This is yet another reminder that MySQL 5.6 reaches End of Life status in February 2021.  I have been sending out such reminders since February of 2020. But in my presentations this year when I bring up the 5.6 EOL, there are a lot of users out there that are shocked to hear the news. In one of my November presentations (virtual) I had a very upset audience member who wondered why I was not making more of a big deal out of the EOL date.

    Wikipedia says ""End-of-life" ("EOL") is a term used with respect to a product supplied to customers, indicating that the product is in the end of its useful life (from the vendor's point of view), and a vendor stops marketing, selling, or rework sustaining it. (The vendor may simply intend to limit or end support for the product.)" 

What does this mean those of you running MySQL 5.6 will not be getting bug fixes, will find it much harder to get support, and …

How scheduler and script stand in supporting failover (Percona and Marco example) 

In part one of this series,  I had illustrated how simple scenarios may fail or have problems when using Galera native support inside ProxySQL. In this post, I will repeat the same tests but using the scheduler option and the external script.

The Scheduler

First a brief explanation about the scheduler.

The scheduler inside ProxySQL was created to allow administrators to extend ProxySQL capabilities. The scheduler gives the option to add any kind of script or application and run it at the specified interval of time. The scheduler was also the initial first way we had to deal with Galera/Percona XtraDB Cluster (PXC) node management in case of issues.

How native ProxySQL stands in failover support (both v2.0.15 and v2.1.0)

In recent times I have been designing several solutions focused on High Availability and Disaster Recovery. Some of them using Percona Server for MySQL with group replication, some using Percona XtraDB Cluster (PXC). What many of them had in common was the use of ProxySQL for the connection layer. This is because I consider the use of a layer 7 Proxy preferable, given the possible advantages provided in ReadWrite split and SQL filtering. 

The other positive aspect provided by ProxySQL, at least for Group Replication, is the native support which allows us to have a very quick resolution of possible node failures.

ProxySQL has Galera …

On a previous blog post, we saw how to create an account on the Oracle OCI using the Oracle Cloud Free Tier offer and then how to instal MySQL Server on the Compute instance.
Some weeks later, the new MySQL Database Service (MDS) was out and I can show you now how to install and configure it.

We are talking about the MySQL 8.0 Enterprise Edition on the on Oracle Generation 2 Cloud Infrastructure. For the moment it’s only available on some of the data regions (Frankfurt and London for the EMEA zone), but normally others will be activated …

Django is a popular framework for Python application developers. It includes packages which make tasks like authorization and content administration easier. Django supports a number of databases including MySQL which makes it possible to run a Django application over Vitess without having to change the application code. Let’s take a look at how to combine the strengths of these two open source frameworks. We built this example using Vitess operator. You can see the details of the implementation in the blog post Vitess Operator for Kubernetes.

OCI CLI is a powerful tool that does it all for OCI administration: from creating a compute instance to configuring a Virtual Cloud Network (VCN), from setting up Identity Management Service (IAM) to managing all the different storage flavours. Consult the OCI CLI command reference.

MySQL Database Service (MDS) is not an exception, everything related to the new MySQL Server service running over OCI can be easily managed with a set of commands using OCI CLI, check it here. Starting new DB Systems, creating and managing backups, dealing with …
