In this video, Manish Sood from Reltio presents: Cassandra: A Foundation for Real-time Big Data Applications at Reltio.

Reltio provides the world’s largest enterprise customers with real-time Big Data Applications that help business users understand markets, drive revenue and reduce risk through actionable, real-time and predictive insights integrated into applications and dashboards. These applications require the ability to not only handle data scale, latency, and high availability but also deliver capabilities that address reconciliation of data from multiple sources, handle multiple dimensions (various entities, relationships and interaction data) of varying complexity, with the ability to track audit and bi-temporal data. To solve this challenge, Reltio leverages Cassandra as the enabling data store for multi-tenancy, complex attribute structures, graph storage, real-time search and analytics. These capabilities are delivered as a Service to customers across verticals to address scenarios such as Extended Client views, Client experience & engagement, and Risk & Compliance.

In this video, Adrian Cockcroft from Netflix presents: Cassandra Performance and Scalability on AWS.

Netflix published a Cassandra scalability benchmark in 2011 that showed linear scalability as the number of nodes in the cluster was increased from 48 to 288 and over a million triple replicated writes per second. This talk will summarize a range of new benchmarks that take advantage of more powerful EC2 instances and improvements in Cassandra itself.

Key findings so far in the 2012 Big Data Index indicate:

• Over 15,000 Big Data connectors were downloaded in 2011;
• Demand for MongoDB, the document-oriented NoSQL database, saw the biggest spike with over 200 percent growth in 2011;
• Hadoop Hive, the SQL interface to Hadoop MapReduce, represented 60 percent of all Hadoop-based connectors;
• Hadoop HBase, the distributed Hadoop environment, was the second most popular Hadoop-based connector;
• Cassandra, the high availability NoSQL database, was among the top four most downloaded Big Data sources in 2011; and
• Over 27 percent of Big Data connector downloads were for Riak, Infinispan, Neo4J, Redis, CouchDB, VoltDB or others.
