+0 Vote Up -0Vote Down

Multithreaded Replication to the Rescue
+0 Vote Up -0Vote Down

Recently, I set up several new database pairs for our backend search team to use. After bringing them online, the search team began backfilling data by writing to the A-side. A bit later, I noticed that replication had started falling behind, maxing out at ~1000 inserts/second.

There isn’t too much unusual about these servers. They run Percona Server 5.6.19 to take advantage of the TokuDB storage engine option …

Free Webinar! What Should I Monitor, and How Should I Do It?
+0 Vote Up -0Vote Down

Monitoring tools offer alerts based on thresholds and time-series charts of status counters, but they do not tell us what we should monitor. On Tuesday, February 10th at 2 PM EST, Baron Schwartz will discuss the guiding principles needed to answer these questions.

The following questions will be answered:

  • What status counters from MySQL are central and core, and which are peripheral?
  • What is the meaning of MySQL status metrics?
  • Which subsystems inside MySQL are the most common causes of problems in production?
  • What is the unit of work-getting-done in MySQL, and how can you measure it?

MySQL-next = Drizzle 5 years ago?

With JSON functionality, alternate protocols (HTTP, memcache), a move towards saner defaults and crash safety, pluggable logging etc it really looks like MySQL is following what we did in Drizzle years ago, which is great!

+0 Vote Up -0Vote Down

I recently updated the High Performance MySQL website to modernize it. I am impressed at how easy it is these days to get a great little brochure site hosted. It used to be a lot more work. I used a variety of tools and services to do this and decided to share this for people who are interested. Hopefully you’ll add comments and point me towards more tools and tips to make these things even easier for me in the future!

Employee +1 Vote Up -0Vote Down

So how do you use MySQL Fabric to set up a Highly Available Server Farm? The last two postings in this series were on installing Fabric on a master and then setting up slaves. Now it is time to get get the Fabric Farm started.

The Fabric controller is node number 1 and the slaves are 10, 20, and 30 at IP 10.10.13.1, 10, 20, and 30 respectively. I am keeping with the last octet of the IP addresses for clarity. I am trying to recreate the Fabric Farm from this image.

On the 10, 20, and 30 systems we need to add the following to the mysld section of the my.cnf

The 2015 MySQL Community Awards event will take place, as usual, in Santa Clara, during the Percona Live MySQL Conference & Expo, April 2015.

The entire process of discussing, voting and awarding is controlled by an independent group of community members, typically based of past winners or their representatives, as well as known contributors.

It is a self-appointed, self-declared, self-making-up-the-rules-as-it-goes committee. It is also very aware of the importance of the …
