Find the official MySQL container image in the Oracle Container Registry

If you are deploying MySQL on containers, one of the first tasks is to find the right image.

There’s a certain amount of confusion, especially when we’re trying to help someone who’s having problems with their deployment.

For example, when people say I’m using the official docker image… what does that really mean?

Docker Hub, provides their official image (https://hub.docker.com/_/mysql), but this is not the official MySQL image that we, the MySQL Team at Oracle, support.

Before the mess with Docker Hub ([1], [2], [3]), the real official images for MySQL …

By integrating MySQL database migrations into your testing process, you can not only ensure your testing database is up to date with the most recent changes, but you can also test that the migrations themselves are performing as expected. In this post we will walk you though how to incorporate migrations with Knex and run those migrations on your test database being run in Testcontainers.

We now added a new automated capability (AutoLoad) to MySQL Autopilot – Auto Load & Auto Unload which continuously monitors workload run in MySQL and use machine learning model to predict the queries that can offload to HeatWave for query acceleration. Based on the list of queries, the new AutoLoad dynamically loads or unloads tables to HeatWave cluster.

We are excited to introduce the JSON support in HeatWave which offers significant performance improvement with no change in applications, or no indexes needed for accelerating JSON processing. This provides significant enhancement for applications that heavily rely on JSON data structures, as query execution times are now drastically reduced, improving overall application performance.

As a MySQL database administrator, you’re likely familiar with the SHOW REPLICA STATUS command. It is an important command for monitoring the replication status on your MySQL replicas. However, its output can be overwhelming for beginners, especially regarding the binary log coordinates. I have seen confusion amongst new DBAs on which binary log file and position represent what in the replication.

In this guide, we’ll simplify the SHOW REPLICA STATUS output, focusing on the critical binary log coordinates essential for troubleshooting and managing replication.

The key binlog coordinates

Before we delve into the output, let’s understand the key binlog coordinates we’ll be working with:

• Master_Log_File: This is the name of the primary binary log file that the I/O thread is currently reading from.
• Read_Master_Log_Pos: It represents the …

To mark the 3rd day of Oracle CloudWorld 2023, Oracle announced significant enhancements to MySQL HeatWave. Hear what leading Industry Analysts have to say about the latest Vector store and generative AI innovations.

If you’re a DBA, one of your “easiest” tasks is to stop/start MySQL during a maintenance window, but even that could lead to unwanted scenarios if you modify some dynamic parameters at some point in your instance.

Here’s a brief story of how this could happen, to make it clearer:

You’re a DBA managing a few MySQL servers. The application using one of them starts having issues on a Friday night, right before it’s time to leave; after a quick check, you notice the app is requesting more connections, and the hotfix is to up max connections; you change them dynamically, the fire is off, and so are you. Let your future self worry about finding the root cause and fixing it properly the following Monday.

But life happens; Monday is here with new challenges, and you already forgot about the connections issue… A few months later, a restart for MySQL is required, and surprise, surprise, right after …

MySQL HeatWave announced new and enhanced capabilities during Oracle CloudWorld 2023, including support for vector store, generative AI, new in-database machine learning features, MySQL Autopilot enhancements, new HeatWave Lakehouse capabilities, support for JavaScript, acceleration of JSON queries, and support for new analytic operators. This blog provides a technical deep dive into these enhancements.

In the world of data backup and security, physical backups play an extremely important role. Physical backup methods are faster than logical because they involve only file copying without conversion. This type of backup is suitable for large, important databases that need to be recovered quickly when problems occur.

Physical backups are the backups that consist of raw copies of the directories and files that store database contents. In addition to databases, the backup can include any related files, such as log or configuration files. Now, since backup speed and compactness are important for busy, important databases, Percona’s open source physical backup solution – Percona XtraBackup (PXB), takes into account all these aspects and benefits MySQL world with its exceptional capabilities!
