Standards allow modern systems to advance, and the REST specification is one very important example. Since this post is about the Tungsten API in specific, let me simply say this - a RESTful API adheres to six principles: Client-server, stateless, cacheable, uniform interface, layered system and optionally code on demand. As part of the watchability/monitoring goal, our software as of version 7.0.0 includes a proper RESTful API - what we call APIv2. This API is fully documented and public.

Prometheus and Grafana are open source tools that can be used for monitoring MySQL clusters. Prometheus can be used to collect metrics from MySQL clusters, and Grafana can be used to visualize the metrics. Starting with Tungsten v7, using the new Tungsten Prometheus Exporter feature, it’s become easy to leverage the best these powerful monitoring tools have to offer.

This blog is an announcement about a new Webinar. The speaker, Matthew Lang, is the Director of Customer Success for the Americas at Continuent. He covers the significance of this exciting major release in context of previous major releases, and some of the highlights and main benefits.

Transaction History Log (THL) files are the core of Tungsten Replication, containing the actual MySQL write events that are replicated to the replicas. These files can take up considerable amounts of disk space, making them of interest for housekeeping operations to limit the consumption and ultimately, the cost. This blog post will walk you through THL management, along with the new command `tpm purge-thl` which helps automate the process when THL needs to be removed prior to the automatic rotation window.

Thinking transparent reconnects of applications is the grail of HA? It is! But Active/Active setups make them risky.

Sometimes you really, really want to know what a MySQL client is asking of the MySQL server. As of Tungsten Clustering v7.0.0, you may now enable Connector Audit Logging, which captures data transferred between client applications and MySQL servers to a file, database or socket. This blog post will walk you through the feature and how to enable, configure and disable Tungsten Connector Audit Logging.

In this post we will explore a new command in v7.0.1, tpm report. The purpose of tpm report is to provide easy access to all of the settings that pertain to a specific topic. Since Security is a high priority at Continuent, the current default (and only) topic is the Security stance. The tpm report command will evolve and grow over time. This first version is Continuent’s way of providing as much transparency about Tungsten Cluster Security as possible.

We are pleased to announce that Tungsten Clustering and Tungsten Replicator GA version 6.1.17 are now available. Tungsten allows enterprises running business-critical MySQL database applications to cost-effectively achieve continuous global operations with commercial-grade high availability (HA), geographically redundant disaster recovery (DR) and geographically distributed active/active.

In our last blog post on this topic we covered the basics of the new REST  API available with Tungsten version 7.0.0. In this post, Part 2, we explore the REST API in more detail, including payloads and advanced functionality. The API provides a vast pool of capabilities, and here we barely scratch the surface of what can be accomplished.

We are pleased to announce that Tungsten Clustering and Tungsten Replicator GA versions 7.0 are now available. This new major release includes the Tungsten RESTful API (API v2.0), enhanced security, monitoring, performance, management, new commands, a new and improved Dashboard, and new Dynamic Active/Active (DAA) topology. Tungsten v7.0 is the culmination of years of planning and work, and it lays the foundation for even more pinnacle developments. Read this blog to learn about the new v7 release!

This is the third post in a short series about Tungsten Clustering topologies. In this post we will highlight the key differences between Composite Active/Passive, Composite Active/Active (CAA), and the newly available Dynamic Active/Active topology. In short, DAA blends the simplicity of CAP with the automated continuous operations of CAA.

Prometheus is one of the more popular ways to monitor your resources, and starting with version 7.0.0, Continuent has embedded the Prometheus exporter functionality into our core MySQL and MariaDB clustering products. This blog post covers how to enable the exporters, getting metrics and what metrics are available, along with cli tools, customizing the config, documentation references and a little bit about Grafana Dashboard for Tungsten Clusters.
