Blog Poll: What Operating System Do You Run Your Development Database On?

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 …

ClickHouse: One Year!

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 …

Group Replication GCS Troubleshooting

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 »

Asynchronous Replication from MySQL Cluster

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 …

MySQL Ransomware: Open Source Database Security Part 3

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…

Customizing pt-stalk to Capture the Diagnostics Data You Really Need

Valeriy Kravchuk’s great recent post on using oprofile to profile MySQL mentioned how pt-stalk, the script from Percona Toolkit to capture diagnostics data based on a detected condition, currently does not support the new operf comand, and relies instead on the deprecated and soon to be removed, opcontrol.

Fortunately, in the Open Source world, we deal with these situations by contributing, and this seemed a simple enough change that I could get a PR ready quickly and reply …
