#MYSQL OPTIMIZER DIFFERENT RESULTS BETWEEN SERVERS INSTALL#

Step 1 - Installing and Setting Up the MySQL Serverįirst, you will install MySQL server and configure it to be used by ProxySQL as a back-end server for serving client queries.

Prerequisitesīefore you begin this guide you’ll need the following: You will then test its performance using mysqlslap with and without caching to demonstrate the effect of caching and how much time it can save when executing many similar queries. In this tutorial, you will use ProxySQL to set up transparent caching for a MySQL server on Ubuntu 16.04. All the developer needs to do is connect to the protocol-aware proxy, and the proxy will decide if the query can be served from the cache without hitting the back-end server. In transparent caching, only database administrators need to change the ProxySQL configuration to enable caching for the most common queries, and these changes can be done through the ProxySQL admin interface. To avoid this error-prone practice, ProxySQL allows you to set up transparent caching. But in many caching methods, developers must modify the code of their application, which could introduce a bug into the codebase. This can significantly increase the speed of common queries. MySQL caching occurs when the result of a query is stored so that, when that query is repeated, the result can be returned without needing to sort through the database. This tutorial will focus on ProxySQL’s caching feature, and how it can optimize queries for your MySQL database. It offers many features, such as load-balancing between multiple MySQL servers and serving as a caching layer for queries.

ProxySQL is a SQL-aware proxy server that can be positioned between your application and your database. The author selected the Free Software Foundation to receive a donation as part of the Write for DOnations program.
