Announcing MySQL Monitoring Plugins from Percona

We’ve released a new set of monitoring plugins for MySQL servers and related software. With these plugins, you can set up world-class graphing and monitoring for your MySQL servers, using your own on-premises Cacti and Nagios software. The Cacti plugins are derived from an existing set of templates we’ve been using for several years, but […]

White Paper: Flashcache and MySQL on Virident drive

Our latest MySQL white paper is Improving Percona Server performance with Flashcache on the Virident tachIOn Drive. (Virident funded the research, but as always, we wrote the report ourselves.) The conclusion is that Flashcache can be good for read-heavy workloads, but more research is needed to understand its performance characteristics on write-heavy workloads. We explain […]

How Percona strives to remain neutral and independent

Many of the prominent companies in the MySQL ecosystem are Percona customers, including hardware manufacturers, software developers, hosted service providers, and appliance developers. We perform paid and unpaid research on their products, and we publish blog posts related to their products or services. Independence and objectivity are core Percona values. How do we balance the […]

Percona Server Scales Vertically with Virident tachIOn Drives

We’ve published a new white paper that explains how to stop sharding and start scaling vertically with PCI-E flash drives, specifically the Virident tachIOn drive, which offers consistent, low-latency IO performance. I’ve been beating this drum for a while, so it’s a great feeling to have an explicitly recommended reference architecture: buy flash storage first, […]

White Paper: Preventing MySQL Emergencies

About a year ago, I started a study of emergency incidents that our customers filed with us. What I found was really surprising, and defied conventional wisdom. I learned a lot about preventing emergencies. I just published the outcome as a white paper, including checklists that you can use and modify for your own servers. […]

Goal-Driven Performance Optimization white-paper available

If you were at last month’s MySQL conference, you might have seen a small flyer we were distributing, titled “A brief introduction to Goal-Driven Performance Optimization.” This is a super-compressed technical introduction to one of the methods we use to solve problems as quickly and efficiently as possible. We’ve just posted this on a new […]

MySQL Query Cache WhiteSpace and comments

Commenting on my previous post on MySQL Query Cache Gerry pokes me as I’m all wrong and both comments and whitespace are fixed in MySQL 5.0. This was not what I remember seeing in production so I decided to do some tests on the matter:

Sysbench Benchmarking of Tesora’s Database Virtualization Engine

Tesora, previously called Parelastic, asked Percona to do a sysbench benchmark evaluation of its Database Virtualization Engine on specific architectures on Amazon EC2. The focus of Tesora is to provide a scalable Database As A Service platform for OpenStack. The Database Virtualization Engine (DVE) plays a part in this as it aims at allowing databases […]

Getting to know TokuDB for MySQL

During last April’s Percona Live MySQL Conference and Expo, TokuDB celebrated it’s first full-year as an open source storage engine. I still remember reading the official announcement and the expectations it created one year ago. The premises were very interesting as it had the potential of helping MySQL manage “big data” in a way InnoDB just […]

ScaleArc: Benchmarking with sysbench

ScaleArc recently hired Percona to perform various tests on its database traffic management product. This post is the outcome of the benchmarks carried out by Uday Sawant (ScaleArc) and myself. You can also download the report directly as a PDF here. The goal of these benchmarks is to identify the potential overhead of the ScaleArc […]
