Key improvements within Tungsten Clustering:

  • Full Support for MySQL data types with the addition of Geometry datatype

Tungsten Clustering 6.0 and Tungsten Replicator 6.0 are now available!

Continuent is very pleased and excited to announce that the new Tungsten Clustering 6.0 and Tungsten Replicator 6.0 are now available for download by our customers. The 6.0 release is the culmination of over a years work within our clustering product in order to improve the functionality and manageability of what we now call our ‘Multimaster Clustering’ solution. This is the replacement for what we called the multi-site, multi-master (MSMM) clustering functionality in earlier releases. The multimaster clustering allows for multiple clusters, in multiple locations, to be linked together into a single composite cluster. Because it’s a composite cluster, you gain all of the functionality that’s already available in a cluster, such as:

  • High availability
  • Failover
  • Automated recovery
  • Read-write split
  • Maintenance without downtime

But it’s now applied to the …

New Continuent Webinar Wednesdays and Training Tuesdays

We are just starting to get into the swing of setting up our new training and webinar schedule. Initially, there will be one Webinar session (typically on a Wednesday) and one training session (on a Tuesday) every week from now. We’ll be covering a variety of different topics at each. Typically our webinars will be about products and features, comparisons to other products, mixed in with product news (new releases, new features) and individual sessions based on what is going on at Continuent and the market in general. Our training, by comparison, is going to be a hands-on, step-by-step sequence covering all of the different areas of our product. So we’ll cover everything from the basics of how the products work, how to deploy them, typical functionality (switching, start/stop, etc), and troubleshooting. All of the sessions are going to be recorded and we’ll produce a suitable archive page so that you can go and view the past sessions. Need a …

Kafka Replication from MySQL and Oracle

Hello again everybody.

Well, I promised it a couple of weeks ago, and I’m sorry it has been so long (I’ve been working on other fun stuff in addition to this). But I’m pleased to say that we now have a fully working applier that takes data from an incoming THL stream, whether that is Oracle or MySQL, and converts that into a JSON document and message for distribution over a Kafka topic.

Currently, the configuration is organised with the following parameters:

  • The topic name is set according to the incoming schema and table. You can optionally add a prefix. So, for example, if you have a table ‘invoices’ in the schema ‘sales’, your Kafka topic will be sales_invoices, or if you’ve added a prefix, ‘myprefix_schema_table’.
  • Data is marshalled into a JSON document as part of the message, and the structure is to have a bunch of metadata and then an embedded record. You’ll see an …

Replication between Tungsten clusters

Replication between Tungsten clusters

The process I will describe in this post will allow you to configure replication between Tungsten clusters. The most common use case I have seen for this is a dedicated ETL cluster.

The setup will look like this:

 

So we will have a composite datasource (compositeprod) composed of east and west clusters, and two ETL clusters, one on each side.

The described setup allows failover or switchover within a single datacenter (e.g. db1.east -> db2.east) or to the Disaster Recovery Site, (e.g. db1.east -> db1.west) for the core cluster.

At the time of this article’s publication it is not possible to replicate between two composite clusters, so each ETL cluster needs to be standalone. This feature is expected for Tungsten 5.0 release.

We will install a standalone replicator on the ETL hosts to bring data in …
