, the community is more important than any single project code. Michael Segel: I think of Hadoop as a framework and a set of tools for distributed or parallel processing. Your distributed storage in HDFS, distributed computing models in Job tracker and task trackers, and distributed persistent object storage in HBase. Depending on the location of Hadoop, I think it depends on the specific solution. It is

Multi-core concept To put it bluntly, it is a multi-index database. It can also be understood as multiple "database tables" Let's talk about the real scenarios where multicore is used. If you say that product search and member information search are not used with multiple cores, there is no problem. As a result, there are many indexs files, in addition, the index file of the product is mixed with the index file of the member information, and backup is also a problem. If multiple cores are used,

SOLR as an enterprise-class search engine server, powerful, performance excellence, now many Web site projects in order to improve the user's good site search experience, will build SOLR to meet our professional-level search function, let's learn to configure SOLR environment together.

This morning, I suddenly wanted to write my own development process of easynet. SOLR. During this period, I encountered many problems, such as architecture problems and performance problems. I would like to share with you some of my ideas. I don't think there is any experience or something inappropriate. You are welcome to make a picture. I remember that I decided to use SOLR for the company's full-text re

Introduction Speaking of Apache Lucene, I am afraid I don't know much about Apache SOLR. Let's take a look at the description of Apache SOLR: SOLR is an enterprise-level Search Server Based on Lucene Java library, including XML/HTTP, json api, highlighting query results, Faceted search (do not know how to translate, segment-based search), caching, copy also has a

Over the past two days, I have been wondering whether to use Lucene for search applications or SOLR for search applications. Lucene only provides one queryable package. The advantage of using it for search is that I can use the corresponding functions provided by the application as needed. SOLR itself is a Lucene-based application that encapsulates Lucene, which is equivalent to development on the second la

First, this chapter mind map II. installation and deployment of SOLR 1. What are Lucene and SOLR?Lucene is a subproject of the Apache Software Foundation 4 Jakarta Project group, an open source full-Text Search engine toolkit, which is not a full-text search engine, but a full-text search engine architecture that provides a complete query engine and index engine. Part of the text analysis engine (English an

SOLR Incremental Index configuration 1. Before making an incremental index, you first need to understand several necessary attributes, as well as database-building matters, and the Dataimporter.properties data-config.xml inside the data Database Configuration Considerations 1. If only to add, and modify the business, then the database only need an additional timpstamp field can be, the default value is the current system time, Current_timestamp

Label:The integration of SOLR and MySQL databases enables the creation of full-scale indexes and incremental indexes.The rationale is simple: Register SOLR's Dataimporthandler in the SOLR project and configure the MySQL data source and the data query SQL statement. When we use the SOLR background control page or directly access an address (given later),

SOLR I am still a rookie, writing these articles is just a record of recent time to learn SOLR experience. What is SOLR?Recently, when I was learning solr, I had always seen a phrase that SOLR is an out-of-the-box search server for use in the enterprise, based on Lucene. At
