During the last MySQL & HeatWave Summit, Wim Coekaerts announced that a new optimizer is available and is already enabled in MySQL HeatWave. Let’s have a quick look at it and how to use it. The first step is to verify that Hypergraph is available: The statement won’t return any error if the Hypergraph Optimizer […]

MySQL Enterprise Monitor, aka MEM, retired in January 2025, after almost 20 years of exemplary service! What’s next? Of course, plenty of alternatives exist, open source, proprietary, and on the cloud. For MySQL customers, we provide two alternatives: This post focuses on the latter, as there is no apparent reason to deploy an Oracle Database […]

In the previous post, we saw how to deploy MySQL HeatWave on Amazon. Multicloud refers to the coordinated use of cloud services from multiple providers. In addition to our previous post, where we deployed MySQL HeatWave on Amazon, we will explore how to connect with another cloud service. Oracle has partnered with Microsoft to offer […]

At the beginning of the year, we released MySQL 9.2, the latest Innovation Release. Sorry for the delay, but I was busy with the preFOSDEM MySQL Belgian Days and FOSDEM MySQL Belgium Days. Of course, we released bug fixes for 8.0 and 8.4 LTS, but in this post, I focus on the newest release. Within […]

The MySQL Belgian Days are sold-out, our event that will take place the 1st and 2nd February 2024 in Brussels seems to have already attracted a lot of interest.

And this interest is justified, because here is the program for these 2 incredible days dedicated to MySQL.

Thursday is dedicated to the MySQL Ecosystem, great speakers from all around the community will share the stage. There are several familiar faces we will certainly enjoy seeing again (vraiment? oui oui!)*.

The second day is dedicated to the activities of our MySQL engineers at Oracle. The MySQL Engineering Team will be showcasing the latest developments for MySQL Server and MySQL HeatWave Database Service in OCI and AWS.

Day 1 – MySQL …

We already saw how to deploy Apache Superset with MySQL HeatWave.

I just released a new version of the Terraform modules including some configuration parameters for a future development related to High Availability.

So let’s see the easiest way to deploy Superset on OCI using MySQL HeatWave.

Quick Deployment

The default deployment is the following:

The fastest and easiest way to deploy such architecture is to click on the button below:

When you click on the button, you will reach the following screen if you are …

If like me you are an old experienced MySQL DBA, to analyze your MySQL workload, you certainly have used the slow query log with long_query_time set to 0.

The slow query log is a file that contains all the queries whose execution time is greater than the value of long_query_time. This file can be huge and uses up all available disk space on busy systems.

Constantly writing to that file can also add an overhead to the server.

For those reasons, the slow query log is not available in MySQL Database Service (HeatWave) in OCI.

Plan B ?

As a DBA, what are my options for finding the queries that need to be optimized? As usual, the queries that consume the most time are the ones that need some attention

It can be a very long query or a short query executed too many times.

Currently the MySQL DBAs use …

Apache Airflow is an open-source workflow management platform for data engineering pipelines.

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

I am sharing Terraform modules you can use to deploy in your architecture:

Architectures

With the modules you can deploy architectures like these:

with a single MDS instancewith MDS High Availabilitywith HeatWave Cluster

We will use the exact same modules built into a stack for OCI’s Resource Manager. This will allow us to deploy the architecture just in few clicks.

Deployment

We open in a browser the following GitHub repository: …

Recently I blogged about how to easily deploy a LAMP application to MDS.

Using the Terraform module (OCI Resource Manager’s Stack) you also have the possibility to choose the PHP version to install:

But as you should already know, not all versions support the latest default authentication method in MySQL 8.0: caching_sha2_password [1], [2], [3].

Most of the PHP applications are using mysqli and mysqlnd …
