MySQL InnoDB Cluster Disaster Recovery contingency via a Group Replication Replica

Just recently, I have been asked to look into what a Disaster Recovery site for InnoDB Cluster would look like.

If you’re reading this, then I assume you’re familiar with what MySQL InnoDB Cluster is, and how it is configured, components, etc.

Reminder: InnoDB Cluster (Group Replication, Shell & Router) in version 8.0 has had serious improvements from 5.7. Please try it out.

So, given that, and given that we want to consider how best to fulfill the need, i.e. create a DR site for our InnoDB Cluster, let’s get started.

Basically I’ll be looking at the following scenario:

InnoDB Cluster Source site with a Group Replication Disaster Recovery Site.

Now, just before we get into the nitty-gritty, here’s the scope.

Life is already hard enough, so we want as much automated as possible, so, yes, InnoDB Cluster gets some of that done, but there are other parts we will still have …

Comparing Replication Technologies for MySQL Clustering: Part 1

Overview

Clustering provides high availability and disaster recovery, along with the ability to read-scale both locally and globally. Some clusters even provide active/active capabilities, which others have a single master.

Real time database replication is a must for clustering and other key business purposes, like reporting. There are a number of replication technologies available for MySQL, and some are even bundled into various solutions. When choosing a replication methodology, it is paramount to understand just how the data moves from source to target. In this blog post, we will examine how asynchronous, synchronous, and “semi-synchronous” replication behave when used for clustering. Also, we will explore how …

10 Reasons Why Tungsten Clustering Beats the DIY Approach for Geo-Distributed MySQL Deployments

Why does the DIY approach fail to deliver vs. the Tungsten Clustering solution for geo-distributed MySQL multimaster deployments?

Before we dive into the 10 reasons, note why commercially-supported enterprise software is less risky and in fact less costly:

  • The labor time spent building and maintaining a DIY solution costs more than a supported solution that just works.
  • There is documentation, training, support, so your mission-critical process is never dependent upon an irreplaceable individual.
  1. Tungsten Clustering is a complete solution, comprised of the Replicator, Manager and Connector components
    • With DIY, you must first decide the architecture, then select the individual tools to handle each layer of the topology. …

Blog from the Top — What keeps you up at night? Sleep better with Continuent!

Database Administration is a tough, often ungrateful job. Especially if you run a 24/7 business-critical MySQL or MariaDB deployment.

MySQL has proven to be a remarkably solid database which supports billions of dollars in revenue. On some level this very solidity creates a false sense of security. There are many things that can wrong at any given time, whether that is a change to your app, a bug in the database, hardware failure or just simply running out of disk space.

Percona recently conducted a poll: “What keeps you up at night?”

Not surprisingly, “Downtime/HA” is very high on the list.

While there are many challenging issues and tasks that a DBA must deal …
