Extend MySQL Master HA (MHA) capabilities with MHA Helper
+0 Vote Up -0Vote Down

I have used many tools starting with MMM to be able to manage MySQL replication clusters. Some of the tools require additional tools and complex HA solutions such as Pacemaker and Corosync, or Zookeeper. While other tools do not do the failover well which leaves the slaves in an inconsistent state, MMM would be an example. And I must say that of all the tools I love MySQL Master HA (MHA) the most. MHA is a great tool to manage MySQL replication clusters for the purpose of HA. The most important thing about MHA is that it tries to take...

Data is the most important asset any organization has especially those who belongs to web, mobile, social, enterprise and cloud applications.

Availability refers to the ability to cope with, and if necessary recover from, failures on the host, including failures of MySQL, the operating system, or the hardware and maintenance activity that may otherwise cause downtime.

Because each application has different operational and availability requirements, MySQL offers a range of certified and supported solutions, delivering the appropriate levels of High Availability (HA).

+0 Vote Up -0Vote Down

So this year the Percona Live conference has a new name — it is the “Data Performance Conference” (presumably for a much broader appeal and the fact that Percona is now in the MongoDB world as well). And the next new thing to note? You have to go through a process of “community voting”, i.e. the speaker has to promote their talks before via their own channels to see how many votes they can get (we tried this before at the MySQL & Friends Devroom at FOSDEM; in this case, please remember you also need to create a new …

Thoughts on MaxScale automated failover (and Orchestrator)
+1 Vote Up -0Vote Down

Having attended a talk (as part of the MariaDB Developer Meeting in Amsterdam) about recent developments of MaxScale in executing automated failovers, here are some (late) observations of mine.

I will begin by noting that the project is stated to be pre-production, and so of course none of the below are complaints, but rather food for thought, points for action and otherwise recommendations.

Some functionality of the MaxScale failover is also implemented …
