Time: Thursday 09:45 - 10:30 / Location: Room 1

Unless you have implemented architectures that use NoSQL databases and frameworks that support data-intensive distributed applications, then myriads of options are probably a slight enigma.
This session will give you an insight into what to consider when you need to make a NoSQL column based database like Cassandra work together with data-intensive distributed framework like Hadoop.
• The basic product idea

- The problem: need to collect, process and store 5Tb of data daily
• The solution: A combination of Cassandra, Hadoop and some MySQL
• Best practices for modeling your data in Cassandra
• Best practices for scaling Hadoop Clusters
