In this blog post, we talk about how to run applications across multiple clouds (i.e. AWS, Google Cloud, Microsoft Azure) using Continuent Clustering. You want your business-critical applications to withstand node, datacenter, availability-zone or regional failures. For SaaS apps, you also want to bring data close to your application users for faster response times and a better user experience. With cross-cloud capability, Continuent also helps avoid lock-in to any particular cloud provider.

The key to success for the database layer is to be available and respond rapidly.

From both a business and operational perspective, spreading the application across cloud environments from different vendors provides significant protection against vendor-specific outages and vendor lock-in. Running on multiple platforms provides greater …

In this blog post, we demonstrate how to convert a single standalone cluster into a Composite Primary/DR topology running in two data centers.

Our example starting cluster has 5 nodes (1 master and 4 slaves) and uses service name alpha. Our target cluster will have 6 nodes (3 per cluster) in 2 member clusters alpha_east and alpha_west in composite service alpha.

This means that we will reuse the existing service name alpha as the name of the new composite service, and create two new service names, one for each cluster (alpha_east and alpha_west).

Below is an INI file extract example for our starting standalone cluster with 5 nodes:

[defaults]
...

[alpha]
connectors=db1,db2,db3,db4,db5
master=db1
members=db1,db2,db3,db4,db5
topology=clustered

To convert the above configuration to a Composite Primary/DR:

1. First you must stop all services on all existing nodes:

   shell> stopall

Missed our Continuent Clustering 6.0 webinar and technical deep dive? Don’t sweat it. Watch these recordings of our presentations and find out what’s new and latest for multisite, multimaster clustering, what’s changed, improvements that we’ve made under the hood, and how this will improve the quality and support for your multimaster MySQL/Percona/MariaDB deployments.

In our technical deep dive, we take a detailed look at the new deployment model, how the different components work together, and how you can now manage and support your new multimaster environment using Continuent Clustering 6.0. We cover the new integration of the replication, how that affects your deployment, and how that alters …

We have identified an issue in a script that is executed as part of the Tungsten Clustering solution. The script itself executes a small query against the internal tables used by the replicator in order to help identify the current status and latency of the replication process. We believe this script may occasionally fail under some very specific conditions, which would not normally be an issue, but the knock on effect is to create Out of Memory errors and instability in the way identifying the current replication state is handled.

The issue has been fixed in the upcoming 6.0.1 and 5.3.2 releases, but we have identified that customers on versions of the Tungsten Clustering solution from v4.0 upwards would benefit from using an updated version of the script.

If you are using Tungsten Clustering 4.x or higher, it is recommended that you apply this patch to improve the stability of your clustering …

Continuent are pleased to announce that the new 5.3.1 release is now available for all our customers.

This is a key bug fix and feature release, the key component of which is the final piece of the support for extracting data types from MySQL 5.7 with the Geometry data type.

Key improvements within Tungsten Clustering:

• Full Support for MySQL data types with the addition of Geometry datatype
• Fixed an issue where large memory dumps could be collected during a failure
• Fixed some issues to ensure compatibility with upcoming products

Key improvements within Tungsten Replicator:

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

It’s important to note that due to the addition of support for the geometry datatype, THL written with Geometry data will no longer be readable by …
