Scaling Big Data with Hadoop and Solr

By: Hrishikesh Vijay Karambelkar

Overview of this book

<p>As data grows exponentially day-by-day, extracting information becomes a tedious activity in itself. Technologies like Hadoop are trying to address some of the concerns, while Solr provides high-speed faceted search. Bringing these two technologies together is helping organizations resolve the problem of information extraction from Big Data by providing excellent distributed faceted search capabilities.</p> <p>Scaling Big Data with Hadoop and Solr is a step-by-step guide that helps you build high performance enterprise search engines while scaling data. Starting with the basics of Apache Hadoop and Solr, this book then dives into advanced topics of optimizing search with some interesting real-world use cases and sample Java code.</p> <p>Scaling Big Data with Hadoop and Solr starts by teaching you the basics of Big Data technologies including Hadoop and its ecosystem and Apache Solr. It explains the different approaches of scaling Big Data with Hadoop and Solr, with discussion regarding the applicability, benefits, and drawbacks of each approach. It then walks readers through how sharding and indexing can be performed on Big Data followed by the performance optimization of Big Data search. Finally, it covers some real-world use cases for Big Data scaling.</p> <p>With this book, you will learn everything you need to know to build a distributed enterprise search platform as well as how to optimize this search to a greater extent resulting in maximum utilization of available resources.</p>

The problem


Apache Solr is an open source, extendible, and enterprise search having effective community development focused on enhancing it every day. Searching has evolved over time, from basic web-crawling documents search to more sophisticated structured/unstructured content search that provides a lot of user interactions. As the data grows, there is a paradigm shift and more focus is towards the effective use of MapReduce or similar distributed technology for handling such a high volume of data. At the same time, the cost of enterprise storage also needs to be controlled.

By design, Apache Lucene and Solr are designed to support large scale implementation. Apache Solr based distributed environment is useful when:

  • Speeding up the search: If Apache Solr is taking longer time for creation of indexes from raw data or for searching on a keyword across the index store, it is possibly the best candidate to run in a distributed environment.

  • Index generation time: Incremental generation of indexes...
