MySQL-Shell has had a set of “Util” object functions for almost a year as of this post. It is this added functionality that negates any reason someone would still need to use the old mysqldump client. It (mysqldump) helped the MySQL Community for a long, long time. It also introduced a large amount of garbage and messiness in… Read More »

Point-In-Time Recovery (PITR) for MySQL databases is an important feature that is essential and covers common use cases, like a recovery to the latest possible transaction or roll-back the database to a specific date before some bad query was executed. Percona Kubernetes Operator for Percona XtraDB Cluster (PXC) added support for PITR in version 1.7, and in this blog post we are going to look into the technical details and decisions we made to implement this feature.

This post summarize the steps on how to deploy Open VPN and configure your VCN to use it.
So, in OCI, we have already some MDS & Compute instances deployed, this is how the dashboard looks like:
We can start by deploying our OpenVPN instance using OCI’s Marketplace:
And you follow the wizard by adding your administrator username and password:
An important step is to use the existing VCN and place the OpenVPN in the public subnet:
And you create the instance:
This blog post was first published on FoggyKitchen.com.
Hello fine gourmets, for my first dish in the FoggyKitchen.com, I decide to present you how to deploy WordPress on OCI using MySQL Database Service aka MDS.
I wrote some Terraform recipes that you can find on my GitHub repository: oci-wordpress-mds.
In this first post, I will show how easy it’s to deploy directly from OCI’s dashboard using Resource Manager’s stack. I will also share the recent additions.
The first think to do is to download the stack in releases from GitHub:
When the zip file is downloaded locally, you can login in …[Read more]
MySQL is the number one open source relational database management system in the world, and is used by millions of developers across all application types. DigitalOcean, a fast-growing cloud provider that’s increasing in popularity amongst the developer community, is a great host to consider for your MySQL deployments. In this article, we’re going to show […]
There are several ways to deploy ProxySQL between your applications and the database servers. A common approach is to have a floating virtual IP (VIP) managed by keepalived as the application endpoint. The proxies have to be strategically provisioned to improve the resiliency of the solution (different hardware, network segments, etc,).
When we consider cloud environments, spreading instances across many availability zones (AZ) is considered a best practice, but that presents a problem regarding VIP handling.
Per definition, VPC subnets have to be created in a specific AZ, and subnet IP ranges can’t overlap with one another. An IP address cannot simply be moved to an instance on a different AZ, as it would end up in a subnet that doesn’t include it.
So in order to use the VIP method, we …[Read more]
MySQL Replication is a very common topology, widely used in
People use it, among others, for High Availability, Read Scalability or Geographic Redundancy.
Another use case is to use MySQL Replication to seamlessly
integrate a newer version of the server in your
Let’s say you are running MySQL 5.7 then you can easily setup a 8.0 instance as a replica of your 5.7.
Extending this idea it is also possible to replicate your MySQL 5.7 (or 8.0 obviously) to a MySQL Database Service instance, the true MySQL PaaS on Oracle Cloud Infrastructure.
The post Replicate from MySQL 5.7 to MySQL Database Service first appeared on dasini.net - Diary of a MySQL experts.
On behalf of the Vitess maintainers team, I am pleased to announce the general availability of Vitess 9. Major Themes # In this release, we have focused on making Vitess more stable after the successful release of Version 8. There have been no major issues reported. So there were no patches released for Version 8. This has allowed us to push further on compatibility and adoption of common frameworks as priorities.
The aim of Percona Kubernetes Operator for Percona XtraDB Cluster is to be a special type of controller introduced to simplify complex deployments. The Operator extends the Kubernetes API with custom resources. The Operator solution is using Percona XtraDB Cluster (PXC) behind the hood to provide a highly available, resilient, and scalable MySQL service in the Kubernetes space.
This solution comes with all the advantages/disadvantages provided by Kubernetes, plus some advantages of its own like the capacity to scale reads on the nodes that are not Primary.
Of course, there are some limitations like the way PXC handles DDLs, which may impact the service, but there is always a cost to pay to get something, expecting to have it all for free is unreasonable.
In this context, we need to …[Read more]
