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?

Continuent is pleased to announce that Tungsten Clustering 6.0.2 and Tungsten Replicator 6.0.2 are now available!

Our 6.0.2 release is a critical bug fix for the cluster Manager logic within a Multimaster cluster.

All current users of v6.0.0 and v6.0.1 should upgrade IMMEDIATELY!

Fixes issue CT-672: the manager could set the master to read-only when performing a switch operation.

There is a procedural work-around if you get into this situation:

Over the years, Tungsten Clustering has grown and matured. Early on, in response to our customers' needs, we introduced the concept of the Passive Witness to allow for clusters with only two nodes. Normally, a cluster requires three nodes to create a voting quorum, which requires an odd number of members to avoid split-brain scenarios. It is the Witness which provides the tie-breaker in the event of a network partition.

We have identified an issue in a script that is executed as part of the Tungsten Clustering solution. The script itself executes a small query against the internal tables used by the replicator in order to help identify the current status and latency of the replication process.
