In practice, how often do schema migrations take place though?
- mappu 11y agoLooking over the source history at $DAYJOB, we run a migration containing DDL statements on average every two days. Mostly for adding new features on small(er) metadata tables where the ALTER doesn't hurt - but occasionally on our bigger XX-GB log tables, where it takes all morning.
