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.

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.

Schema changes are required to add new features or to fix bugs in an application. However, there is no standard procedure to make the changes in a quick and safe manner. If the changes are not made considering the necessary precautions, you may face unwanted outages on the database that can cause serious problems to your business. In this blog post, I will delve into the most important things to consider while preparing a schema change.

Table size and concurrency

When assessing a schema change, one of the most important things to consider is the table size and concurrency. For small tables, the ALTER operation usually takes a few milliseconds up to a few seconds. Here is where concurrency plays another important role: if the table has periods of low concurrency during the day and the application allows having it locked for a few seconds or minutes, …
