You might be used to SHOW GLOBAL STATUS LIKE 'wsrep_%'; from the command line, but why not take a look at all of this on a graph, over time, within the GUI of the Galera Manager? What happens when you feel a node is getting overwhelmed? You tend to check wsrep_flow_control_paused, which returns the percentage of time the node was paused because of Flow Control (normally you do this after a FLUSH STATUS however now you …[Read more]

Codership is proud to announce the first Generally Available (GA) release of Galera Cluster 4 for MySQL 8 and improve MySQL High Availability a great deal. The current release comes with MySQL 8.0.19 and includes the Galera Replication Library 4.5 with wsrep API version 26. You can download it now (and note that we have packages for various Linux distributions).
Galera 4 and MySQL 8.0.19 have many new features, but here are some of the highlights:
- Streaming replication to support large transactions by splitting transaction replication then applying them in smaller fragments. You can use this feature to load data faster, as data is written to all nodes simultaneously (or not at all in case of a failure in any single node).
- Improved …

We have even published Installing a Galera Cluster on AWS guide for Geo-distributed MySQL Multi-master clustering which covers how to install a 3-node Galera Cluster on CentOS 7 to achieve disaster recovery . It turns out, Amazon Linux 2 tends to be quite compatible with this article ( …[Read more]
