MySQL 8.0.29 and Percona XtraBackup Incompatibilities

Feed: Planet MySQL; Author: Marcelo Altmann; Earlier last week, Oracle released their Q2 releases series. Unlike previous releases, backward compatibility has now been broken with previous versions of MySQL. MySQL 8.0.29 extended the support for the online DDL algorithm INSTANT. Prior to 8.0.29 only adding columns to the end of the table was supported. In 8.0.29, this functionality was extended to allow the INSTANT algorithm the ability to add columns in any position of the table as well to drop columns. This new functionality required the redo log version to increase and new redo log types to be added, thus ... Read More

A Quick Peek At MySQL 8.0.29

Feed: Planet MySQL; Author: David Stokes; Oracle released MySQL Server 8.0.29 on April 26th and this is a quick review of the release notes. I have put my own comments in italics. So what is in the ’29 release of MySQL Server? Does it come festooned with new, neat features or is it a big bug-fix bonanza? The TL;DR While this server release has some interesting stuff, there is no compelling feature that will necessitate an immediate upgrade. Read through the release notes to see if anything in there that is a must for you but for most of us, ... Read More
MySQL 8.0.28 Quick Peek

Feed: Planet MySQL; Author: David Stokes; Oracle released MySQL 8.0.28 on January 18th with little fanfare, as part of their four times a year release cycle. So what is included in the new release? Over the past few years, there have been some cool new features included in these ‘dot’ releases that some in the community say would have been better off being labeled as a major release. But what is in .28? Below are the more interesting changes in the database server and the shell, as there was not a whole lot changed in the other products such as ... Read More

Sysbench for arm and MySQL 8.0
Feed: Planet MySQL; Author: Frederic Descamps; For my presentation for the next FOSDEM MySQL Devroom, I needed to create some load. As usual, for this task, what better than sysbench ? The “problem” was that my system was already setup and I used OL7 on the always free Ampere compute instance on OCI. As you may know, this is an ARM architecture (aarch64) and there was not sysbench rpm package available for this OS and architecture. I also wanted to have sysbench compiled and linked with MySQL 8.0 libraries [], []. And this is why I built this package that ... Read More
Online DDL with Group Replication In MySQL 8.0.27
Feed: Planet MySQL; Author: Marco Tusa; Last April 2021 I wrote an article about Online DDL and Group Replication. At that time we were dealing with MySQL 8.0.23 and also opened a bug report which did not have the right answer to the case presented.
Anyhow, in that article I have shown how an online DDL was de facto locking the whole cluster for a very long time even when using the consistency level set to EVENTUAL.
This article is to give justice to the work done by the MySQL/Oracle engineers to correct that annoying inconvenience.
Before going ahead, let ... Read More
