Intro To Apache Usergrid, The BaaS Build On Cassandra - David Johnson, Apigee Corp
Whether you are building a mobile app or a web app, Apache Usergrid (incubating) can provide you with a complete backend that supports authentication, persistence and social features like activities and followers all via a comprehensive REST API — and backed by Cassandra, giving you linear scalability. All that, and Usergrid is open source too.

This session will explain how you can use Usergrid to provide a back-end for your application. We’ll start with an overview of Usergrid features, then explore in depth how to authenticate users, store data and query data with the REST API provided by a Usergrid server. We’ll develop a simple HTML5 app and package it as a native mobile app via Apache Cordova. We'll also cover how to run Usergrid locally for development and testing.

Time Series Data With Apache Cassandra - Eric Evans, OpenNMS Group
Whether it's statistics, astronomy, finance, or network management, time series data plays a critical role in analytics and forecasting. Yet, while many tools exist, few are able to scale past memory limits; For those challenged by large volumes of data, there is much room for improvement.

Apache Cassandra is a fully distributed second-generation database. Cassandra stores data in key-sorted order making it ideal for time series, and its high throughput and linear scalability make it well suited to very large data sets.

This talk will cover some of the requirements and challenges of large scale time series storage and analysis. Cassandra data and query modeling for this use-case will be discussed, and Newts, an open source Cassandra-based time series store under development at The OpenNMS Group will be introduced.
