For a long time, I’ve been thinking about the possibility of importing a single file with multiple connections. Why? Simply because we have scenarios where we end up importing a big file with a single loader thread. Well, I have good news: since the release of 0.16.3-1, we are able to do it. There are […]

As you can read in my previous post related to MySQL 9 and authentication, the old mysql_native_password plugin has been removed. In that post, I showed an example using PHP 7.2, the default version in OL8. If you are using PHP and you want to use MySQL 9, you must be using a more recent […]

With the latest MySQL Innovation Release, we decided that it was time to remove the remaining weak authentication plugin: mysql_native_password. We previously deprecated it and made it not default loaded in MySQL 8.4 LTS and, now, in 9.0 it’s gone! Reasons Oracle places significant attention on the security of all its products, and MySQL is […]

On July 1st, 3 new releases of MySQL came out. Indeed, we released the next 8.0 (8.0.38), the first update of the 8.4 LTS (8.4.1), and the very first 9.0 as Innovation Release. We now support 3 versions of the most popular Open Source database.

With these releases, we also want to thank all the great contributors who send patches to MySQL.

For some time now, all the contributors have also been highlighted in the Release Notes, but we never thank enough, so let’s take back the good habits of listing them in a dedicated blog post.

Some contributions were merged into multiple versions. Let’s have a look at all these contributions:

MySQL 9.0 was released on July 1, 2024. This is an ‘Innovation’ release, which means it provides access to the latest features and improvements in MySQL technologies. Innovation releases are the opposite of the Long Term Support (LTS) releases, where stability is the top priority, and only needed security and other fixes are available. This […]

When running tests, it is sometimes useful to slow down IOs to clearly show the impact of reading from the disk.  Modern laptops and servers usually have fast local SSDs, and most cloud vendors provide, in addition to fast local disks, relatively fast network block devices (EBS for AWS and Persistent Disk for GCP).  Even when using magnetic network block devices, IOs are not guaranteed

Some of our Percona Support customers report performance degradation after a major MySQL upgrade, and there can be many different reasons for this. These days, the most common major upgrade is from MySQL 5.7 (which recently reached EOL) to 8.0, and I am going to emphasize one important case that affects many database instances. Range […]

Is your MySQL database running at its best? While MySQL is known for its reliability and ease of use, ensuring top-notch performance is crucial. One way to do that is through performance monitoring, an essential practice for identifying bottlenecks, maintaining optimal speed, and guaranteeing a seamless user experience. Effective monitoring not only helps in detecting […]

Replication has been the core functionality, allowing high availability in MySQL for decades already. However, you may still encounter replication errors that keep you awake at night. One of the most common and challenging to deal with starts with: “Got fatal error 1236 from source when reading data from binary log“. This blog post is […]
