database - Modifying MySQL table -
how modify mysql table hundreds of records being inserted every second without having downtime / losing data or errors .
ex: adding new field
thanks
gut feel says should avoid modifying table. alternative add column new table , link original table maintain referential integrity, original table remains untouched.
another, typical approach create new table added column, swap out old table , add data new table. not great solution though.
mysql gurus disagree me.
