Even though I used a dedicated Kubernetes cluster to host my test database, I had this belief that by not explicitly allocating (or requesting, in Kubernetes vocabulary) CPU resources to my Percona XtraDB Cluster (PXC) pods or yet making just a small request, Kubernetes could be delaying access to the free CPU cycles available on […]

Percona Operator for MySQL, based on Percona XtraDB Cluster (PXC), provides configuration to expose the ProxySQL, HAProxy, and the PXC instances themselves so that you can use Percona Toolkit to connect to MySQL from these endpoints externally. However, you can also create Kubernetes pods to run Percona Toolkit operations there instead if you do not […]

In current times, there is a high degree of focus on ensuring the availability and recovery of your production data. This can be challenging at times when using DBaaS solutions in the public cloud space, for example, when using AWS Aurora. Relying solely on a single cloud provider for database services can pose significant risks. […]

MySQL 9.0.0 has brought the VECTOR datatype to your favorite Open Source Database. There are already some functions available to deal with those vectors: This post will show how to deal with vectors and create our own functions to create operations between vectors. We will use the MLE Component capability to create JavaScript functions. JS […]

MySQL HeatWave 9.0 was released under the banner of artificial intelligence. It includes a VECTOR datatype and can easily process and analyze vast amounts of proprietary unstructured documents in object storage, using HeatWave GenAI and Lakehouse. Oracle Cloud Infrastructure also provides a wonderful GenAI Service, and in this post, we will see how to use […]

In MySQL HeatWave, the Database as a Service (DBaaS) offered by Oracle, Machine Learning is incorporated to provide database administrators (DBAs) and developers with an optimal experience.

Those tools are the Auto ML advisors like the autopilot indexing for example.

MySQL HeatWave is also an invaluable asset for Data Analysts, offering straightforward tools that streamline the process of creating predictive models through data training and scoring.

The Data

The data we are using is the Bank Marketing data related to marketing campaigns over phone calls of a Portuguese banking …

MySQL HeatWave is the MySQL DBaaS provided by Oracle in OCI and some other clouds. Compared to the vanilla MySQL, one of the key features of the service is that it allows you to run analytics queries (aka OLAP) very quickly using the HeatWave cluster. You can also run such queries on files using LakeHouse.

When we talk about analytics, we also think about data visualization solutions. In OCI, you can use Oracle Analytics Cloud.

In this article, we explore the procedure to establish a connection between Oracle Analytics Cloud (OAC) and a MySQL HeatWave DB instance within Oracle Cloud Infrastructure (OCI).

Deploying OAC

We consider that you already have a DB System up and running in OCI. The first step is then to deploy an Analytics …

Now this is far from being any observability manual for your InnoDB Cluster and let alone go into everything MySQL Shell API Admin, or the collectDiagnostics utility. You can also use the default javascript commands that we all know and love via dba.getCluster() and so on, but here’s a different take.

I just want to share something I’ve been playing with to pull out some key info from mycluster. Hope it helps someone else out there.

General setup:

select cluster_id, cluster_name, description, cluster_type, primary_mode, clusterset_id
from mysql_innodb_cluster_metadata.clusters;

Members of our cluster:

select * from …

It’s a common scenario to have a Percona Monitoring and Management (PMM) server running on Kubernetes and also desire to monitor databases that are running outside the Kubernetes cluster. The Ingress NGINX Controller is one of the most popular choices for managing the inbound traffic to K8s. It acts as a reverse proxy and load […]

You may have noticed that MySQL now supports creating functions (and store procedures) in Javascript using GraalVM.

This new functionality is only available in MySQL Enterprise and MySQL HeatWave.

As a developer, you can also get free access to MySQL Enterprise from Oracle Technology Network (OTN): MySQL Enterprise Download.

I also recommend you look at Øystein’s presentation during the Belgian MySQL Days: [1], [2].

Why use a JS function?

As you may know, UUIDs are increasingly popular and their usage in MySQL is limited to the UUID V1.

I already covered this in the blog post titled …
