All systems from application and database have to proceed a regression test or series of QA testing until everything has passed. For large enterprise companies, it’s common practice to always do a regression test on a targeted QA environment or staging environment where the upgrading of the database servers to its major version has first to be applied. While backup provides data to feed in case you need to restore to its primary state if unforeseen problems occur, upgrading to a major release has to be tested first into a development or staging machine. If you are not prepared yet on what type of backup you need, you might have to check the best practices when taking a backup. You can use tools such as mariabackup or mydumper or, if you are a ClusterControl user, then use the Database Backup Management tool. In this case, always provide backup to your data. In case upgrading the system caught up with issues that were left unobserve, then it can bring impact to your business. So in this case, you always have a failback mechanism planned and setup ahead of the upgrade. However, it’s not always that your system has to stay constant, it has to be upgraded to avail security patches, bug fixes, and advance features that are present on the newer version releases. You might hit Google to find the term but basically, it’s always best not to touch normal health especially the normally functioning systems. This simple jargon defines the term we call SNAFU. It’s not always the best method to upgrade your database live in production without doing a test. We’ll take it step-by-step on what are the things you need to consider for upgrading. With all of these changes, it’s best to deliver this blog to provide a guide on how to upgrade MariaDB 10.4 to MariaDB 10.5. If you’re curious about whatever reason they say, please check out MDEV-15058. For example, take note that in MariaDB 10.5, innodb_buffer_pool_instances has already been marked as deprecated while it is set to be removed in version 10.6. MariaDB 10.5 also boasted its improvements with the InnoDB storage engine for its performance and some new variables are also presented but major deprecated variables have been marked deprecated or totally removed. It also features sophisticated handling for privileges extending its granularity which enables a DBA for example to provide limited privileges on a particular database user for tight security of your database. In the release, there has been added support for Amazon S3 or any third-party public or private cloud that supports S3 API. MariaDB 10.5 was released as GA in June 2020.
