Clustering

In this blog post, we talk about how to run applications across multiple clouds (i.e. AWS, Google Cloud, Microsoft Azure) using Tungsten Clustering. You want your business-critical applications to withstand node, datacenter, availability-zone or regional failures. For SaaS apps, you also want to bring data close to your application users for faster response times and a better user experience. With cross-cloud capability, Tungsten also helps avoid lock-in to any particular cloud provider.

This distributed topology, perfect for multi-region SaaS models, allows you to have all the benefits of high availability with centralized writes and local reads for all regions. Latency is limited only by the WAN link and the speed of the target node.

In this blog post, we demonstrate how to convert a single standalone MySQL cluster into a Composite Primary/DR topology running in two data centers.

In this blog post, we talk about what happened during an installation of the Tungsten Cluster into an environment with SELinux running and mis-configured.

In this blog post, we talk about how to configure automatic start at boot time for the Tungsten Clustering components.

By default, Tungsten Clustering does not start automatically on boot. To enable Tungsten Clustering to start at boot time, use the deployall script provided to create the necessary boot scripts:

Tungsten Connector is an essential part of Tungsten Clustering for MySQL, MariaDB, and Percona Server. In this blog post, we talk about the Automatic Reconnect feature in the Tungsten Connector. Automatic reconnect enables the Connector to re-establish a connection in the event of a transient failure.

In this blog post, we talk about how existing client connections are handled by the Tungsten Connector when a manual master role switch is invoked and how to adjust that behavior. Tungsten Connector is an intelligent proxy that serves an essential role in Tungsten Clustering for MySQL, MariaDB, and Percona Server.

The Tungsten Connector is an intelligent MySQL proxy that provides key high-availability and read-scaling features. This includes the ability to route MySQL queries by inspecting them in-flight.

Tungsten Connector is an intelligent proxy used in Tungsten Clustering for MySQL / MariaDB / Percona Clustering. In this blog post, we talk about how query connections are handled by the Tungsten Connector, especially read-only connections.

This blog post covers global MySQL / MariaDB / Percona Server clustering with Active/Active meshed replication, the architecture commonly used for globally-distributed SaaS companies.

What if I want the cluster to be less sensitive to network, especially WAN latency?
