When using cloud native application architectures, Functions have an important role for the business logic without managing any infrastructure. Functions is a serverless platform powered by the Fn Project open source engine.

These Functions are mostly used to create and run different tasks. They can be executed using Fn Project CLI, OCI CLI or a HTTP request.

HTTP requests are useful to invoke Functions from a different service. Usually use to schedule the execution of the function according to a time schedule. Currently, Oracle Cloud Infrastructure does not provide a native mechanism to create time based schedules to execute some jobs like invoking a Function directly …

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 …

On the previous article we saw how to easily deploy Apache Zeppelin on OCI with MySQL using Terraform.

In this article we will see how we can accelerate queries enabling MySQL HeatWave.

Enabling HeatWave

If you used a MySQL Database Service Shape compatible with HeatWave (MySQL.HeatWave.VM.Standard.E3), using the same Resource Manager Stack, you have the possibility to enable HeatWave and deploy a HeatWave Cluster for your MySQL.

The first think to do, is to edit the previous applied stack:

As we used a HeatWave compatible shape, we have the choice to deploy a HeatWave Cluster and we can choose it:

Save and Apply… the HeatWave cluster will be added:

If you …

Apache Zeppelin is a web-based notebook that enables data-driven,
 interactive data analytics, machine learning, and collaborative documents with SQL, Scala, Python, R.

Today we will see how we can deploy Apache Zeppelin on a Compute instance in Oracle Cloud Infrastructure (OCI) using MySQL Database Service (MDS).

You can manually deploy a compute instance and install zeppelin on it then connect to MySQL Database Service or you can use the Terraform modules I’m sharing on GitHub: https://github.com/lefred/oci-zeppelin-mds

Finally you can also deploy all this by just clicking on the follow button to use …

This post is the third and last of a series of articles dedicated to MySQL Database Service (MDS):

• Using MySQL Database Service in OCI – Part 1: creating a MySQL DB System
• Using MySQL Database Service in OCI – Part 2: importing Data to MySQL DB System
• Using MySQL Database Service in OCI – Part 3: faster with MySQL HeatWave !

The goal of this series if to get familiar with MDS, HeatWave and useful MySQL Shell utilities.

We can now start a query on our MDS instance that has been populated with >200M rows:

 SQL > SELECT year, Reporting_Airline,  
              AVG(ArrDelay) AS avgArrDelay …

• Using MySQL Database Service in OCI – Part 3: faster with MySQL HeatWave !

The goal of this series if to get familiar with MDS, HeatWave and useful MySQL Shell utilities.

Before we start, I would like to highlight that the fastest and recommended way to import data to a MySQL DB System in OCI is to use a parallel dump created using MySQL to Object Storage and load it …

The goal of this series if to get familiar with MDS, HeatWave and useful MySQL Shell utilities.

In this first article we will start by creating a MySQL DB System and a Compute instance in OCI. One of the goal is also to see the benefits of HeatWave, so we will start by creating this …

As you know, MySQL 8.0 can be used as JSON Document Store to store your documents without being linked to any schema. You can also use CRUD operations to deal with these documents using the MySQL X DevAPI.

Of course in documents, it’s possible to also store temporal attributes like date, time, datetime, …

Let’s see how we can deal with such attributes.

This is an example of a collection of documents with a datetime attribute createdOn:

As those attributes don’t have a real type, can we use the createdOn attribute as if it was a real datetime field ?

Let’s try to get all the documents have a created data > '2021-12-02':

We can see that the document “dave” has been filtered out. However, we can see that “kenny” and “miguel” are also present… and this is correct as …

I’m active on multiple platforms (mail, slack, forums, …) and often, when people are looking for help, the first 5 or 10 questions are always the same:

• which version of MySQL are you running ?
• which OS ?
• is it in the cloud ?
• which provider ?
• are you using replication ?
• GTIDs ?
• ….

I’ve added to MySQL Shell Plugin repository and plugin called support which provides an output that user can share when looking for MySQL help.

Usually, I’m focusing only in MySQL 8.0, but this plugin works with older versions too (don’t try MySQL 3.23…. it should be compatible from 5.6).

Let’s see an output if I run it locally:

[fred@fedora ~] $ mysqlsh root@localhost -e "support.fetchInfo()" …

MySQL, the world’s most popular open source database, is available as a managed cloud service in Oracle Cloud Infrastructure (OCI) under the name of MySQL Database Service (MDS).

This is the tenth episode of “Discovering MySQL Database Service“, a series of tutorials where I will show you, step by step, how to use MySQL Database Service and some other Oracle Cloud Infrastructure services.

In this episode, we’ll learn how to connect to our MySQL Database Service instance using the Oracle Cloud Infrastructure Cloud Shell.
It provides a pre-authenticated Oracle Cloud Infrastructure CLI and preinstalled developer tools for easily managing Oracle Cloud resources.
