How to Manage All Your MySQL or MariaDB Databases
+0 Vote Up -0Vote Down

September 1, 2014 By Severalnines

According to Forrester, a DBA in a large enterprise manages between 8 and 275 databases, with the industry average being 40 databases to a DBA. Larger databases usually require extra effort around tuning, backup, recovery and upgrade. Cloud, as well as automation and management tools can help improve the number of databases managed by one DBA.  

 

With that background, we were pretty excited to introduce support for management of single-instance MySQL and MariaDB …

An Updated Description of Clustering Keys for TokuDB
+0 Vote Up -0Vote Down

Covering indexes can result in orders of magnitude performance improvements for queries. Bradley’s presentation on covering indexes describes what a covering index is, how it can effect performance, and why it works.

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. 


Our online Galera Configurator supports deployment without Internet connection for Percona XtraDB Cluster. You would need to prepare a minimum of four hosts (three DB nodes and one …

+0 Vote Up -0Vote Down

April 24, 2014 By Severalnines

This allows users to log into ClusterControl by using their corporate credentials instead of a separate password. LDAP groups can be mapped onto ClusterControl user groups to apply roles to the entire group, so it is very convenient for larger organizations who have a centralized LDAP-compliant authentication system. This blog shows you how to configure LDAP authentication in ClusterControl, and allow users to use their …
