The MySQL High Availability Landscape in 2017 (the Babies)

This post is the third of a series focusing on the MySQL high availability solutions available in 2017.

The first post looked at the elders, the technologies that have been around for more than ten years. The second post talked about the adults, the more recent and mature technologies. In this post, we will look at the emerging MySQL high availability solutions. The “baby” MySQL high availability solutions I chose for the blog are group replication, proxies and distributed storage.

Group replication

Group replication is the Oracle response to Galera. The term “InnoDB cluster” means a cluster using group replication. The goal is offering …

The MySQL High Availability Landscape in 2017 (The Adults)

In this blog post, we’ll look at some of the MySQL high availability solution options.

In the previous post of this series, we looked at the MySQL high availability (HA) solutions that have been around for a long time. I called these solutions “the elders.” Some of these solutions (like replication) are heavily used today and have been improved from release to release of MySQL.

This post focuses on the MySQL high availability solutions that have appeared over the last five years and gained a fair amount of traction in the community. I chose to include this group only two solutions: Galera and RDS Aurora. I’ll use the term “Galera” generically: it covers Galera Cluster, MariaDB Cluster and Percona …

Group Replication: The Sweet and the Sour

In this blog, we’ll look at group replication and how it deals with flow control (FC) and replication lag. 

Overview

In the last few months, we had two main actors in the MySQL ecosystem: ProxySQL and Group-Replication (with the evolution to InnoDB Cluster). 

While I have extensively covered the first, my last serious work on Group Replication dates back to some lab version years past.

Given that Oracle decided to declare it GA, and Percona’s decision to provide some level of Group Replication support, I decided it was time for me to take a look at it again.

We’ve seen a lot of coverage already too many Group Replication topics. There are articles about Group Replication and performance, Group Replication and basic functionalities (or lack of it like automatic node provisioning), Group Replication and ProxySQL, and so on.

But one question kept coming up over and over in my …

The MySQL High Availability Landscape in 2017 (The Elders)

In this blog, we’ll look at different MySQL high availability options.

The dynamic MySQL ecosystem is rapidly evolving many technologies built around MySQL. This is especially true for the technologies involved with the high availability (HA) aspects of MySQL. When I joined Percona back in 2009, some of these HA technologies were very popular – but have since been almost forgotten. During the same interval, new technologies have emerged. In order to give some perspective to the reader, and hopefully help to make better choices, I’ll review the MySQL HA landscape as it is in 2017. This review will be in three parts. The first part (this post) will cover the technologies that have been around for a long time: the elders. The second part will focus on the technologies that are very popular today: the adults. Finally, the last part will try to extrapolate which technologies could become popular in the upcoming years: the …
