Do you want MySQL with the best possible performance? Then stick to version 5.6, as long as you don't mind it's been EOL for 12 years. 5.7 also has better performance than newer versions, although not as good as 5.6. Some performance regressions are just not being fixed.

^^ Veteran database performance guru, Mark Callaghan, former tech lead for MySQL at Facebook and Google, is now an independent consultant who blogs about database benchmarking.

(For my own account as a MariaDB fanboy I must add that another option could be migrating to MariaDB which is a plug-in replacement for MySQL 5.6, as MariaDB has done a better job at avoiding and fixing performance regressions.)

Got a bit panic-scared by my website's database going down this morning, with #VirtualMin not clearly telling me that it was due to MariaDB having crashed due to an out-of-memory problem, so I filed this little UX issue: github.com/virtualmin/virtualm

…and then filed this somewhat more important issue about needing an integrated way to detect and repair crashed #MariaDB / #MySQL tables: github.com/virtualmin/virtualm

Running Virtualmin version 7.30.8 (from your Debian 12 repositories) on my personal server, this morning when my website indicated a database problem and I went into VirtualMin to see what was goin...

@MartinEscardo This is true. I'm suggesting that this is not just a computer engineering thing. I'm saying that at base, nature itself is non-binary, and we are non-binary, and we abstract things we don't understand into black and white distinctions to make them easier to understand. It's fast and efficient to ignore certain problems. There are still problems with binary logic.

Did you know that SQL is one of the few computer languages to use 3-valued logic? Databases are highly exposed to the problems of inconsistent or missing information. But we can use binary logic to simulate 3-valued logic (MySQL uses the paraconsistent logic LP by Graham Priest, but you can use that to create a fully relevant implication as in RM3, it's just a longer expression)

Well it look a better part of the day and a number of trial and error (as the documentation is a bit outdated in some cases), but I got there in the end!

This was a test instance migration, and it works!

Officially now on Postgres 17.5.

Time to document it all and get some sleep as I will have to redo all this again.
