On August 20th, 2020 we released v6.1.6 of our Tungsten Clustering and Tungsten Replicator products. On August 17th, 2021, we released v6.1.14. In this blog we take a look back over the last 12 months and highlight some of our key updates and fixes.
This blog is about Bug Hunting. “Battle-tested” is the Continuent Tungsten QA (Quality Assurance) guarantee. Continuent Tungsten is a clustering and replication solution for MySQL and MariaDB used by some of the largest MySQL estates to achieve continuous MySQL operations, locally and globally (HA, DR and Geo Distribution). Besides the stellar support team, and fully-integrated components, customers say: “Stability,” and, “Tungsten just works.”
Continuent provides multiple methods out of the box to monitor the cluster health. It integrates with monitoring and alerting tools like Nagios/NRPE, Zabbix, and Pagerduty. This blog post shows you the thinking behind each included Tungsten Cluster monitoring tool, and when to use which tool.

Doing a search with InnoDB Cluster with DR (Disaster Recovery) yields lots of results, but does it actually work in the enterprise?

For MySQL and MariaDB database clusters, Saas, Fintech and other organizations with mission-critical databases typically require what’s called a managed “composite” cluster, or “cluster-of-clusters.” This blog is about active/active versus active/passive composite clusters for MySQL and MariaDB database systems.

This blog is about troubleshooting failed DDL across all Replicas in a composite active/active (CAA) Tungsten Cluster. The issue was resolved by setting a more permissive SQL_MODE, then locating and cleaning the bad data with proper NULLs before re-issuing the ALTER TABLE.
Welcome to the wonderful world of open source! You really are on your own, even if you think you acquire a solution that works. But many of the companies offering solutions based on open source components wrapped with expensive consulting engagements really can’t help you as they are not the original developers of some of the important core components, thus they do not have the necessary skills to fix them either.Welcome to the wonderful world of open source!

This latest post on MySQL replication follows the ones we did on Amazon Redshift & Amazon Aurora; naturally, we had to cover Amazon RDS as well and so we look here at how to easily and securely replicate from MySQL to Amazon RDS (and vice versa).
Instead of contributing back to the original project, and in that way benefitting the project as a whole, Percona takes over smaller open-source projects (such as Galera) and larger open source projects (MySQL, MongoDB), then adds some small enhancements (especially when compared to the work done by the original developers), slaps its own name on it and proceeds to make some negative comments against those who have done the hardest work.
