6 September 2014 in Databases, Events, Hi-Tech, SQL

I forgot to talk about 1 meetup I’ve been regarding Neo4j. A friend (evomusic) talked to me about it and as I’m curious, I went to this meetup in July. Neo4j is a highly scalable, robust (fully ACID) native graph database. Neo4j is used in mission-critical apps by thousands of leading startups, enterprises, and governments around the world. I you don’t know what is a graph database, it’s a very good introduction and will help you to understand what it is and how it works.

Mysqlnd: replace your old php mysql client library by mysqlnd

5 May 2014 in Databases, Debian, Hi-Tech, Linux, SQL

As you may know, I’m using and loving MariaDB. A colleague recently introduced me the benefits of the php built-in MySQL/MariaDB library (shame on me, I never heard of it). Here are the informations you can find from it on the MySQL website: The mysqlnd library is highly optimized for and tightly integrated into PHP. The MySQL Client Library cannot offer the same optimizations because it is a general-purpose client library.

This covers the installation of the framework on a set of servers. The PRM framework is made of 4 components: Corosync, Pacemaker, the mysql resource agent and MySQL itself. It’s easy to setup, better if you already know how to use Pacemaker and it works like a charm. In fact it setup a master and x slaves.

1 April 2014 in Hi-Tech, Linux, SQL

And finally MariaDB 10 is out! I’m exited to finish my book about it. Here are the news: Replication MariaDB 10 sets a new standard in performance. It is many times faster than previous generations of MariaDB and especially legacy database MySQL thanks to new features including parallel replication and a further advanced group commit. Also, the replication slaves are now crash-safe. It’s also now possible to replicate data from multiple master servers giving a complete view of the distributed data across big datasets for real-time analytical purposes via the multi-source replication feature.
