Databases are everywhere, but did you ever wonder what goes on inside the box? In this talk we’ll dive into the internals of Neo4j - a popular graph database - and see how its designers deal with distributed systems challenges now and in the future. Borrowing heavily from the academic literature, we'll see why computers are far too easy to program and why oppositely distributed systems are far too hard. We'll follow that with some approaches to making distributed systems safer and contrast that with conflicting approaches that make systems more scalable! If that doesn't sound nightmarish enough, we'll finish up by showing how we can build systems that are safe and scalable by borrowing and gluing together a bunch of ideas from folks who are smarter than me. Come experience the last 10 years of my harrowing day job in less than an hour. You might even enjoy it, or at least empathise!

In this talk we’ll explore powerful analytic techniques for graph data. Firstly we’ll discover some of the innate properties of (social) graphs from fields like anthropology and sociology. By understanding the forces and tensions within the graph structure and applying some graph theory, we’ll be able to predict how the graph will evolve over time. To test just how powerful and accurate graph theory is, we’ll also be able to (retrospectively) predict World War 1 based on a social graph and a few simple mechanical rules.Then we’ll see how graph matching can be used to extract online business intelligence (for powerful retail recommendations). In turn we’ll apply these powerful techniques to modelling domains in Neo4j (a graph database) and show how Neo4j can be used to drive business intelligence. Don’t worry, there won’t be much maths.

Running an open source B2B business is a tough gig. Not only can anyone see where the bodies are buried but there’s a constant tension between various stakeholders: OSS enthusiasts, customers, and employees with respect to the software. At Neo4j we see architecture as one possible organising principle around which all stakeholders can gather. In this talk I’ll describe Neo4j and its architecture and discuss how we communicate and evolve the product to bring along all stakeholders. I’ll also talk about some of the hardships that architecture alone cannot solve and look to the audience to help us out with some of our thornier corner-cases.

This workshop is aimed at the people new to Neo4j but curious about what graphs can do for them and their business. In this highly practical session we'll explore what a graph database is and how data modelling works for graphs. We will also touch on a little graph theory and DBMS architecture for depth.

The workshop is split into multiple sessions, each with substantial practical elements - so bring your laptop!

In this talk we’ll explore the new Causal clustering architecture for Neo4j. We’ll see how Neo4j uses the Raft protocol for a robust underlay for intensive write operations, and how the asynchronous new scale-out mechanism provides enormous capacity for very demanding graph workloads.

We’ll discuss the cluster architecture’s new causal consistency model. Causal consistency is a big leap forward compared to the commonplace eventual consistency which makes it convenient to write applications that use the full capacity of the cluster. In particular we’ll show how despite the mixture of concensus protocols and asynchronous replication, that Neo4j allows users to read their own writes straightforwardly and discuss why this is such a difficult achievement in distributed systems.

For the application developer, we’ll show how Neo4j’s Causal Clustering optimised drivers makes it easy to write applications that scale smoothly from a single server to a large, distributed cluster: a practical motivation for the distributed systems enthusiast.
