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>

Using SolrCloud for distributed search


SolrCloud provides fault-tolerant distributed search capabilities using Apache Solr. SolrCloud supports all types of distributed search configurations. It also has in-built load balancing capabilities that optimize effective load on all the nodes participating in SolrCloud. With the simplest configuration of all, the cloud can be set up.

Tip

A collection in Solr is a combination of one or more indexes spanning one or more cores of Apache Solr.

SolrCloud architecture

SolrCloud lets you create a cluster of Solr nodes, each of them running one or more collections. A collection holds one or more shards which are hosted on one or more (in case of replication) nodes.

Any updates to any nodes participating in SolrCloud can in turn sync of rest of the nodes. It uses Apache Zookeeper to bring in distributed coordination and configuration among multiple nodes. This in turn enables near real-time searching on SolrCloud due to active sync of indexes. Apache Zookeeper...
