Codership is pleased to announce a new Generally Available (GA) release of the multi-master Galera Cluster for MySQL 5.7 and 8.0, consisting of MySQL-wsrep 5.7.34 (release notes, download) and MySQL-wsrep 8.0.25 (release notes, download) with Galera replication library 3.34 (release notes, download) implementing wsrep API version 25 …

Codership first released a version of MySQL 5.7 with the audit log plugin back when Galera Cluster for MySQL 5.7.30 was released back in June 2020. More recently, we also added the audit log plugin to Galera Cluster for MySQL 5.6.51 in April 2021, but I guess the most important was that we also started including it in Galera Cluster for MySQL 8.0.21 too. We also started supporting it across various distributions, including Debian. For today’s exercise, we will use Galera Cluster for MySQL 8.0.23 on CentOS 7 (compatible with Red Hat Enterprise Linux 7). …

We talk a lot about Galera Cluster for MySQL being great for High Availability, but what about Disaster Recovery (DR)? Database outages may occur when you lose a data centre due to power outages or natural disaster, so why not plan appropriately in advance?

In this webinar, we will discuss the business considerations including achieving the highest possible uptime, focus on business impact, risk mitigation, and disaster recovery itself. What scenarios are right for you: fully synchronous replication across various data centres? A mix of synchronous and asynchronous to an offsite location?

We will discuss Galera Cluster, mixed setups, the use of proxies, and also evaluate some third party solutions. We will debunk claims about how Galera Cluster might not work across data centers, tell you how to successfully do this across data centres, with performance tuning settings for all the segments. Galera 4 has also been released, making …

Just last week we had a Galera Cluster for MySQL streaming replication feature deep dive webinar, by the person that implemented it – Seppo Jaakola. In fact, if you haven’t already read the entire story, we encourage you to read: Galera Streaming Replication: Too Big A Bite Can Choke Your Cluster. We also have the 60 minute video recording for reference.

A huge number of Galera Cluster users have always complained about having issues with large transactions (where writes hang but reads are OK), and we are certain that the correct usage of streaming replication is what will ease that burden. What constitutes a large transaction? Typically when you make big number of …

A significant improvement has come to Galera Cluster 4 for MySQL, in the form of streaming replication. When you are dealing with large (greater than 2GB in size) or long running transactions, previous releases of Galera Cluster would reject the transaction; in the current release transactions can be split into fragmented chunks and those rows can be replicated in chunks to the other nodes even before commit. This is the feature that will remove you from all cluster stall issues due to large transaction processing!

While disabled by default, you can use it and configure it dynamically, and there is also the ability to monitor streaming replication progress. Come to this webinar to learn from the primary author, Seppo Jaakola, on why he implemented the feature, how you can use it, finding the optimal fragment size based on workload, and the design trade-offs for the initial release in where the focus was more on functionality over …
