solr-vs-elasticsearch

In this tutorial we will understand the difference between Apche Solr and Elastic search, Before going to actual post lets understand what is Apache Solr and what is Elastic search

Apache Solr Introduction:
Solr is an open source enterprise search server based on Lucene. Developing a high performance, feature rich application that uses Lucene directly is difficult and it’s limited to Java applications. Solr solves this by exposing the wealth of power in Lucene via configuration files and HTTP parameters, while adding some features of its own. Configuration files, most notably for the index’s schema, which defines the fields and configuration of their text analysis.

Elastic Search Introduction: ElasticSearch is a distributed, RESTful, free/open source search server based on Apache Lucene. It is developed by Shay Banon[1] and is released under the terms of the Apache License. ElasticSearch is developed in Java.

Hbase-A Soft Introduction & Quickstart

After understanding whats is Hadoop, and after deploying hadoop , lets’ start understanding HBase. This tutorial explains basics of HBase, and its features. Here I tried to explain functionality HBase provides and a quick start about HBase, a Basic tutorial for beginners. You will get to know where to use HBase, in which situation HBase can be useful.


Apache HBase
Source: Apache
Understanding What is HBase
HBase is an open source, distributed, versioned, column-oriented, No-SQL / Non-relational database management system that runs on the top of Hadoop. It adds transactional capability to hadoop, allowing users to update data records. Hadoop is designed for batch processing of large dataset, but with HBase on the top of Hadoop we can process real time dataset.
