MySQL replication technology is powerful and flexible. But it doesn’t do everything perfectly all the time. You may experience trouble with the slaves falling behind the master or want to scale horizontally by building new slaves automatically. Or you might need to build a slave without blocking the master database.

All of these goals can be achieved using some powerful tools. Here’s a quick guide to those tools and how to use them.

5 Ways To Fortify MySQL Replication

Here are all the best 5 ways to fortify MySQL replications:

1. Build New Replicas Without Downtime

Something we’re sure you need to do quite often is to build new slaves. You can snapshot from another slave by bringing the slave down, copying its datadir to an alternate machine, updating the server_id and then starting up. However sometimes you have no slave, or your current slaves are serving data.

In those cases, …

MySQL databases are great workhorses of the internet. They back tons of modern websites, from blogs and checkout carts to huge sites like Facebook. But these technologies don’t run themselves.

When you’re faced with a system that is slowing down, you’ll need the right tools to diagnose and troubleshoot the problem.  MySQL has a huge community following and that means scores of great tools for your toolbox.

In this article, we have mentioned 7 ways that will troubleshoot MySQL effectively and efficiently. Let’s explore them below.

7 Ways to Troubleshoot MySQL

Here are 7 ways to troubleshoot MySQL:

1. Use Innotop

Innotop is a great tool for MySQL which despite the name monitors MySQL generally as well as InnoDB usage. It’s fairly easy to install, just download the perl script. Be sure to include a [client] section to your local users .my.cnf file …

So, you’ve been tasked with managing the MySQL databases in your environment, but you’re not sure where to start.

Steps to MySQL Management

Here are the steps that are required for MySQL management as a DBA:

1. Installation

The “yum” tool is your friend.  If you’re using Debian, you’ll use apt-get but it’s very similar. You can do a “yum list” to see what packages are available. We prefer to use the Percona distribution of MySQL.

It’s fully compatible with stock MySQL distribution, but usually a bit ahead in terms of tweaks and fixes. Also, if you’re not sure, go with MySQL 5.5 for new installations. …

There are a lot of considerations for deploying MySQL in the Cloud. Some concepts and details won’t be obvious to DBAs used to deploying on traditional servers.

For this, we have provided eight best practices in this guide that will certainly set you off on the right foot. Let’s explore them below.

8 Practices You Should Follow While Deploying MySQL on Amazon

Here are eight best practices that you must follow while deploying MySQL on Amazon:

1. Replication

Master-Slave replication is easy to setup and provides a hot online copy of your data.  One or more slaves can also be used for scaling your database tier horizontally.

Master-Master active/passive replication can also be used to bring …

There is no need to mention that speed is one of the most sought-after attributes in any database system. Optimizing MySQL for high speed is essential to ensure responsive applications and efficient data processing.

There are basically two best ways to speed up UNION in MySQL – using UNION ALL and using push-down conditions.

In this article, we’ll explore techniques to achieve optimal performance and speed in MySQL.

Ways to Optimize MySQL for High Speed

Here’s a rundown of how to do those optimizations.

1. UNION ALL is much faster than UNION

How does a UNION work? Imagine you have two tables for shirts. The short_sleeve table looks like this:

And long_sleeve another that looks like this:

In today’s data-driven world, ensuring the safety of your valuable data is crucial.

To safeguard this data using MySQL, implementing a robust backup strategy is essential.

For this, we have mentioned ten important things to consider while dealing with MySQL backups. Let’s learn them in detail below.

10 Things You Must Do While Backing Up MySQL

Here are ten important considerations to keep in mind when dealing with MySQL backups.

1. Use Hot Backups

Hot backups are an excellent way to back up MySQL. They can run without blocking your application, and save tons of restore time. Percona’s xtrabackup tool is a great way to do this.  We wrote a how-to on using xtrabackup for hotbackups.

1. Use Logical Backups

Just because we …

This blog was originally published in February 2017 and was updated in September 2023.

In this blog post, I provide an in-depth introduction to MySQL Replication, answering what it is, how it works, its benefits and challenges, as well as reviewing some of the MySQL replication concepts that are part of the MySQL environment (and Percona Server for MySQL specifically). I will finish by also clarifying some of the common misconceptions people have about replication and how Percona can help.

Since I’ve been working on the Solution Engineering team, I’ve noticed that – although information is plentiful – replication is often misunderstood or incompletely understood.
