This article is the second of the series about configuring a Cassandra Cluster in Azure. In the previous one we completed the installation of Cassandra in a new Virtual Machine (VM) in Azure, this VM will become our template for creating new nodes based on it.  In this article we will be covering the next sections:

• Localize key files
• Configuring our Cluster (cluster name, seed nodes)
• Adding more configuration to Cassandra through yaml file
• Configuring RPC (service, interface, and address)
• Deleting data directory

The Apache Cassandra Database is one of the most growing and so scalable NoSQL technology available in the market with an increasing number of companies around the world using it.  Every time that I start a new professional journey toward learning a new technology, It is so important to me count with the tools and a puppet project which give me the possibility to start practicing and including a realistic scenario where I would have the opportunity of consolidating any new knowledge acquired, hence having a Cassandra Cluster with many nodes is must, mainly because horizontal scaling is one of the main strengths of Cassandra. 

If you are involved in the IT world it is more than sure that you have heard about Python and how so great this programming language is, and I think the keyword is versatile, because effectively it is one of the main benefits than Python give us, and it is thinking in the widespread of it thus push me to start a new series of articles which together with my section “Chronicles from the trenches” I am going to share some stories, tips, tricks, complains and shout out about Python, always seen from the perspective of a Database Engineer that probably someday decide to transition toward Data Engineer role.

This article is part of a series dedicated to showing some examples of Databases common problem and how to address it, this time the turn is for MySQL, a great RDBSM and extremely popular relational system. Here the link to the blog of my company TheWorkshop where I decided to contribute with this series of articles, I hope you enjoy it.
