1. Developing Analytics in Applications

    Adding analytic visualizations to a software application provides critical visibility to enhance business performance. There are multiple options for achieving analytics, each with distinct functional, cost, and operational characteristics. To choose the best approach, development teams need to understand both upfront and downstream operational requirements. This presentation overviews options for embedding analytics while pointing out key considerations for selecting the best approach.

  2. Our goal is to design a highly scalable, fault tolerant, easily manageable and robust, system, to provided extremely effective and efficient search capabilities and capable of handling very high transaction volume, using an open source solution. Why we opted to use SOLR, a brief overview of our old multicore architecture, its performance, scalability, availability and pain points.

    Dive into our new Multi-Tier Hybrid SOLR Cloud architecture, its performance, availability, scalability and cost benefits and lessons learnt in use of SOLR to provide mailbox search capability for AOL mail users.

    Rishi Easwaran is a Principle software engineer working with the AOL mail team since 2008 and the tech lead for our existing mail search infrastructure and Re-architecture efforts to implement a Multi-tiered high availability, large scale Hybrid-SOLR Cloud solution. Over the years the entire team focused on performance, availability and scalability of SOLR and in our efforts to accomplish this we dove into the source code and have a close working knowledge and experience with SOLR.

    Lumify is a relatively new open source platform for big data analysis and visualization, designed to help organizations derive actionable insights from the large volumes of diverse data flowing through their enterprise. Utilizing popular big data tools like Hadoop, Accumulo, and Storm, it ingests and integrates many kinds of data, from unstructured text documents and structured datasets, to images and video. Several open source analytic tools (including Tika, OpenNLP, CLAVIN, OpenCV, and ElasticSearch) are used to enrich the data, increase its discoverability, and automatically uncover hidden connections. All information is stored in a secure graph database implemented on top of Accumulo to support cell-level security of all data and metadata elements. A modern, browser-based user interface enables analysts to explore and manipulate their data, discovering subtle relationships and drawing critical new insights. In addition to full-text search, geospatial mapping, and multimedia processing, Lumify features a powerful graph visualization supporting sophisticated link analysis and complex knowledge representation.

    This talk will blend a high-level use case demo with a more technical presentation of Lumify's underpinnings, focusing on its use of Accumulo to implement fine-grained access control of the graph data.

    Building real-time notification systems is often limited to basic filtering and pattern matching against incoming records. Allowing users to query incoming documents using Solr's full range of capabilities is much more powerful. In our environment we needed a way to allow for tens of thousands of such query subscriptions, meaning we needed to find a way to distribute the query processing in the cloud. By creating in-memory Lucene indices from our Solr configuration, we were able to parallelize our queries across our cluster. To achieve this distribution, we wrapped the processing in a Storm topology to provide a flexible way to scale and manage our infrastructure. This presentation will describe our experiences creating this distributed, real-time inverted search notification framework.

    Running Hadoop isn't easy. Many clusters suffer from configuration problems that can negatively impact performance. With vast and sometimes confusing configuration options, it can can be scary to make changes to Hadoop when performance isn't as expected. Learn how to improve Hadoop performance and eliminate common problem areas using a handful of simple and safe Linux configuration changes.
