This post will walk through the step to have seamless migration from Azure for MySQL to MySQL Database Service(MDS) by using MySQL Shell Utility.

If like me you like to share some data between all your devices (presentations, keypassX file, pictures, …), you probably use a cloud platform to store all that.

I do like to keep control of such solution, I used ownCloud and now I’m using Nextcloud.

In this article I will show you how to easily deploy Nextcloud on Oracle Cloud (OCI) using MySQL Database Service (MDS) and Object Storage.

The easiest way to deploy solutions on OCI is to use Terraform and Resource Manager’s Stack.

If you already have an account on Oracle …

It is always hard to select a CPU for your own purpose. You could waste hours reviewing different benchmarks, reviews, and bloggers, and in the end, we would limit all our requirements to performance and price. For performance measuring we already have some specific metrics (e.g. in MHz to some specific tool), however, for economic comparison, it is quite hard.  Mostly we are limited by our budget. Again, for our personal purposes, we are limited only with the cash in our pockets. It is easy to compare only two or three CPUs; it is required just to compare their price and performance and then create a simple bar plot and then check the results. However, what do you do if you have at least three types of CPU, a different number of CPUs cores on board, and seven different scenarios?  It was a challenge to do it for performance, and for economic efficiency, it has become a nightmare. For a one-time purchase, it should be easier than for the …

Apache Zeppelin is a web-based notebook notebook that enables data-driven, interactive data analytics, machine learning, and collaborative documents with SQL, Scala, Python, R. In this article, we explain how to enable HeatWave to accelerate the SQL queries.

A database is a special kind of structured, persistent, global variable with concurrent access over the network.

You write data to a cell of a row of a table in a schema in the server, and it is being kept around for you, with a lifetime longer than the runtime of your program. The database takes care of making sure of ordering access to that data, so there is a clearly defined series of changes to the data – locking, transactions, isolation are things that make databases popular.

And so one gets to have a lot of database schemas in server instances, and they grow. Sometimes that becomes a problem.

Databases don’t scale, even when they scale

These days, the MySQL server can easily utilize the resources even of very large servers. At work, we have taken instances easily up to 400.000 queries per …
