As databases grow, DBAs and developers often face a tough choice:
+ Keep historical data in production tables and risk slow queries
+ Archive it and lose fast access

With HeatWave, you don’t have to choose. You can archive old partitions, keep recent data in production, and still run lightning-fast queries across all your data.

Have you already tried to upgrade the MySQL version of your MySQL HeatWave instance in OCI that is deployed with Terraform? When you tried, you realized, I hope you didn’t turn off backups, that the instance is destroyed and recreated new! This is our current MySQL HeatWave DB System deployed using Terrafrom: And this is […]

Efficiently loading CSV data into your MySQL environment is a crucial step for many analytical workloads, especially when dealing with the substantial datasets common in today's data-driven world. Both MySQL Shell's parallel import utility and HeatWave's Auto Parallel Load feature offer robust and effective solutions, each catering to slightly different needs and environments.

MySQL Shell's util.importTable provides a flexible and powerful way to import data from various sources, including local disks and OCI Object Storage, into your standard MySQL tables. It's a developer-friendly tool that offers granular control over the import process.

For those leveraging the analytical power of MySQL HeatWave, the sys.heatwave_load stored procedure, particularly with its Auto Parallel Load capabilities, simplifies the often complex task of getting data into the in-memory columnar store.

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 …

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 …

If you use MySQL Shell for Visual Studio Code, using a bastion host is the easiest method to connect to a MySQL HeatWave DB Instance on OCI.

If you already have a connection setup using a bastion to host, you may experience the same problem as me, MySQL Shell complains about an invalid fingerprint detected:

This error has nothing to do with the fingerprint of your user OCI Key. The problem is related to the key of your bastion host as you can see in the output window:

This happens if you have changed your bastion host for example.

To resolve the problem, remove the current ssh host key for the bastion host stored in your know_hosts:

$ ssh-keygen -R "host.bastion.us-ashburn-1.oci.oraclecloud.com"

Use the name of your bastion host of course.

When done, it’s already fixed, you can connect back to your MySQL HeatWave DB Instance using MySQL Shell …
