Data migration from Oracle to MariaDB with Docker and Connect SE: A Step-by-Step Guide

In this blog we are going to learn how to migrate data from Oracle to MariaDB.

To begin, we’ll learn the basics about Oracle database to have an understanding about the steps that are done on the demo example. After, we will create a table in Oracle and migrate it to MariaDB.

To migrate data from Oracle there are 2 ways:

  1. Dump Oracle data to CSV and load data in MariaDB.
  2. Use the Connect Storage Engine to create or insert into a table from Oracle’s source definition.

For demonstration, we are going to use a docker container with an Oracle Express Edition (XE) image.

MariaDB Coding Standards

Coding standards are often as hotly debated as vim vs emacs and other developer arguments. Viewers of the show Silicon Valley will all know the “tabs vs spaces” scene and how passionate people can be about it. Whilst I do personally have a preference (I’m not sharing it here), I feel it is much more important that people stick to one standard for a code base.

Standards Story

Several months ago a new community developer for MariaDB Server sent me a message asking where to find our coding standards document. After a bit of searching I realised we did not have one, and if we want to onboard new developers we definitely should have one.

Code of Conduct Update

Back in December, we asked for your feedback on implementing a code of conduct in the MariaDB Server community. We have seen some great feedback and observations from this and today we are have published version 1.0 of our code of conduct.

Feedback

The feedback we have received has been generally positive both when it comes to implementing a code of conduct in general, and to the content of the text.

That said, it was suggested by Brian Andrus that we better define “inflammatory language”; this is something we actually discussed internally prior to the draft content.

Ask ChatGPT: MariaDB Performance Tuning: Tips and Tricks

This is the next in the series of posts exploring ChatGPT and its insights about MariaDB. The series began with ChatGPT, OpenAI and MariaDB Foundation, followed by Ask ChatGPT – Getting Started with MariaDB: A Comprehensive Guide for Beginners.

This week’s topic, suggested by ChatGPT itself, was “MariaDB Performance Tuning”. So how did it do?

MariaDB is undoubtedly one of the most popular open-source database management systems available today, with a strong focus on performance and ease of use. Whether you are a developer, database administrator, or an IT professional, ensuring that your MariaDB installation performs efficiently is crucial.

Ask ChatGPT – Getting Started with MariaDB: A Comprehensive Guide for Beginners

This is the next in a series of posts on our explorations with ChatGPT that started with ChatGPT, OpenAI and MariaDB Foundation. Here, we asked ChatGPT to generate a blog post, and Chief Innovation Officer Daniel Black reviewed the results.

“Getting Started with MariaDB: A Comprehensive Guide for Beginners” is the question we asked ChatGPT. What we got is below. Rather than a blog on what you could have done yourself, I’ll look through the answer below and see how accurate it is, what could be better/worse, and assume this is some reflection on the references that the engine was trained on.

MariaDB Foundation at CloudFest Hackathon

On the 18th – 20th of March there was a Hackathon before the CloudFest conference. This had 11 projects and well over 100 participants every team producing something great. In fact, thanks to the Hackathon, there is a new MariaDB Health Checks plugin available for WordPress.

ChatGPT, OpenAI and MariaDB Foundation

When everybody and their grandmother are talking about ChatGPT, you know something is happening – something with significance outside the usual IT bubble. As the first in a series of blog entries, let me reflect upon what AI means for users of MariaDB Server – or, at least, what implications we at the MariaDB Foundation can see at this point in time.

The AI revolution is inevitable …

Pundits say that lawyers or programmers won’t be replaced by AI – but they will be replaced by lawyers or programmers that use AI. I would agree.
