When it comes to zero downtime, proxies are the first line components of a cluster. In order to achieve High Availability (HA) for MySQL, MariaDB and Percona Server, a commonly deployed setup consists of configuring load balancers (hardware or software) on top of those proxies.
In this blog post, we describe the new Read Affinity tuning feature of the Tungsten Connector.
Tungsten Connector read affinity now supports multiple dataservices with ordering and exclusion (only one was previously allowed).
You may now fine-tune the affinity per user in user.map and via the global tpm configuration option connector-affinity.
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.
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.
