Following our popular webinar on MySQL database performance tuning, we’re excited to introduce a new webinar trilogy dedicated to MySQL query tuning.

This is an in-depth look into the ins and outs of optimising MySQL queries conducted by Krzysztof Książek, Senior Support Engineer at Severalnines.

When done right, tuning MySQL queries and indexes can significantly increase the performance of your application as well as decrease response times. This is why we’ll be covering this complex topic over the course of three webinars of 60 minutes each.

This blog post will detail the results of Samsung storage in

tpcc-mysql

 benchmark using Percona Server.

I had an opportunity to test different Samsung storage devices under tpcc-mysql benchmark powered by Percona Server 5.7. You can find a summary with details here https://github.com/Percona-Lab-results/201607-tpcc-samsung-storage/blob/master/summary-tpcc-samsung.md

I have in my possession:

• Samsung 850 Pro, 2TB: This is a SATA device and is positioned as consumer-oriented, something that you would use in a high-end user desktop. As of this post, I estimate the price of this device as around $430/TB.

Introduction

The early architecture of Uber consisted of a monolithic backend application written in Python that used Postgres for data persistence. Since that time, the architecture of Uber has changed significantly, to a model of microservices and new data platforms. …

The post Why Uber Engineering Switched from Postgres to MySQL appeared first on Uber Engineering Blog.

As work on WarpSQL (Shard-Query 3) progresses, it has outgrown MySQL proxy.  MySQL proxy is a very useful tool, but it requires LUA scripting, and it is an external daemon that needs to be maintained.  The MySQL proxy module for Shard-Query works well, but to make WarpSQL into a real distributed transaction coordinator, moving the proxy logic inside of the server makes more sense.

The main benefit of MySQL proxy is that it allows a script to "inject" queries between the client and server, intercepting the results and possibly sending back new results to the client.  I would like similar functionality, but inside of the server.

For example, I would like to implement new SHOW commands, and these commands do not need to be …

Percona announces the GA release of Percona XtraBackup 2.4.4 on July 25th, 2016. You can download it from our download site and from apt and yum repositories.

Percona XtraBackup enables MySQL backups without blocking user queries, making it ideal for companies with large data sets and mission-critical applications that cannot tolerate long periods of downtime. Offered free as an …

Networking is critical in MySQL, it is a fundamental resource to manage access to the server from client applications and other replication peers. The behaviour of a containerized MySQL service is determined by how the MySQL image is spawned with “docker run” command. With Docker single-host networking, a MySQL container can be run in an isolated environment (only reachable by containers in the same network), or an open environment (where the MySQL service is totally exposed to the outside world) or the instance simply runs with no network at all.

In the previous two blog posts, we covered the basics of running MySQL in a container and how to build a custom MySQL image. In today’s post, we are going to cover the basics of how Docker …
