As Instagram has scaled to over 200 million users, so has our use of Cassandra. We've built new features and rebuilt old on Cassandra, and it's become an extremely mission-critical foundation of our production infrastructure. Rick will deliver a refresh of our use cases and go deep on the technical challenges we faced during our expansion.

This is going to talk a little bit about how to identify situations that a bot could help you, possible ways to build them, the challenges and the some things that may go wrong.

Since the launch of the PlayStation 4, many of the Sony PlayStation Network features have been delivered using Cassandra. We will be talking about our experience as we launched one of the most popular gaming consoles in the world on well over 300 nodes. Dustin and Alex cover why they picked Cassandra, what features for PS4 are powered by Cassandra and how they design, deploy, monitor, and test clusters. 

Online analytical processing (OLAP) enables real-time processing of large multidimensional databases where the potential query is not known a priority. A more light-weight approach is preferred where queries are known and where the data is not hierarchical or not structured in relational set. The advantage of NOSQL database, such as Cassandra in this light-weight model is that it can be used for caching and pre-aggregation of data sets, against known query constructs.

This talk will be a step by step walkthrough of a developer troubleshooting a real performance issue we had at MyDrive, from the very first steps diagnosing the symptoms, through looking at metric charts down to CQL queries, the Ruby CQL driver, and Ruby code profiling.

In this talk Josep draws on his experience of building a data platform based on Cassandra and Spark to service the UK's foremost player in the connected homes market.

ZFS is an advanced file, raid, and volume management system originally developed by Sun Microsystems, 'The Last Word in File Systems' has been unavailable on Linux until recently. AddThis uses ZFS to more effectively scale up dedicated hardware, getting twice the performance at half the cost.
