Many developers use master-slave replication to solve a number of different problems, including problems with performance, supporting the backup of different databases, and as a part of a larger solution to alleviate system failures. Traditionally, master-slave replication is done with real servers, but it can also be done with cloud database servers. This guest post from Jelastic (originally published here) describes how to set up MariaDB master-slave replication using their Jelastic PaaS (Platform as a Service).

MySQL Workbench: Data Modeling & Development
Michael McLaughlin
Oracle Press
ISBN 978-0-07-178188-5

MySQL Workbench is one of those tools that quickly becomes invaluable. It is a SQL query tool, a data modeler, and an admin tool all in one. As such a complicated tool, there is a bit of a learning curve before one can move beyond the basic functionality. Now there is a book that not only is a guided tour of MySQL Workbench but it contains little snippets full of DBA and system admin tricks that make this a must have for anyone using Workbench.

The book is divided into six sections that starts with configuration. This part of the book assumes now previous database or MySQL background as it gently guides you through the installation of the key components on mac OS X, Windows, and Linux. …

Got a packet bigger than ‘slave_max_allowed_packet’ bytes and binlog_format=STATEMENT|MIXED

Since version 5.1.64 MySQL introduces a new variable named slave_max_allowed_packet, which was introduced to allow large updates using row-based replication do not cause replication to fail when exceeded max_allowed_packet.

The problem is if you have you replication using binlog_format=STATEMENT or binlog_format=MIXED it ignores this option and use as limit for queries what is on max_allowed_packet variable but still reporting on slave_max_allowed_packet causing the IO_THREAD to report the wrong message.

5 years of MySQL

People often write a blog post when they reach some nice anniversary since they joined MySQL community. Well, for those old enough it usually means when they joined MySQL AB as employee. For me this was January 2008. Because I didn't remember the month correctly, I haven't blogged anything then, but decided to save it for a better opportunity - now.

TL;DR Starting this week I will be working for 10gen, selling MongoDB to the Nordics. This blog post is really long - even then it doesn't contain the most interesting stories, I'm not sure if they can ever be published. Sorry for the length, but remember you don't need to read all at once. This is my last MySQL post so save some of it for cold winter days!

Galera/Percona XtraDB Cluster (PXC) for MySQL is a hot thing right now and some users jump right in without enough testing. Consequently, they’re more likely to either suffer failure or issues that prevent them from moving forward. If you are thinking of migrating your workload to Percona XtraDB Cluster, make sure to go through these basics.

log_slave_updates is REQUIRED

You need to have log_slave_updates enabled on the cluster node acting as async slave for replicated events from the async master to be applied to the other nodes, that is if you have more than one PXC node. This is because before Galera can create writesets for the replicated events, binlog events must be generated for the transactions first. Under …

I wasn’t at the MySQL Conference this year but it was very nice to follow this event from Paris.
Of course I didn’t feel the general atmosphere by visiting booths or met fabulous people.
But it was a great opportunity to offer you a live post about the conference with an external point of view.

Twitter, RSS feeds (yes Google, I still use RSS), Planet MySQL and infiltrators were my best friends during this crazy week.

MySQL Connector/Net 6.7.2, a new version of the all-managed .NET driver for MySQL has been released.  This is the first beta release intended to introduce users to the new features in the release.  This release is feature complete, it should be stable enough for users to understand the new features and how we expect them to work.  As is the case with all non-GA releases, it should not be used in any production environment.  It is appropriate for use with MySQL server versions 5.0-5.7.
