Capturing MySQL Data with tcpdump
+0 Vote Up -0Vote Down

Percona Toolkit has a great tool, pt-query-digest, that can use tcpdump data. Capturing raw tcp data can be taxing on a server, however, when you see the following message:

64000 packets received by filter
12000 packets dropped by kernel

When there is a significant amount of user cpu% being used, the kernel will drop packets you are trying to capture, leading to a partial picture and missing data. I’ve found that if you write it using the native tcpdump format, it’s more …

An update on the MariaDB Audit Plugin and a new version of it
+0 Vote Up -0Vote Down

I’m happy to announce that a new version of the MariaDB Audit Plugin is available. Version 1.1.5 can be downloaded here. As you can see the Audit Plugin is available from SkySQL, who has developed the plugin.

However, now with the Audit Plugin being GA for a couple of months since 7th of November last year and customers using it in production, SkySQL has decided to contribute the Audit Plugin to the MariaDB project and I’m happy to tell you that starting from MariaDB versions 5.5.37 and 10.0.9 the Audit Plugin will be included by default.

Webinar: Migrating to MySQL, MariaDB Galera and/or Percona XtraDB Cluster

Galera is slowly but surely establishing itself as a credible replacement for traditional MySQL master-slave architectures. 

The benefits are clear - a true multi-master InnoDB setup with built-in fail-over, potentially across data centers. 

But how do you migrate? Does the schema or application change? What are the limitations? Can migration be done online, without service interruption? What are the potential risks, and how to address those?

On the road again - FOSSAsia

It has been a few busy months until now. I have moved from Italy to Thailand, and the move has been my first priority, keeping me from attending FOSDEM and interacting with social media. Now I start catching my breath, and looking around for new events to attend. But before I get into this, let’s make a few things clear:

  • I am still working for Continuent. Actually, it’s because of my company flexibility that I could move to a different country (a different continent, 6 time zones away) without much trouble. …

Introducing Trite: A tool for automating import of InnoDB tablespaces
+0 Vote Up -0Vote Down


Mysqldump is a fantastic tool for backing up and restoring small and medium sized MySQL tables and databases quickly. However, when databases surge into the multi-terabyte range restoring from logical backups is inefficient. It can take a significant amount of time to insert a hundred million plus rows to a single table, even with very fast I/O. Programs like MySQL Enterprise Backup and Percona XtraBackup allow non-blocking binary copies of your InnoDB tables to be taken while it is online and processing requests. …
