Continuent is very pleased and excited to announce that the new Tungsten Clustering 6.0 and Tungsten Replicator 6.0 are now available for download by our customers. The 6.0 release is the culmination of over a years work within our clustering product in order to improve the functionality and manageability of what we now call our ‘Multimaster Clustering’ solution. This is the replacement for what we called the multi-site, multi-master (MSMM) clustering functionality in earlier releases. The multimaster clustering allows for multiple clusters, in multiple locations, to be linked together into a single composite cluster. Because it’s a composite cluster, you gain all of the functionality that’s already available in a cluster, such as:

• High availability
• Failover
• Automated recovery
• Read-write split
• Maintenance without downtime

But it’s now applied to the …

Codership is pleased to announce the release of Galera Replication library 3.23, implementing wsrep API version 25.

This release incorporates all changes up to MySQL 5.7.21, MySQL 5.6.39 and MySQL 5.5.59, including several fixes to vulnerabilities reported by Oracle in here.

New features and notable fixes in Galera replication since last binary release
by Codership (3.22):

• Write set serialization has been changed to use proper memory alignment in order to avoid crashes on platforms which do not allow unaligned memory access (http://www2.galeracluster.com/e/38852/codership-galera-issues-445/88b8yp/875788176)

Notable bug fixes in MySQL 5.7.21: …

“Our three megastores’ and webshop’s combined revenue was 432 million euros in the year 2017. Galera Cluster has been the cornerstone of the system, secured our sales and supported our growth.”

“MySQL master/slave setup was just too fragile and needed regular work to fix each time the slave got out of sync. Now with Galera we’ve found that even if we take a node offline for a while, it re-syncs automatically and without intervention.”

“The big plus is that all nodes have exact the same information, and no node is running for even a fraction of a second behind. This will also mean that no information will be lost!”

READ MORE CASE STUDIES AND TESTIMONIALS

Use the opportunity to talk to Galera Cluster developers and experts. Visit Galera Cluster booth at Conrad Hotel, New York City February 26-27. We will be happy to answer your questions and verify your Galera deployment plans.

There are many Galera Cluster presentations at the conference.

Global Data Replication with Galera for Ansell Guardian

Greg Henderson and Louis Zircher

Monday 26th, 4:00 pm – 4:50 pm

In early 2017, we seamlessly replaced the global geo-distributed data synchronization …

“We wanted a solution which was backward compatible with our frameworks, as we have used mainly MySQL, which was reliable and nearly 100% data consistent.  If our application were to execute a commit and receive a successful response, we needed a 100% guarantee that we have rows of data in our database — and for more than that one instance.”

There were many options E-CARD explored. “First, we tried MySQL NDB Cluster. That was a very frustrating experience. After that we tried a few other plugins and extensions of MySQL, but they weren’t complete solutions. At the end of this process, we found Galera with MySQL. It responded to our needs nearly 100% of the time.”

in case of unexpected input from ASIO IO service (GAL-518)

* Race condition fixed in GComm message sending codepath (GAL-520)

bug could stall cluster messaging until the next keepalive was sent by
some node, causing …

Since its creation, Galera Cluster has established itself as the most popular high availability solution for MySQL and MariaDB users worldwide.

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).
