Tungsten Clustering versus AWS RDS/MySQL

Enterprises require high availability for their business-critical applications. Even the smallest unplanned outage or even a planned maintenance operation can cause lost sales, productivity, and erode customer confidence. Additionally, updating and retrieving data needs to be robust to keep up with user demand.

Let’s take a look at how Tungsten Clustering helps enterprises keep their data available and globally scalable, and compare it to Amazon’s RDS running MySQL (RDS/MySQL).

Replicas and Failover What does RDS do?

Having multiple copies of a database is ideal for high availability. RDS/MySQL approaches this with “Multi-AZ” deployments. The term “Multi-AZ” here is a bit confusing, as enabling this simply means a single “failover replica” will be created in a different availability zone from the primary database instance. …

How To design a better Ansible Role for MySQL Environment ?

In our earlier stage of Ansible, we just wrote simple playbook and ad-hoc command with very long ansible hosts file. When we plan to use Ansible extensively in our daily production use case, we understand that simple playbooks don’t help to scale up to our expectation.

Even though we had options for separate variables, handlers and template files according to our requirements, this un-organized way didn’t help. It looked very messy and made me unhappy when I saw the code too.  That’s the place we decided to use Ansible Role.

My understanding of Ansible Roles?

The role is the primary mechanism for breaking a playbook into multiple files, we can simply refer to the Python Package. Roles help to group multiple tasks, Jinja2 template file, variable file and handlers into a clean directory structure. This will help us to reduce the syntax error while developing and also …

Database Objects migration to RDS/ Aurora (AWS)

The world of application and its related services are migrating more towards cloud, because of availability, Elasticity, Manageability etc. While moving the entire stack we need to be very cautious while migrating the database part.

Migration of DB servers is not a simple lift and shift operation, Rather it would require a proper planning and more cautious in maintaining data consistency with existing DB server and cloud server by means of native replication or by using any third party tools.

The best way to migrate the existing MySQL database to RDS, in my opinion, is by using “logical backup“. Some of the logical backup tools as below,

MySQL to Amazon Redshift Replication.

In our work, We used to get a lot of requirements for replicating data from one data source to another. Our team provided solutions to replicate data from MySQL to Vertica, Amazon Redshift, Hadoop. Out of which Amazon Redshift replication is a bit complicated as Amazon Redshift is a Database as a service (DBaaS) and the process is not straightforward.

So, I take this opportunity to guide on how to replicate the specific set of tables from MySQL to AWS Redshift using Tungsten replicator.

1.0. Tungsten Replicator:

Tungsten Replicator is an open source replication engine supports data extract from MySQL, MySQL Variants such as RDS, Percona Server, MariaDB and Oracle and allows the data extracted to be applied on other data sources such as Vertica, Cassandra, …

MySQL Cluster 7.6GA in the Cloud: the RPM/YUM platform

In this series of blogs I will do my best to demonstrate how to set up and run Cluster in Cloud environment by hand and by utilizing MCC. For detailed configuration, I will use MCC (Auto-installer). Some of the information regarding this setup is provided in post by Mikael. Information regarding Auto-installer is available in our documentation, HTML help files in share/MCC distribution directory and in my blog post.

Cloud setup It might come as surprise but for initial testing any instance should do. I started with 1CPU/1GB RAM ones. The target topology was:

  • Host #1: Management node and Cluster client tools.
  • Host #2: Multi-threaded DATA node. …
