Awesome MySQL 5.7 improvements
+0 Vote Up -0Vote Down

Recently, I’ve had reason to poke at MySQL performance on some pretty cool hardware. Comparing MySQL 5.6 to MySQL 5.7 is a pretty interesting thing to do when you have many CPU cores.

The improvements to creating read views in InnoDB is absolutely huge for small statements with large concurrency – MySQL 5.7 completely removes this as a bottleneck – as much as doubling maximum SQL queries per second, which is a pretty impressive improvement.

I haven’t poked at the similar improvements in Percona Server on this hardware setup – so I can only really guess as to the performance characteristics of it… If comparing to older MySQL …

May 23, 2014 By Severalnines

If you need to deploy a database cluster behind your corporate firewall, on servers with no internet access, then this blog is for you. Most of the installation tutorials out there require servers to have an internet connection, and that would not work very well with companies under strict policies and compliance guidelines.

+0 Vote Up -0Vote Down

April 24, 2014 By Severalnines

ClusterControl 1.2.6 introduces integration with Active Directory and LDAP authentication. This allows users to log into ClusterControl by using their corporate credentials instead of a separate password.

This blog shows you how to configure LDAP authentication in ClusterControl, and allow users to use their …

Reflections on return to MySQL Community and Ecosystem
+1 Vote Up -0Vote Down

After a four year hiatus, my participation in last week’s Percona Live MySQL Users conference marked my official return to the MySQL Community and Ecosystem.

Yahoo’s Performance Analyzer

Yahoo is developing a MySQL performance analyzer that should be released as open source later this year. From the demo, it looks like it pulls in most of the MySQL metrics, shows you a processlist and then lets you drill into a processlist with explain. Will have to keep my eye out for this.
