We just published a series of 4 video tutorials about our native, full-stack, out-of-the-box and easy to use High Availability and Scaling solution for MySQL: InnoDB Cluster!

If you want to see the new MySQL Shell 8.0 in action to create a MySQL InnoDB Cluster and try it out yourself, just take a look!…

On March 22, 2018, we held a webinar on how Percona XtraDB cluster 5.7 (PXC) and ProxySQL can help achieve your database clustering high availability needs. Firstly, thanks to all the attendees for taking time to attend the webinar and we are sure you had a webinar experience. We tried answering some of your high availability questions during the call but due to time restrictions if we missed some of the questions then this blog will help clarify them.

Q. You say the replication to servers is virtually synchronous, if there is any latency, does ProxySQL detect this and select a node accordingly?

A. PXC nodes are …

MySQL InnoDB Cluster has proven with the first GA release its potential as the native out-of-the-box HA solution for MySQL. With the second GA release, usability, stability and flexibility were greatly improved as described in the previous blog post.

This tutorial aims to show how does a typical InnoDB cluster setup look like and how that setup even became simpler and more effective as before.…

Introduction

In this post we will explore one approach to MySQL high availability with HAProxy, Consul and Orchestrator.
Let’s briefly go over each piece of the puzzle first:
– HAProxy is usually installed on the application servers or an intermediate connection layer, and is in charge of connecting the application to the appropriate backend (reader or writer). The most common deployment I’ve seen is to have separate ports for writes (which are routed to the master) and reads (which are load balanced over a pool of slaves).
– Orchestrator’s role is to monitor the topology and perform auto recovery as needed.
The key piece here is how we can make HAProxy aware that a topology change has happened, and the answer lies within Consul (and Consul templates).
– Consul is meant to be told the identity of the new master by Orchestrator. By leveraging Consul templates, we can then in turn propagate that …

The MySQL Development Team is proud to announce the second GA release of InnoDB cluster!

We listened carefully to the feedback we got from the previous major release (1.0 GA) and the last release candidate (8.0.4 RC) and incorporated many of the suggested changes.…

The MySQL Development Team is proud and happy to announce the General Availability release of InnoDB Cluster 8.0! This is an extremely exciting release of our integrated, native, full stack High Availability (HA) solution for MySQL.

InnoDB Cluster provides an out-of-the-box and easy to use built-in HA and Scaling solution for MySQL by tightly integrating the following GA components:

…

It is with extreme delight and a big smile on our face that we share the news that a new major MySQL release has been declared Generally Available (GA). The road to MySQL 8 was pretty eventful, sometimes painful and sometimes hard, always challenging, but nonetheless a great ride and an extremely rewarding journey for the engineers that have worked on it.…
