Overview of this book

This book will take you through all the nitty-gritty parts of MariaDB, right from the creation of your database all the way to using MariaDB’s advanced features. At the very beginning, we show you the basics, that is, how to install MariaDB. Then, we walk you through the databases and tables of MariaDB, and introduce SQL in MariaDB. You will learn about all the features that have been added in MariaDB but are absent in MySQL. Moving on, you’ll learn to import and export data, views, virtual columns, and dynamic columns in MariaDB. Then, you’ll get to grips with full-text searches and queries in MariaDb. You’ll also be familiarized with the CONNECT storage engine. At the end of the book, you’ll be introduced to the community of MariaDB.

Connecting MariaDB to Sphinx

Mroonga is a new full-text search engine, and the main goal is to support the CJK languages. Until now, the most-used search engine is probably Sphinx, which has a lot of features, allows you to perform very complex queries, and performs better than the other full-text search engines.

Sphinx is a full-text search engine designed to provide better performance and relevance than the standard full-text search features shipped by default with a variety of DBMSs. Sphinx can be integrated directly with the SQL databases, or be queried directly from a script.

There are three different ways to use Sphinx. The first way is to use SphinxQL, a small SQL subset. The second is the native search API, SphinxAPI. And the last, which we will use in this chapter, is a MySQL pluggable storage engine, SphinxSE.

The key features of Sphinx are:

High indexing and searching performance
Advanced indexing and querying tools
Advanced result set post-processing
Proven scalability up to billions...
