Amazon Linux 2 has outdated MariaDB

Hi, Amazon does not automatically update MariaDB since the database changes are not backward-compatible with some existing applications. Amazon Linux 2 as of today (July 19 2022) supports up to Maria 10.6 but you would have to manually perform these major version updates.

For further clarification see the resources below:

I understand they can't just automatically upgrade everybody that's on 10.5 to 10.6, but there's no reason they can't add a separate mariadb10.6 repo to amazon-linux-extras like they do for php7.4 and php8.0.

I have switched to using MariaDB's official repo for RHEL 7 and their packages are up to date and work fine of Amazon Linux 2.
