common patterns and examples of real-world schemas to solve interesting problems.

How can you rank product search results when you have very little data about how past shoppers have interacted with the products? Through large scale analysis of its clickstream data, Etsy is automatically discovering product attributes (things like materials, prices, or text features) which signal that a search result is particularly relevant (or irrelevant) to a given query. This attribute-level
The document summarizes HBase use at Facebook, including its development and future work. HBase is used for incremental updates to data warehouses, high frequency analytics, and write-intensive workloads. Development includes Hive integration, master high availability, and random read optimizations. Future work focuses on coprocessors, intelligent load balancing, and cluster performance.Read less

This document provides an overview of Hadoop and how it can be used for data consolidation, schema flexibility, and query flexibility compared to a relational database. It describes the key components of Hadoop including HDFS for storage and MapReduce for distributed processing. Examples of industry use cases are also presented, showing how Hadoop enables affordable long-term storage and scalable
