Using Percona Cloud Tools to solve real-world MySQL problems
+0 Vote Up -0Vote Down

For months when speaking with customers I have been positioning Percona Cloud Tools (PCT) as a valuable tool for the DBA/Developer/SysAdmin but only recently have I truly been able to harness the data and make a technical recommendation to a customer that I feel would have been very difficult to accomplish otherwise.

Let me provide some background: I was tasked with performing a Performance Audit for one of …

MaxScale Firewall Filter

MaxScale’s filter system is very flexible and enables a new way of interacting with queries. The upcoming firewall filter shows just one of the many ways that you can control and manage the flow of queries through MaxScale.

The firewall filter is meant to offer finer and more varied control over queries and their execution. The main idea of the filter is to work as a base to build and improve upon and to show just how that can be done with MaxScale.

Distributed and Diverse: The New Reality of Modern Data Persistence
+0 Vote Up -0Vote Down

We create applications in an age of simple, powerful, flexible databases that do magic for us. There’s a large variety of modern databases that supply just what’s needed for lots of use cases, so we can pick the right tool for the job. We’ve never had it better, right? So why is “it’s the database again” still a sufficient explanation for a lot of outages and performance problems?

Mo’ Data, Mo’ Problems
+0 Vote Up -0Vote Down

Welcome to blog #2 in a series about the benefits of the Fractal Tree. In this post, I’ll be explaining Big Data, why it poses such a problem and how Tokutek can help. Given the fact that I am a lifelong fan of both Hip-hop and Big Data, the title was a no-brainer and, given the artist, a bit of a pun.

 I am as tired as you of hearing the term “Big Data.” It’s so overused, that it ceases to have specific meaning anymore. You see, data hardly ever starts as “big” or a “problem.” Rather, it starts small and easily manageable, but gradually grows to some unimaginable size and becomes a beast in need of slaying, like …

Tracking MySQL query history in long running transactions
+0 Vote Up -0Vote Down

Long running transactions can be problematic for OLTP workloads, particularly where we would expect most to be completed in less than a second. In some cases a transaction staying open just a few seconds can cause behaviour that is entirely unexpected, with the developers at a loss as to why a transaction remained open. There are a number of ways to find long running transactions, luckily versions of MySQL from 5.6 onwards provide some very insightful instrumentation.
