Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

Has a week passed already? Welcome back to the second column. A lot of time has been spent neck deep in getting speakers accepted and scheduled for Percona Live Open Source Database Conference Europe 2017 in Dublin, as well organizing the conference sponsors.

At the time of writing, we are six weeks away from the conference, so a little over a month! Have you registered yet? …

In this post, we’ll use a blog poll to find out what operating system you use to run your development database servers.

In our last blog poll, we looked at what OS you use for your production database. Now we would like to see what you use for your development database.

As databases grow to meet more challenges and expanding application demands, they must try and get the maximum amount of performance out of available resources. How they work with an operating system can affect many variables, and help or hinder performance. The operating system you use for your database can impact consumable choices (such as hardware and memory). The operating system you use can also impact your choice of database engine as well (or vice versa).

When new projects, new applications or services or testing new architecture …

In this blog, we’ll look at ClickHouse on its one year anniversary.

It’s been a year already since the Yandex team released ClickHouse as open source software. I’ve had an interest in this project from the very start, as I didn’t think there was an open source analytical database that could compete with industry leaders like Vertica (for example).

This was an exciting year for ClickHouse early adopters. Let’s look at what it accomplished so far.

ClickHouse initially generated interest due to the Yandex name – the most popular search engine in Russia. It wasn’t long before jaw-dropping responses popped up: guys, this thing is crazy fast! Many early adopters who tried ClickHouse were really impressed.

Fast doesn’t mean convenient …

I recently attended DevOpsDays Toronto 2017, my first proper DevOpsDaysTO event.  I had the pleasure of attending and being able to immerse myself in this openly collaborative and supportive culture of IT professionals.  The variety of considerations expressed for delivering software features in a rapidly, frequently and reliable release focused manner was really intriguing….but not without its own complexities.… Read More »

Welcome to the third (and final) day of the Percona Live Open Source Database Conference 2017, and the third (and final) set of Percona Live keynotes! The enthusiasm hasn’t waned here at Percona Live, and we had a full house on Thursday morning!

Day three of the conference kicked off with three keynotes talks, and ended with the Community Awards Ceremony:

Spinaltap: Airbnb’s Change Data Capture System

Xinyao Hu (AirBnB)

In this talk, Xinyao introduced Airbnb’s change data change system, Spinaltap. He briefly covered its design, and focused on various use cases inside Airbnb. These use cases covered both online …

In the last post I shared the simple set of steps to configure a Group Replication setup using SQL commands, and a few in the configuration file too. Indeed, it can be simple.  But then there are times where there are more requirements and configurations need more attention. Maybe the OS environment we use for MySQL setups has never impacted us… Read More »

MySQL Cluster is a highly available, distributed, shared-nothing database with very interesting performance characteristics for some workloads. Among other features, it supports automatic sharding and allows us to bypass the SQL layer if we don’t need it, via the NDB API (which in my eyes, makes it one of the few transactional nosql databases out there).

In this post, I’ll describe how we can set up replication from MySQL Cluster into a standalone MySQL server using Innodb as the storage engine.

Introduction

There are a few reasons to set up replication between MySQL Cluster and a non-NDB based MySQL server. These reasons include (but are not limited to): the need …

So you’re interested in the “new” MySQL Group Replication feature but are concerned that configuring it is going to be difficult.  Let me soothe those concerns with this blog post.  Yes, the MySQL team has recently been discussing other methods to configure Group Replication using the RC release of MySQL Shell and how it can be used… Read More »

This blog post examines the recent MySQL® ransomware attacks, and what open source database security best practices could have prevented them.

Unless you’ve been living under a rock, you know that there has been an uptick in ransomware for MongoDB and Elasticsearch deployments. Recently, we’re seeing the same for MySQL.

Let’s look and see if this is MySQL’s fault.

Other Ransomware Targets

Let’s briefly touch on how Elasticsearch and MongoDB became easy targets…
