To copy a MySQL server to another server or to the cloud, there are several ways.

We can distinguish between two different types of copy:

• physical copy
• logical copy

The physical copy is often the fastest. However, it requires some tools to ensure that you have a consistent online backup. For example, you can use MySQL Enterprise Backup (MEB).

Alternatively, it’s possible to use the CLONE plug-in to provision a new instance with existing data from a source server. This is my preferred approach.

Finally, the last physical solution is the use of a file system snapshot, but this requires the right infrastructure and even more care to have a consistent …

Recently I wrote an article on how to define a backup policy for MySQL Database Service in OCI using Terraform. We saw that it was possible to define tags (defined_tags and freeform_tags) in the backup_policy section of a oci_mysql_mysql_db_system resource.

However, it seems that these tags are never used for manual or automated backups in the MySQL Database Service backup process. In the strategy implemented on OCI, the backups inherit the tags from the MySQL DB system itself.

This means that if you want to have some custom tags on your backups, you need to specify them in the MySQL Database resource like this (on line 12):

resource "oci_mysql_mysql_db_system" "MDSinstance" {
    admin_password = var.admin_password
    admin_username = …

In the world of the Databases, one of the most important value that we are all trying to achieve is High Availability. Not to loose our valuable data or in case one server fails to always have another to step in and take control.

So, it is critical to have along with our primary database, other identical instances, the replicas.

On this blog post, we will see the most famous ways to set up our replication.

The post Setting up Replication with various methods for MySQL 8 first appeared on dasini.net - Diary of a MySQL experts.

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 …

With this post we are reaching the end of our journey to HA for WordPress & MySQL 8.0 on OCI.

If you have not read the two previous articles, this is just the right time.

• MySQL 8.0 InnoDB ReplicaSet with WordPress in OCI
• MySQL 8.0 InnoDB ReplicaSet with WordPress in OCI – part II

We started this trip using the MySQL InnoDB ReplicaSet where only 2 servers are sufficient but doesn’t provide automatic fail-over.

In this article we will upgrade our InnoDB ReplicaSet to …

Today’s article is again related to WordPress and MySQL 8.0. We will see how we can setup MySQL InnoDB ReplicaSet and configure WordPress to split the load using both MySQL Instances: we will split reads and writes between the Primary and the Secondary member of our ReplicaSet.

This will be the first part of our journey to achieve HA for our WordPress site on OCI and using all MySQL Servers we have deployed. We don’t want to have a server idle just waiting to take over in case of an incident.

MySQL InnoDB ReplicaSet

First some words about MySQL InnoDB ReplicaSet.

The ease of use of …

As you know, Oracle Cloud Infrastructure (aka OCI) becomes more and more popular. You can find OCI data centers almost everywhere and the price is very attractive.

Something very interesting is the possibility to have different availability domains but also different fault-domains in the same availability one !

Oracle provides a lot of modules to deploy your architecture on OCI using Terraform. Those are called oracle-quickstart repos. You can find them on Github.

There is an official Reference Architecture for MySQL InnoDB Cluster in OCI that I encourage you to read before deploying your MySQL HA solution …

What a great event ! I got very positive feedback for this extended preFOSDEM MySQL Day 2020.

Before my summary, I wanted to thank again all speakers and attendees. Without you this event won’t even exist. And thank you to ICAB for hosting us yet another time !

As you may know, we had 2 parallel tracks for 2 consecutive days. We had very valuable technical content from the MySQL developers and also from the external community members who talked about their favorite database.

There was a large interest in MySQL NDB Cluster and it was obvious that the nice presentations we had, encouraged people to try the worlds highest performance open source in-memory database (and they can even test it on their laptop with DBDeployer). The NDB users were also happy with the new stuff and impressive numbers that Bernd …

The schedule of the preFOSDEM Day is now available !

We had a lot of proposals to deal with. Also this is a MySQL event where we, the MySQL Team has the possibility to show to you, our Community, all what we have working on to improve MySQL but also new stuff. We also invite some of our friends from the MySQL Community to talk about their experience.

I think we did a good selection and propose you new content. We are extremely happy to have Saverio Miroddi from TicketSolve talking about MySQL 8.0, Uber talking about InnoDB Cluster, and Facebook about Binlog.

As you can see, we will have 2 rooms, where one will be dedicated mostly to SQL and Optimizer topics but also tutorials.

You can also see that this year we also want to put some spot lights to MySQL NDB Cluster. You will see what is it, how is it used and what’s new. We will also have 2 community speakers sharing their MySQL NDB knowledge: Giuseppe Maxia, …
