InnoDB performance optimization basics (redux)

I recently stumbled upon a post that Peter Zaitsev published back in 2007 titled “Innodb Performance Optimization Basics.” It’s a great post and reading it inspired me to examine what’s changed in the nearly six years that have followed in terms of MySQL, Percona Server – as well as in all of the other now-available […]

Considering TokuDB as an engine for timeseries data

I am working on a customer’s system where the requirement is to store a lot of timeseries data from different sensors. For performance reasons we are going to use SSD, and therefore there is a list of requirements for the architecture: Provide high insertion rate Provide a good compression rate to store more data on […]

Limited disk space? Compact backups with Percona Xtrabackup 2.1

One very interesting feature, “Compact Backup,” is introduced in Percona XtraBackup 2.1. You can run “compact backups” with the  –compact option, which is very useful for those who have limited disk space to keep the MySQL database backup. Now let’s first understand how it works. When we are using –compact option with Innobackupex, it will omit the […]

Experiences with the McAfee MySQL Audit Plugin

I recently had to do some customer work involving the McAfee MySQL Audit Plugin and would like to share my experience in this post. Auditing user activity in MySQL  has traditionally been challenging. Most data can be obtained from the slow or general log, but this involves a lot of data you don’t need too, and […]

Virident vCache vs. FlashCache: Part 2

This is the second part in a two-part series comparing Virident’s vCache to FlashCache. The first part was focused on usability and feature comparison; in this post, we’ll look at some sysbench test results. Disclosure: The research and testing conducted for this post were sponsored by Virident. First, some background information. All tests were conducted […]

Virident vCache vs. FlashCache: Part 1

(This is part one of a two part series) Over the past few weeks I have been looking at a preview release of Virident’s vCache software, which is a kernel module and set of utilities designed to provide functionality similar to that of FlashCache. In particular, Virident engaged Percona to do a usability and feature-set […]

MySQL and Percona Server in LinkBench benchmark

Around month ago Facebook has announced the Linkbench benchmark that models the social graph OLTP workload. Sources, along with a very nice description of how to setup and run this benchmark, can be found here. We decided to run this benchmark for MySQL Server 5.5.30, 5.6.11 and Percona Server 5.5.30 and check how these servers […]

Testing the Micron P320h

The Micron P320h SSD is an SLC-based PCIe solid-state storage device which claims to provide the highest read throughput of any server-grade SSD, and at Micron’s request, I recently took some time to put the card through its paces, and the numbers are indeed quite impressive. For reference, the benchmarks for this device were performed […]

Testing the Virident FlashMAX II

Approximately 11 months ago, Vadim reported some test results from the Virident FlashMax 1400M, an MLC PCIe SSD device. Since that time, Virident has released the FlashMAX II, which promises both increased capacity and increased performance over the previous model. In this post, we present some benchmark results comparing this new model to its predecessor, […]

How to use a smartphone for two-factor authentication with Percona Server for MySQL

In this post I will describe a non-trivial way to authenticate users in Percona Sever for MySQL. Percona Server comes with PAM authentication plugin, which allows you to do a lot of cool things, such as: OS authentication, LDAP authentication, even RSA Secure Server authentication (which is useful if you are required a PCI-compliance), and […]
