They don't change the on-disk structure all the time though...
- jeltz 4mo agoMostly because MySQL development is slower.
- evanelias 4mo agoEven when MySQL development velocity was more rapid, they maintained binary table format compatibility across major version upgrades the vast majority of the time. Literally the only exception I can think of, which necessitated a table rebuild, was the fractional timestamp storage change when going from MySQL 5.5 (2010) to 5.6 (2013).
