The Resilience of Apache Cassandra
Showing how Cassandra resilience can keep your data save even when a multitude of failures happen. This is a description how our team kept a 15 node cluster running (3 nodes per DC, 5 DCs) when a multiple DC fail happen and the cluster was already stretched out resource wise.

Getting Started with Apache Cassandra and DataStax
This is a crash course introduction to Cassandra. You'll step away understanding how it's possible to to utilize this distributed database to achieve high availability across multiple data centers, scale out as your needs grow, and not be woken up at 3am just because a server failed. We'll cover the basics of data modeling with CQL, and understand how that data is stored on disk. We'll wrap things up by setting up Cassandra locally, so bring your laptops.

The Role of Cassandra in a Modern Microservices Enterprise Platform
Building a Microservices platform takes time and challenges a number of traditions in our industry. Coming to grasp with the Brewer's theorem, BASE, streaming, and de-normalisation of data is a crucial step in accomplishing a successful Microservices platform.

There's a lot of theory on Microservices out there, and with your nose up to the grindstone and progress slow it can at times be difficult to relate to and to remember how important it all is. With a run through of development styles of streaming, raw event stores, event sourcing, graph databases, and drilling down to infrastructure components like Graphite, Kibana, and Zipkin, this talk will share with you the experience needed to implement Microservices, with Cassandra as a cornerstone technology, in a modern polyglot persistence enterprise platform.

With 6 years experience breaking up a monolith java+sql enterprise dinosaur into a Microservices platform today existing with over 200 thrift and http services – Mick can give a hands on account of facing these challenges.

British Gas Connected Homes: 5 Things We Wish We Had Known Before Building a Data Platform
British Gas Connected Homes (the creators of Hive Active Heating) embarked last year in the creation of a unified platform for all their different IoT projects. The company is a subsidiary of British Gas specialising in connected devices in the home and handles data ranging from smart gas and electricity meters to connected thermostats and boilers. Jim Anning and Josep Casals will go through their experience building a unified platform with Apache Cassandra, Apache Spark and related technologies. Focus will be of the main lessons learnt and the things they wish they had known beforehand.

Cassandra at Hailo
This will be a classic "use-case" story of how Cassandra fits in to Hailo, how it's enabled us to run our business, and how its made our lives easier.

I'll include a story of how our use of databases has evolved over time.

I will also give some detail on the way we've learned to tackle some common problems:
* Coping with Micro-services
* Automation
* Monitoring of Cassandra (hopefully with an introduction to a newly open-sourced monitoring tool written in-house)
* Backing it up and restoring data

Apache Cassandra Data Modeling 101
Relational systems have always been built on the premise of modeling relationships. As you will see, static schema, one-to-one, many-to-many still have a place in Cassandra. From the familiar, we’ll go into the specific differences in Cassandra and tricks to make your application fast and resilient.

Diagnosing Problems in Production
This sessions covers diagnosing and solving common problems encountered in production, using performance profiling tools. We’ll also give a crash course to basic JVM garbage collection tuning. Attendees will leave with a better understanding of what they should look for when they encounter problems with their in-production Cassandra cluster.  This talk is intended for people with a general understanding of Cassandra, but it not required to have experience running it in production.

Apache Cassandra Anti-Patterns
You wouldn't try and use a saw to hammer a nail so why do people try to use databases as queues? Or perhaps more subtly: rely on atomic updates to mutable data distributed across the world (when you say it out loud is sounds a bit ridiculous right?)

In this talk we're going to go through the most common ways to misuse Cassandra. Some are obvious and you should be using a different kind of technology, like the queue example, but others you just need to change the way you're using Cassandra.

Topics we'll cover:
* Joins (yes we'll get started with the obvious one)
* Mutable data / read then write / breaking the laws of physics
* Really wide rows (but the Internet said wide rows were good?)
* Batches!
* Multi partition queries a.k.a ReadTimeout heaven
* Secondary indexes under the covers
* Tripping over tombstones

Crazy retry policies: I am looking at you Downgrading retry policy
Misusing technology isn't isolated to the distributed database world, I used to work on a small piece of queueing software called WebSphereMQ and what do you know? A good portion of our customers used it as a database!

Building Your First Application in Apache Cassandra
You’ve heard the talks, followed the tutorials, and done the research.  You are a font of Cassandra knowledge.  Now it’s time to change the world! (Or at least build something to make your boss happy).  In this talk we’ll walk through the process of building KillrVideo, an open source video sharing website where users can upload and share videos, rate them, comment on them, and more.  By looking at a real application, we’ll talk about architectural decisions, how the application drives the data model, some pro tips when using the DataStax drivers, and some lessons learned from mistakes made along the way.  You’ll leave this session ready to start building your next application (world-changing or otherwise) with Cassandra.
