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>

Understanding data-processing workflows


Based on the data, configuration, and the requirements, data can be processed at multiple levels while it is getting ready for search. Cascading and LucidWorks Big Data are few such application platforms with which a complex data processing workflow can be rapidly developed on the Hadoop framework. In Cascading, the data is processed in different phases, with each phase containing a pipe responsible for carrying data units and applying a filter. The following diagram shows how incoming data can be processed in the pipeline-based workflow:

Once a data is passed through the workflow, it can be persisted at the end with repository, and later synced with various nodes running in a distributed environment. The pipelining technique offers the following advantages:

  • Apache Solr engine has minimum work to handle while index creation

  • Incremental indexing can be supported

  • By introducing intermediate store, you can have regular data backups at required stages

  • The data...
