Tungsten Replicator is a powerful tool with many great features, and today we will look at a new one - the ability to Pause and Resume a replication service. Until now, the only way to stop a replication stream was to take the service offline, and put it back online when it is needed again. The online process involves a number of internal steps and overhead, and if there are many THL files on disk, it could take some time to index them all before the service can come fully online. To remove the overhead of the startup time, the new pause/resume feature was developed for the Replicator, and is accessed via the `trepctl` command.
We are pleased to announce that Tungsten Clustering and Tungsten Replicator GA version 6.1.18 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.
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+ and the new Tungsten APIv2, 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.
In this blog, we discuss Galera Cluster and synchronous versus asynchronous replication. We also discuss some of the differences between Galera Cluster and Tungsten Cluster rooted in this difference in foundation. And how Tungsten has served a critical niche - mission-critical, geo-distributed, highly-performant MySQL applications - for a long time.
In this blog we take a look at how you can use Tungsten Replicator to replicate data from multiple sources, and merge into a single target using 3 simple yet effective filters.
Migrating to the cloud with zero downtime is a problem that companies running mission-critical applications have to solve, but not on their own. If you’re running a MySQL or MariaDB database it can be easy. Many of our customers have done this successfully, simplifying their overall Cloud migration process by making the database layer easy to move. It’s one less thing to worry about.
In this blog, we cover tprovision. tprovision is a complete rewrite of the provisioning tool “tungsten_provision_slave,” included with Tungsten Cluster. It is streamlined and allows easy provisioning of replica databases.
Tungsten Clustering is a powerful tool with many moving parts, including the Tungsten Connectors which may be installed on any application server. During a troubleshooting event, it is helpful to understand what to look for and where, in addition to understanding how the logs work together to provide a clear picture of the situation. In Tungsten version 7, we introduced a number of features designed to make troubleshooting easier, and this blog will cover some of that too.
Tungsten Clustering allows for many types of maintenance to happen with no downtime at all. This blog post will explore how to upgrade the actual MySQL Server on all cluster nodes with zero downtime.
