There are two key elements (which often separate us from many other open source operators, such as Percona) to our MySQL HA/DR and Continuous Operations solutions. Read this blog, adapted from the June “Word from the CEO” from the Continuent Newsletter to find out what distinguishes Continuent’s Tungsten Clustering solution in the open source MySQL database industry.

We often hear that asynchronous replication creates a possible data loss window, thus it is not an acceptable solution for certain types of applications.

Yes, this is true. In theory, that is. 

In practice, we have developed the Tungsten Cluster solution to the point that it really does not happen in real life. Please read this blog to understand why not!

Customers often use AWS to deploy MySQL or MariaDB Tungsten Clusters. This blog is about changing an AWS instance type from t2.large to t3.large specifically on Amazon Linux 1. It contains the steps to follow when changing AWS instance families to use enhanced networking.

SmartScale is a special mode of the Tungsten Connector (aka Tungsten Proxy), which allows read requests to be intelligently routed to either a replica or the primary to ensure that the data returned is not stale. This feature is available when the Connector is running in the application-layer Proxy mode. Learn more about the behavior of SmartScale in this blog.

Application performance and MySQL database responsiveness is always high priority for highly-available, business-critical use cases. That’s why Tungsten Clustering offers features and options to tune for maximum performance, such as Parallel Apply. When does Parallel Apply work best? What are the limitations? To find out, read this blog from MySQL industry vet, Eric M. Stone, the COO of Continuent!

This blog is about open source MySQL clustering software, specifically Codership’s Galera Cluster and Percona’s fork of that, XtraDB Cluster. If you are considering using Galera, please use the original version, or please use the version by MariaDB, which is actively supporting the Galera team.

Upgrades are a normal, expected part of all software lifecycles, and Tungsten is no exception. Keep your software up-to-date to ensure compatibility, supportability and the lowest risk possible to your operation.

It goes without saying that database security is top priority at Continuent; Tungsten Clustering customers in financial and healthcare organizations among others implement the strictest standards of data security, and so we have always kept it a mandate to not only support HIPPA and PII compliance, and maintain strict boundaries and protocols in design of our software solution and when providing support.

This blog post looks at the ins and outs of Amazon Aurora replication and how to best go about that; including all the details you need to replicate to and from Aurora with the Tungsten Replicator AMI.

Migrating from Galera to Tungsten Clustering is easy with the tools provided by Tungsten Clustering. Because replication happens in the background, applications can stay online with a quick cutover to Tungsten Clustering when ready.

This is the next blog in our competitor comparison series in which we look at the main solutions for MySQL high availability, disaster recovery and geographic distribution. Here we focus on highly available, geo-scale, multi-region MySQL for mission-critical sites and apps with ClusterControl as compared to MySQL clusters with Continuent Tungsten, the only complete, fully-integrated clustering solution for MySQL - on-premises, in the cloud, hybrid-cloud or multi-cloud.

Disasters are waiting to happen. Like OVH data center fire on March 9, 2021. Do you have a solid MySQL Disaster Recovery (DR) plan in place to activate when the time inevitably comes?

If not, Continuent is happy to review your current MySQL HA/DR deployment and to recommend possible changes that might be recommended. Naturally, free of charge.
