Well, I currently use version 10.1 of MariaDB on my server with cPanel. I thought about upgrading to version 10.2 to see if I get a little performance.
However, the following warning is displayed for me:
MariaDB enables "strict mode" by default as of version 10.2. Strict mode controls how MariaDB and MySQL handle invalid or missing values in data-change statements such as INSERT or UPDATE. Applications not built with strict mode enabled may cause undesired behavior; please Verify applications using MariaDB are compatible before upgrading. More information about strict mode is available here.
What problems can I have with my system if I upgrade? Should I change something in system programming to be compatible with this strict mode ? Which, by the way, I do not even know what it is.
The system is all done in PHP, and uses connection to mysqli.
