A few weeks ago, we did a Galera Cluster webinar on Managed Galera Clusters on DigitalOcean.

MySQL 8.0 is now over four years old and Oracle released the latest quarterly offering today with MySQL 8.0.30, which comes with lots of bug fixes and some interesting additions.  This is my take on the release notes for those who do not have the time to wade through them, comments in italics are my comments and reflect the views of only me. 

This is an interesting release with a good many bug fixes and I urge those who need fixes to upgrade as soon as they can. For everyone else, the TL;DR is that unless you are on the Oracle Cloud Infrastructure or one of the fixed bugs is causing you problems, then upgrade at your leisure.

Dropping or removing an unused table from a database schema can be challenging. Even after triple checking that all of your apps have migrated away from querying the table, there may still be that one rogue script that accesses it. Running the dreaded DROP TABLE statement can cause a host of unintentional problems if that table is still being used elsewhere. It completely erases the table definition, partitions, and the data in that table. Before you drop a table, you should double (or triple!) check when a table was last queried. When was the table you want to drop last accessed? You can manually check when a table was last accessed, but it's a bit complicated. The following query will show you the last time a table was written to, but not read:SELECT update_time FROM information_schema.tables WHERE table_name='tablename'

To see time last accessed in general, you can use the audit plugin for MySQL Enterprise edition that allows you to see …

Learn about how we’re making it safer to drop tables and easier to detect if they’re still in use.
