Recently, a customer asked us:
Why would heavy disk IO cause the Tungsten Manager and not MySQL to be starved of resources?
For example, we saw the following in the Manager log file tmsvc.log:
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.
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.
We are pleased to announce that Tungsten Clustering and Tungsten Replicator GA versions 7.0.1 are now available. This new minor release includes 52 new features and improvements, including two critical bug fixes. Read this blog to learn about the new v7.0.1 release!
