Speaker: Aaron Morton, Apache Cassandra Committer
Slides: http://www.slideshare.net/aaronmorton/cassandra-sf-2013-in-case-of-emergency-break-glass
The design of Apache Cassandra allows applications to provide constant uptime. Peer-to-Peer technology ensures there are no single points of failure, and the Consistency guarantees allow applications to function correctly while some nodes are down. There is also a wealth of information provided by the JMX API and the system log. All of this means that when things go wrong you have the time, information and platform to resolve them without downtime. This presentation will cover some of the common, and not so common, performance issues, failures and management tasks observed in running clusters. I'll discuss how to gather information and how to act on it. Operators, Developers and Managers will all benefit from this exposition of Cassandra in the wild.

Speakers: Michael Figuiere and Patrick McFadin, Principal Solutions Architect at DataStax
Slides: http://www.slideshare.net/planetcassandra/cassandra-summit-data-stax-java-driver
Cassandra 1.2 finalizes CQL3 and introduces a new binary protocol for client/server communication. These two components are the foundation of the new line of drivers developed by DataStax. Based on years of experience with Cassandra, these new drivers for Java, .Net and Python come with an asynchronous and lightweight architecture, a clean and simple API, a standardized way to discover nodes and to manage load balancing and fail over. This presentation will give an in depth look at these new drivers which will make your Cassandra-based applications even more robust, efficient and simple to write.

Speaker: Matt Stump, Senior Backend Engineer at KISSMetrics
Slides: http://www.slideshare.net/planetcassandra/1-matt-stump
The ability to manipulate and query very large datasets in realtime is a pressing need for most large data enterprises. Recently, we've seen an explosion of tools such as Impala or Druid, but all of these tools suffer from single points of failure or can't deliver the sub 1 second query times necessary for realtime results. Together we'll explore how to break down these seemingly intractable problems. We'll learn how to build horizontally scalable query engines with Cassandra, capable of sub-second query times across multi-billion row datasets.

Speakers: Ameet Chaubal, Technologist and Fausto Inestroza, Architect at Accenture
Slides: http://www.slideshare.net/planetcassandra/ameet-chaubal/
The presentation aims to highlight the challenges posed by large scale and near real-time data processing problems. In past, such problems were solved using conventional technologies, primarily a database and JMS queue. However these solutions had their limits and presented serious problems in terms of scale and redundancy. The new breed of products - a la Cassandra & Kafka, being innately distributed in their design, aim to tackle such challenges in a very elegant manner. The presentation will showcase some of the use cases of this genre from the industry and describe the solutions which have been increasing in their sophistication.

Speaker: Sam Heywood, Sr. Director of Products at Gazzang
Slides: http://www.slideshare.net/planetcassandra/c-summit-2013-lock-it-up-securing-sensitive-data-by-sam-heywood-23124858
As adoption of NoSQL solutions like Apache Cassandra grows, so too does the likelihood that organizations will use it to capture and analyze sensitive data. Enterprises that don't take every precaution to protect this data leave themselves exposed to risk of a data breach, and depending on the regulatory nature of the data, fines for noncompliance. This session will discuss how transparent data encryption and advanced key management protect data at-rest and in-flight, so regardless of where the data resides — either on premises or in the cloud -- it remains garbled and unreadable to all people, processes and applications that don't require immediate access. The session will also cover DevOps automation tools that ensure rapid distributed deployment of big data security across thousands of nodes.

Speaker: Adrian Cockcroft, Cloud Architect at Netflix

Speaker: Ken Krugler, Big Data Consulting at Scale Unlimited
Slides: http://www.slideshare.net/planetcassandra/c-summit-2013-suicide-risk-prediction-using-social-media-and-cassandra-by-ken-krugler
In this presentation, Ken will describe a portion of an early-phase project that uses social media data (tweets, Facebook posts, etc.) from service personnel to predict suicide rates. There's a lot of motivation to provide better data for military psychologies, since more military wind up taking their own lives than are killed in the line of duty. By analyzing social media data that is voluntarily provided by personnel, plus a predictive analytics system, we can provide assessments that help mental health workers focus their time and energy on the most at-risk individuals. This project uses Cassandra as the scalable storage system for this social media data, which is then analyzed in a distributed environment using Hadoop. The project also uses the Solr search support from DataStax Enterprise to provide ways for users to dig into the underlying data, which is critical when understanding the assigned risk levels.

Speaker: Renato Javier and Lewis John McGibbney
Slides: http://www.slideshare.net/planetcassandra/c-summit-2013-taking-bytes-from-cassandra-clients-by-renato
Since early 2012 Gora has been proudly participating as an honorary Incubator post-grad within the ASF. This presentation provides Renato and Lewis' perspective on a phenomenon they refer to as the "big datastore client wars", which is a real life challenge they've discovered whilst attempting to integrate several big data backends (Accumulo, Cassandra, HBase, MySQL, HSQLDB, Amazon's DynamoDB, MongoDB) under one common persistence layer and, in the process, obtain optimal results over Gora operations. They emphasize their approach to addressing this problem by discussing a pluggable Cassandra client infrastructure (Hector-client, Datastax java driver, intravert-ug, etc) adapted specifically for the gora-cassandra module.

Speaker: Sylvain Lebresne, Apache Cassandra Committer and Engineer at DataStax
Slides: http://www.slideshare.net/planetcassandra/cassandra13-state-of-cql
Since its inception, the Cassandra Query Language (CQL) has grown and matured, resulting in the 3rd version of the language (CQL3) being finalized in Cassandra 1.2. Compared to the legacy Thrift API, CQL3 aims at providing an API that is higher level and more user friendly but still fully assumes the distributed nature of Cassandra and it's storage engine. This presentation will present CQL3, describing the reasoning and goals behind the language as well as the language itself. CQL's relationship with Thrift will be touched on, along with the CQL binary protocol that has been introduced in Cassandra 1.2. This presentation will wrap up by discussing the future of CQL.

Gnip ingests and must serve out hundreds of millions of social activities every day and social platforms are only growing. This makes the scalability of applications essential for Gnip. Enter Cassandra. Problem solved, right? Not exactly, Gnip's relationship with Cassandra was not all rainbows and unicorns. In this session we will walk you through why we began looking at Cassandra as a data store in the first place and the valuable lessons we with Cassandra that has made it an invaluable part of our infrastructure.

NativeX (formerly W3i) recently transitioned a large portion of their backend infrastructure from Microsoft SQL Server to Apache Cassandra. Today, its Cassandra cluster backs its mobile advertising network supporting over 10 million daily active users that produce over 10,000 transactions per second with an average database request latency of under 2 milliseconds. Come hear our story about how we were successful at getting our .NET web apps to reliably connect to Cassandra. Come learn about FluentCassandra, Snowflake, Hector, and IKVM. It's a story of struggle and perseverance, where everyone lives happily ever after.
