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.

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!

Tungsten Replicator is the most advanced heterogeneous real-time data replication solution for MySQL, MariaDB & Percona Server, including Amazon RDS MySQL and Amazon Aurora. It provides high-performance and improved replication functionality over the native MySQL replication solution and into a range of target databases.

Following the announcement late last year that we’d made our flagship product Tungsten Cluster available on the Amazon Marketplace in an easy-to-access and deploy AMI format, we published some useful resources in the past few months to help users getting started with Tungsten Clustering in the AWS cloud.

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).
