[Read more]In my last post I compared data at-rest encryption features available for MySQL and MariaDB. As noted at the time, some of the features available for Percona Server for MySQL were in development, and the latest version (5.7.23) sees two of them released as ALPHA quality.
Encrypting the InnoDB system tablespace
The first of the new features is InnoDB system tablespace encryption via innodb_sys_tablespace_encrypt, which …

[Read more]In this blog post we shall discuss how you can analyze slow query logs from Amazon Aurora for MySQL, (referred to as Amazon Aurora in the remaining blog). The tools and techniques explained here apply to the other MySQL compatible services available under Amazon Aurora. However, we’ll focus specially on analyzing slow logs from Amazon Aurora version 2 (MySQL 5.7 compatible) using pt-query-digest. We believe there is a bug in Aurora where it logs really big numbers for query execution and lock times for otherwise really fast queries.
So, the main steps we need are:
Oracle MySQL Support will this year again take part in the Oracle OpenWorld conference in San Francisco. Additionally, we will present at the developer focused Code One that is held at the same time.

Manual deployments can also be tedious and repetitive. Depending on the number of nodes in the cluster, the deployment steps may be time-consuming and error-prone. Configuration management tools like Puppet, Chef and Ansible are popular in deploying infrastructure, but for stateful database clusters, you need to perform significant scripting to handle deployment of the whole database HA stack. Moreover, the chosen template/module/cookbook/role has to be meticulously tested before you can trust it as part of your infrastructure automation. Version changes require the scripts to be updated and tested again.
The good news is that ClusterControl automates deployments of the entire stack - and for free as well! We’ve deployed thousands of production clusters, and take a number of …
[Read more]Experimental Build of Percona XtraBackup 8.0 released
An experimental alpha version of Percona XtraBackup 8.0.1 is now available in the Percona experimental software repositories.
A few things to note about this release:
MySQL 5.7 and 8.0 have an issue of stopping replication on all slaves.
Everyone knows those situations where there is a task that you need to do and you want to do, but you just don’t come around to actually doing it. Well, for me, this new release was such a task.
Early in 2017, I released the first version of puppet-proxysql on GitHub. It was my first puppet-module release and I was quite proud of it. I had implemented types and providers for managing the ProxySQL resources such as mysql_user, mysql_servers, etc…
At Config Management Camp Gent (February 2017) I met Vox Pupuli, who is the group that forms the puppet-user-community. They picked up the responsibility of taking ownership of well-known modules that are left unmaintained or abandoned and/or modules that only had a single maintainer. The puppet-proxysql module was kind of the latter. Additionally, they …
