Yes this is the keypoint. There is a famous blogpost on how to address this which boils down to acquiring a lock explicitly with a very short timeout, and only after acquiring the lock the alter statement is executed. Do this in a loop and essentially it prevents the disaster, but it might fail the migration if unable to take the lock (just repeat the migration) |
