The MySQL High Availability Landscape and where Galera Cluster fits in (USA and EMEA Webinar)

The MySQL Server High Availability landscape provides with a slew of tools to help you ensure that your databases keep humming. Such tools are Galera Cluster, however, it is worth looking at semi-synchronous replication with failover tools, and also the usual leader-follower asynchronous replication.

MariaDB OpenWorks was an ocean of Galera Cluster activity

MariaDB OpenWorks happened February 25 – 27, 2019 in New York City. It was filled with plenty of activity.

The keynote by Michael Howard, C.E.O. of MariaDB, is an interesting watch, one with many quoted articles especially around “strip-mining open-source technologies and companies,” and “abusing the license and privilege, and not giving back to the community.” Many articles were written about this topic, and it’s clear that open-source has arrived considering all of the success around the IBM acquisition of Red Hat, the Elastic I.P.O., the Microsoft acquisition of GitHub, the SalesForce acquisition fo MuleSoft and the MongoDB I.P.O.

Seppo Jaakola, the C.E.O. of Codership, talked about …

InnoDB Cluster in a Nutshell Part 3: MySQL Shell

Welcome to the third part of this series. I’m glad you’re still reading, as hopefully this means you find this subject interesting at least. Previously we presented the first two components of MySQL InnoDB Cluster: Group Replication and MySQL Router and now we will discuss the last component, MySQL Shell.

MySQL Shell

This is the last component in the cluster and I love it. Oracle have created this tool to centralize cluster management, providing a friendly, command-line based user interface.

The tool can be defined as an advanced MySQL shell, which is much more powerful than the well known MySQL client. With the capacity to work …

ClusterControl is the go-to automation and management system for Galera Cluster users.

And together, we’re going to walk you through all the different aspects that make Galera Cluster such a popular high availability solution for MySQL and MariaDB and how to best manage it with ClusterControl.

We’ll hear about the latest features of Galera Cluster directly from Codership, the creators of Galera Cluster. And we’ll look at how to automate everything from deployment, monitoring (how about ASCII-art graphs?), backups, failover, recovery, rolling upgrades and scaling using the ClusterControl CLI (for a change, we also have a GUI of course).

Announcing Galera Cluster 5.7.18, 5.6.36 and 5.5.55 with Galera 3.21. Improvements to IPv6 Support, Bug Fixes and Changes to Repositories Structure

Codership is pleased to announce a new release of Galera Cluster for MySQL
consisting of MySQL-wsrep 5.7.18, 5.6.36, 5.5.55 and Galera 3.21, wsrep API
version 25.

Changes to Repositories Structure

With the new release the repository structure is changed to allow for
existence of all of the wsrep-patched mysql versions currently supported:
5.5 through 5.7.

Thus the repository layout requires from the user to adjust his or her
repository configuration to accomodate those changes. In order to have the
MySQL-wsrep and Galera library installed, one would need to add the following
repositories:

1. Galera-3 repository for galera library:
e.g. http://releases.galeracluster.com/galera-3/DIST/

Here DIST is Linux distribution (ubuntu, centos, …).

The latest version of Galera for FreeBSD is available in FreeBSD Ports
