Preface

Preface

 

 

    I've implemented ProxySQL on PXC yesterday but got some errors when configured query rules.I'm gonna do it again in my master-slave environment again.Let's see the procedure.

    As we all know,it's a common sense that separate reading and writing operations can immensely increse the performance of MySQL database.Especially the query operations by executing select statement relevant with large tables.Therefore,we usually choose a proxy tool to deal with it.There're a lot of tools can be used nowadays such as mycat(by Apache),dble(based on mycat by Action),atlas,dbproxy(based on atlas of Qihoo360 by MeituanDianping),cetus(by NetEase) and so forth.I'm not going to compare who's the better tool to use.I'm just prefer to having a test on another popular tool which is called "ProxySQL".

 

 

Procedure

Introduce

 

 

Start ProxySQL.

    ProxySQL is a low-weight proxy tool based on a SQLite database.It provids hight performance espcially in high concurrent environment what we can see below(compared with the MaxScale).
