A robust monitoring setup is essential for cluster health and viability - if your replicator goes offline and you do not know about it, then that Replica becomes effectively useless because it has stale data. This means keeping a close watch on the health of the MySQL / MariaDB / Percona Server database nodes from many perspectives, from ensuring sufficient disk space to testing that replication traffic is flowing.

Tungsten Clustering offers a graphical administration tool called the Tungsten Dashboard™ to help with your management burden. The GUI makes the deployment much easier to visualize and administer.

The Tungsten Replicator is an extraordinarily powerful and flexible tool capable of moving vast volumes of data from source to target.

In this blog post we will discuss one specific aspect of the THL (Transaction History Log) - the METADATA unsafe_for_block_commit flag.

One nice thing about Tungsten Clustering is that you need just a single command to move the master role to another host in your cluster.

Continuent is pleased to announce that Tungsten Dashboard v1.0.1 is now available!

Our Dashboard v1.0.1-36 is a bug fix release that also contains a few improvements. Some of the highlights include:

In this blog post, we discuss failover concepts and administration.

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 will discuss the basics of how to implement and use filters in the Tungsten Replicator.

Managing a single cluster takes time and attention, and handling multiple clusters spread out over many sites is even more demanding. Tungsten Clustering offers a graphical administration tool called the Tungsten Dashboard™ to help with your management burden. You are able to view, monitor and maintain all of your clusters all in one place.

In this blog post we will discuss the internals of the Tungsten Replicator from the perspective of data flow processing.

A pipeline (or service) acts upon data.

Pipelines consist of a variable number of stages.

Think about it - your global, cloud-based application needs to be online and available for the business to run. Downtime is to be avoided like the plague. Perhaps you even have multiple cloud providers to span.

How do we create a database service layer that handles all kinds of failures?
