Hi Andrew,
no worries, MySQL 8 will perform fine.
The supported database systems for schedulix are basically
PostgreSQL, MySQL, MariaDB and Ingres.
And as long those products don't abandon the SQL standard, they will work in any version.
This means that there might be a lowest version supported, but so far there's no highest version supported.
schedulix executes a few halfway complex queries at startup. But after that it does only
INSERT ... VALUES ...
UPDATE ...
WHERE primary_key = ...
DELETE ...
WHERE primary_key = ...
Any release of a relational DBMS that drops support for such queries simply won't be used by anyone.
Best regards,
Ronald
