One of the great strengths of MySQL and one of the main features which sets it apart from other RDBMSs is its ability to use different storage engines for different tables. These different storage engines can control where and how the data is stored and retrieved. Every storage engine has strengths and weaknesses, which means that MySQL can be tailored to the user's need through its use of storage engines.
In this chapter, we will outline everything you need to create your own storage engine. We will then finish off the chapter with an example of a simple read-only storage engine plugin.
