Introducing Log4j 2.0
The Apache Log4j framework is one of the most wide-spread Java logging frameworks with very few competitors. Although many logging frameworks exist for Java, many of these are simply facades for other logging frameworks. In this presentation, Matt Sicker will introduce the next generation of Log4j, including an overview of the new features, plugins, and APIs available in Log4j, along with the general state of logging frameworks in the Java ecosystem.

Log4j 2 in Web Applications: A Deeper Look at Effective Java EE Logging
The newly-released Log4j 2 includes much greater support than previous versions for Java EE web applications and proper initialization and deinitialization of the framework with the application lifecycle. The Servlet and JSP specifications have changed significantly in the 12 years since Log4j 1.2 first released. Some of those changes make logging easier, and some of them make it harder. In this presentation you will learn about properly configuring Log4j in a web application, what to do when the container is using Log4j, how to log within your JSPs using the Log4j tag library, and what to do when handling requests asynchronously.

Apache Commons Pool and DBCP
Commons Pool provides a generic object pooling API and several object pool implementations. Commons DBCP uses Commons Pool to create a JDBC database connection pool. Together, these components provide the default database connection pool that ships with Apache Tomcat. Both of these components have recently been released in new major versions, shipping with Tomcat 8. The core pooling implementation in Commons Pool has been completely rewritten to improve performance, scalability and manageability. DBCP has been adapted to leverage the new pool version while adding many new features as well. This session will provide an overview of the new features along with practical recommendations on how to configure and use Commons Pool and / or DBCP to handle different kinds of workloads and resource constraints.

Your Graph is Showing: The Trend toward Graph Databases
Developers have turned to NoSQL databases, such as MongoDB and Cassandra, to build social networks and online communities because of their relative speed and simplicity.  However, when creating connections, understanding trends and seeing commonalities within data, developers at places like Facebook and Twitter have increasingly turned to graph databases.

In this discussion, we'll start with a quick overview of the database landscape and how graph databases fit within it.  Next, we'll dive into neo4j, a popular graph database, and demonstrate how to solve complex, connected data problems with an in-depth look at examples demonstrating the power, speed and simplicity of using graph databases.  We'll close with a look at some caveats as well as glimpse into the future of graph databases.

Turning NoSQL data into Graphs - Playing with Apache Giraph and Apache Gora
Apache Gora provides an in-memory data model and persistence for big data. The journey for Gora has also featured an uptake in collaboration with high-profile projects and exciting participation in Google's Google Summer of Code (GSoC) program.
One of this year's exciting GSoC project was the integration of Apache Gora with Apache Giraph. Apache Giraph is an iterative graph processing system built for high scalability. For example, it is currently used at Facebook to analyze the social graph formed by users and their connections. This presentation combines lessons learned while integrating two awesome Apache Projects (Apache Giraph and Apache Gora), and showing NoSQL users the ability of performing graph analysis just the way Facebook, LinkedIn, Twitter, and other big internet companies do with their huge graphs of data, by just writing some Input/Output classes in Giraph for Gora.

Deploying Apache Gora as a Query Broker
Lewis John McGibbney - The Apache Gora open source framework provides an in-memory data model and persistence for big data. Gora supports persisting to column stores, key value stores, document stores and RDBMSs, and analyzing the data with extensive Apache Hadoop MapReduce support. In this presentation Lewis will cover his work on deploying Gora as a query broker in order to address information retireval problems presented within the field of federated web search. The presentation will provide an in-depth account of the problem scenario, the proposed solution including code examples and a running example of how Gora can be deployed to address such as dataset resource selection and results merging.
