ProxySQL in its versions up to 1.x did not natively support Percona XtraDB Cluster (PXC). Instead, it relied on the flexibility offered by the scheduler. This approach allowed users to implement their own preferred way to manage the ProxySQL behaviour in relation to the Galera events.
From version 2.0 we can use native ProxySQL support […]
… or what I should keep in mind in case of disaster
To retrieve and maintain in SQL format the definition of all tables in a database, is a best practice that we all should adopt. To have that under version control is also another best practice to keep in mind.
While doing that may seem […]
Let’s talk about MySQL high availability (HA) and synchronous replication once more.
It’s part of a longer series on some high availability reference architecture solutions over geographically distributed areas.
Part 1: Reference Architecture(s) for High Availability Solutions in Geographic Distributed Scenarios: Why Should I Care?
Part 2: MySQL High Availability On-Premises: A Geographically Distributed Scenario
The Problem
A question I often […]
In this article, we’ll look at an example of an on-premises, geographically distributed MySQL high availability solution. It’s part of a longer series on some high availability reference architecture solutions over geographically distributed areas.
Part 1: Reference Architecture(s) for High Availability Solutions in Geographic Distributed Scenarios: Why Should I Care?
Percona consulting’s main aim is to identify simple […]
In this series of blog posts, I’m going to look at some high availability reference architecture solutions over geographically distributed areas.
The Problem
Nowadays, when businesses plan a new service or application, it is very common for them to worry about ensuring a very high level of availability.
It doesn’t matter if we are talking about […]
MySQL Resource Groups, introduced in MySQL 8, provide the ability to manipulate the assignment of running threads to specific resources, thereby allowing the DBA to manage application priorities. Essentially, you can assign a thread to a specific virtual CPU. In this post, I’m going to take a look at how these might work in […]

Let them stay together.
In the last YEARS, I have seen quite often that users, when installing a product such as PXC, instead of spending five minutes to understand what to do just run
iptables -F and save.
In short, they remove any rules for their firewall.
With this post, I want to show you how easy […]
In this blog post, I’ll look at how you can use ProxySQL with AWS Aurora to further leverage database performance.
My previous article described how easy is to replace the native Aurora connector with ProxySQL. In this article, you will see WHY you should do that.
It is important to understand that aside from the basic […]
In this post, we’ll look at how to implement ProxySQL with AWS Aurora.
Recently, there have been a few discussions and customer requests that focused on AWS Aurora and how to make the various architectures and solutions more flexible.
Flexible how, you may ask? Well, there are the usual expectations:
How do you improve resource utilization?
How […]
In this blog post, we’ll look at ProxySQL firewalling (how to use ProxySQL as a firewall).
Not long ago we had an internal discussion about security, and how to enforce a stricter set of rules to prevent malicious acts and block other undesired queries. ProxySQL came up as a possible tool that could help us in […]
