As a sidenote Magento 2.3 has indexing issues with 10.3 which can cause crons to run for hours using high resources.This has been nasty. Any server running Magento v2 has been crashing for me. It uses a lot of FTS and FK.
Affects MariaDB 10.1 to 10.3 too.
Yes, you can. I was able to without any issues. My MariaDB was showing non-active and would not activate/run. You may need to restart the server or SQL Server after doing the downgrade. Mine was up and running with no restart but I restarted it anyway as the "Status" of MarianDB was still showing "down". This has not resolved the status shows "down" tho. Even tho it is up and running now and the sites are connecting to the database once again.Can you downgrade if mariadb is already down?
Going a bit off-topic but it looks like the indexing issue is being looked at. Catalog Category Indexing takes very long on MariaDB 10.3 with many products · Issue #25199 · magento/magento2As a sidenote Magento 2.3 has indexing issues with 10.3 which can cause crons to run for hours using high resources.
This, in conjunction with the Magento 2.3 layered navigation bug (when using mysql catalog search) crashes the servers. We migrated Magento back to 10.1 servers to resolve indexing issues and used Elasticsearch to avoid the search bug.
I seem to be unable to downgrade. I get the following output. Any suggestions?
# yum downgrade MariaDB-server MariaDB-common MariaDB-shared MariaDB-client MariaDB-compat MariaDB-devel
