Sharding PHP with MySQL Fabric
Employee +0 Vote Up -0Vote Down

PHP users who attended any of my recent PHP&MySQL related talks or read Ulf's blog will know our mysqlnd_ms plugin. This plugin hooks into PHP's mysqlnd library and provides transparent support for replication and load-balancing features. Without changing your application you get transparent load-balancing and read-writ splitting so all your reading queries will be sent to a slave while the writes go to a master server. The exact strategies for that can be defined in mysqlnd_ms's configuration so quite often no, or only few application changes are needed. But we have one limitation: The MySQL servers have to be configured in each configuration on all your PHP servers, this can be annoying when you're changing your environment like adding a new slave or promoting a machine to master in case

MySQL Query Analyzer and PHP
Employee +2 Vote Up -0Vote Down

Today we've released a few things for PHP and MySQL users: One is the first (and probably only) beta of the mysqlnd_ms plugin for MySQL Replication and Load Balancing support and the first GA version of a PHP plugin for the Query Analyzer of the MySQL Enterprise Monitor.

Ulf blogged a lot about mysqlnd_ms, so I don't have to repeat him here. what I want to talk about is the other one. So what is that about?

When running a PHP-based application with MySQL it is often quite interesting to see what actually happens on the database sever. Besides monitoring of the system load etc. it is often interesting to see what queries are actually executed and which of them are expensive. A part of MySQL Enterprise Monitor is the MySQL Query Analyzer

mysqlnd plugins and json
Employee +3 Vote Up -0Vote Down

Some time ago I was already writing about the power included with mysqlnd plugins and how they can they can be used transparently to help you with your requirements without changing your code. But well, as mysqlnd plugins in fact are regular PHP extensions they can export functions to the PHP userland and providing complete new functionality.

In my spare time I'm currently writing a shiny Web 2.0 application where I'm heavily using AJAX-like things, so what I do quite often in this application is, basically this: Check some pre-conditions (permissions etc.) then select some data from the database, do a fetch_all to get the complete result set as an array and run it through json_encode; or to have it in code:

<?php
$m = new MySQLi(/*...*/);

mysqlnd plugins for PHP in practice
Employee +1 Vote Up -0Vote Down

If you follow my blog or twitter stream you might know I've recently been at Barcelona to attend the PHP Barcelona conference. Conferences are great for exchanging ideas one of the ideas I discussed with Combell's Thijs Feryn: They are a hosting company providing managed MySQL instances to their customers, as such they run multiple MySQL servers and each server serves a few of their customers. Now they have to provide every customer with database credentials, including a host name to connect to. The issue there is that a fixed hostname takes flexibility out of the setup. Say you have db1.example.com and db2.example.com over time you figure out that there are two high load customers

Slides from IPC and PHP Barcelona
Employee +2 Vote Up -0Vote Down
Recently I gave a few public presentations and started to convert the slides for making them available online. Here's the first bunch with slides from two conferences which were held in October, the International PHP Conference in Germany and PHP Barcelona in Spain. As always: The spoken word is missing on the slides ...
