MariaDB

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.

Read about MySQL to MongoDB / MongoDB Atlas replication: what it’s all about, why it’s needed and how it works.

In this short blog post, we examine the impact that setting the Tungsten cluster policy to Maintenance has on the cluster behavior, and specifically the impact on the Tungsten Connector.

Following the most recent releases of the Tungsten Cluster and Tungsten Replicator AMIs, we’ve recorded two getting started videos with some handy tips and tricks on how the AMIs work, how to avail of them … and how to get started with them!

This blog was written in response to a question about the differences between a 3-node MySQL cluster and a 2-node-plus-a-witness MySQL cluster for MySQL high availability (HA).

This is the second blog in our ‘High Noon’ 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 Codership’s Galera and its variants (MariaDB Galera and Percona XtraDB Cluster) as compared to MySQL clusters with Continuent Tungsten, the only complete, fully-integrated solution for highly-available MySQL clustering solution - for any version of MySQL, MariaDB, and Percona Server - on-premises, in the cloud, hybrid-cloud or multi-cloud.

This blog discusses Asynchronous versus Synchronous MySQL replication for MySQL clustering. Synchronous replication is viewed as the ‘holy grail’ of clustering. But unfortunately, when something is too good to be true, it often is. Before the Tungsten cluster solution Continuent built two synchronous replication cluster solutions (m/cluster, uni/cluster), but we abandoned those for good reasons.
